=== Why 15h? ===
Released between 2011 and 2014, AMD's [[fam15h]] (and its approximately-contemporaneous relatives, [[fam10h]], [[fam14h]] and [[fam16h]]) are the final high-performance x86_64 microprocessors lacking most of the limitations newer x86 platforms are encumbered by. In many cases, fam15h hardware can provide a performant, full-featured system, using entirely free and open source software. It enforces no firmware signing (allowing things such as [[coreboot]]), can be booted entirely with free firmware (including memory initialization), and it requires no privileged management coprocessor (such as the Platform Security Processor or Management Engine, found on newer AMD and Intel platforms respectively). Where a [[Board Management Controller]] is present, it can usually reliably disabled, or better yet, flashed with [[OpenBMC]]. On fam10h, even microcode is unencrypted and unsigned, and can be modified by the user.

Beyond their currently-unparalleled degree of firmware freedom for a modern x86_64 platform, AMD hardware of this era (in particular, 6200 and 6300-series [[Opteron]] platforms) remains a powerful and cost-effective option for many systems, especially under parallel workloads. Despite this, the comparative popularity of competing Intel processors during this era has limited the familiarity and uptake of these pre-Zen AMD platforms among many enthusiasts.

If you are looking for an x86_64 platform under your complete control, this website serves to demystify fam15h and its relatives, so that these systems can remain in operation well into the future.

=== What hardware was that again? ===
Robust support for coreboot on select fam15h motherboards has been developed and thoroughly tested at 15h.org. The current, production ready motherboards are [[KGPE-D16]], [[KCMA-D8]], [[H8QG6]], [[H8SGL]], and [[H8SCM]]. A handful of other fam15h motherboards have [[Motherboards|preliminary support]]. For these motherboards, the [[Bulldozer]] and [[Piledriver]] microarchitectures are supported by [[coreboot-15h]].

Build Guide

Dodoid: recommend RDIMM

[[File:Komos_sabertooth.png|thumb|[[Komos]] - a build using the [[AM3+]] [[Sabertooth 990FX R2.0]]]]
Since you're reading the 15h.org build guide, we'll assume you're interested in building a fully-FOSS-firmware-compatible AMD system to run [[coreboot-15h]]. This guide assumes you're looking to build a new desktop, server, or workstation system from separately-purchased components.

If you are ''not'' building from separate components (such as for the various prebuilt [[Supermicro]] servers which included compatible motherboards), head over to the [[Motherboards]] page and look for your board's model. For laptops, see the [[Laptops]] page.

== Choosing a Platform ==
coreboot-15h is available for many motherboards, across several different AMD sockets - which one you should choose depends on

[[#Building with AM3+|Choose AM3+]] if you are looking for higher single-thread performance in a desktop or gaming system with up to 8 cores and 64GB of memory. Desktop users will generally find high-clocking AM3+ systems "feel" faster than lower-clocking server platforms, and they are likely to perform better in gaming and web browsing.

[[#Building with G34|Choose G34]] if you are building a server or workstation system requiring higher multicore performance (at the cost of lower single-thread performance). Most G34 motherboards are dual-socket (up to 32 cores, 512GB RAM), but boards with 1 (up to 16 cores, 256 GB RAM) and 4 (up to 64 cores, 1TB RAM) sockets are also available.

[[#Building with C32|Choose C32]] for a middle-ground between these - 1 or 2 sockets, up to 16 cores, clockspeeds in between AM3+ and G34, and up to 512GB of RAM.

All of these platforms support ECC memory, and are based on [[Orochi]] - AMD's high-power, high-performance platform for [[Family 15h]] systems. If you're looking to build a lower-power quad-core system (such as for an efficient router or media player machine), you may be interested in a [[Trinity|Trinity/Richland]] or [[Kabini]] APU instead. For these, choose an [[FM2]] board for midrange desktop systems, or [[AM1]] for low-power systems with lightweight applications.

== Building with AM3+ ==
coreboot-15h supports [[Socket AM3+]] on the ASUS [[Sabertooth 990FX R2.0]] and [[Crosshair V Formula-Z]]. The fastest AM3+ is the 8-core FX-9590. This platform uses DDR3 UDIMM (ordinary desktop RAM) in the usual dual-channel, 2-DIMM-per-channel configuration, and also optionally supports (UDIMM) ECC memory - DIMMs up to 16GB each are supported, for up to 64GB total.

As a consumer gaming platform, CPU coolers for AM3+ are common and still widely-available.

Unlike modern desktop CPUs (and other CPUs of its time), AM3+ is PGA socket, with pins on the CPU and holes in the socket. Be careful to avoid bending pins on the CPU during installation and removal. The socket on the motherboard is typically harder to damage.

== Building with G34 ==
[[File:Qubesotron_2026.jpeg|thumb|[[Qubesotron]] - a build using the [[G34]] [[KGPE-D16]]]]

[[Socket G34]], usually on the [[ASUS KGPE-D16]], is probably the most popular and best-known platform for FOSS firmware on AMD systems. G34 motherboards were made with 1, 2, and 4 sockets, and coreboot-15h supports boards covering all of these configurations. The fastest G34 CPU is the 16-core Opteron 6386 SE, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 4 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. RDIMMs up to 32GB, or LRDIMMs up to 64GB each, are both supported. Despite this, two 32GB RDIMMs can be used per channel, versus only one 64GB LRDIMM - this means that the memory limit is 256 GB per socket, whether you use RDIMM or LRDIMM memory. RDIMM is generally the fastest, least-expensive and most-compatible option.

Good G34 CPU coolers can be difficult to find - many G34 servers used passive CPU coolers reliant on specific fan and baffle arrangements, which are not easily adapted for standard PC cases in custom-built systems. A list of relevant CPU coolers is available on the [[Coolers]] page - the rare Noctua G34 coolers are well-regarded and highly-prized, while Dynatron active server coolers are sometimes still available used. Depending on what you can find, it may be easier to [[Cooler_Adapter|adapt a modern CPU cooler to fit]] instead.

G34 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a G34 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== Building with C32 ==
[[Socket C32]] motherboards covering both 1 and 2 socket configurations are supported. The fastest C32 CPU is the 8-core Opteron 4386, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 2 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. Unlike with G34, C32 CPUs support 64GB LRDIMMs in ''all'' slots - this means that, despite having half as many slots, C32 motherboards surprisingly support the same 256 GB per socket as G34, albeit with fewer channels.

C32 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a C32 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== PCI Express Devices ==
[[File:PM1725a.jpg|thumb|A Samsung PM1725a HHHL SSD - note the PCIe x8 card edge]]

The [[Family 15h]] and [[Family 16h]] platforms supported by coreboot-15h support up to PCI Express 2.0 ("Gen2") - a single Gen2 x16 slot delivers 8 GB/s of bandwidth. Compared to newer platforms, this can be a notable limitation for bandwidth-intensive devices such as GPUs or NVMe storage. For this reason, it's a good idea to select PCIe devices with more lanes whenever possible.

This table shows the throughput of all PCIe lane widths, from Gen1 through Gen5. The advantages of additional PCIe lanes on a Gen2 chipset should be clear - a Gen2 x16 link provides comparable bandwidth to a Gen3 x8, or a Gen4 x4.

=== GPUs ===
Most high-end PCIe GPUs (old and new) support using all 16 lanes, but certain newer midrange cards are x8 or x4.

=== NVMe SSDs ===
[[File:M.2 Adapter.webp|thumb|A common generic M.2 adapter card kit. The bottom slot is for PCIe M.2 drives, the top slot (and cable) are for SATA M.2 drives.]]

Few motherboards supported by coreboot-15h have built-in M.2 slots. However, a PCIe M.2 SSD can be used in a PCIe slot using a common NVMe-to-x4 adapter card (many also allow an additional M.2 SATA SSD to be connected to a SATA port). A Gen2 x4 slot provides 2 GB/s of PCIe bandwidth - if your SSD's sequential read and write speeds are below 2000 MB/s, PCIe 2.0 will not bottleneck it. However, many NVMe SSDs are capable of more.

Higher NVMe bandwidth on these platforms requires an SSD with more than 4 PCIe lanes - since the M.2 connector is only x4, this means using an AIC (Add-In Card)-format SSD, which installs directly in a PCIe slot. The following AIC SSDs are known to be capable of more than 2000 MB/s sequential throughput over at least 8 PCIe lanes:

Most G34 motherboards are dual-socket (up to 32 cores, 512GB RAM), but boards with 1 (up to 16 cores, 256 GB RAM) and 4 (up to 64 cores, 1TB RAM) sockets are also available.

[[#Building with C32|Choose C32]] for a middle-ground between these - 1 or 2 sockets, up to 16 cores, clockspeeds in between AM3+ and G34, and up to 512GB of RAM.

All of these platforms support ECC memory, and are based on [[Orochi]] - AMD's high-power, high-performance platform for [[Family 15h]] systems. If you're looking to build a lower-power quad-core system (such as for an efficient router or media player machine), you may be interested in a [[Trinity|Trinity/Richland]] or [[Kabini]] APU instead. For these, choose an [[FM2]] board for midrange desktop systems, or [[AM1]] for low-power systems with lightweight applications.

== Building with AM3+ ==
coreboot-15h supports [[Socket AM3+]] on the ASUS [[Sabertooth 990FX R2.0]] and [[Crosshair V Formula-Z]]. The fastest AM3+ is the 8-core FX-9590. This platform uses DDR3 UDIMM (ordinary desktop RAM) in the usual dual-channel, 2-DIMM-per-channel configuration, and also optionally supports (UDIMM) ECC memory - DIMMs up to 16GB each are supported, for up to 64GB total.

As a consumer gaming platform, CPU coolers for AM3+ are common and still widely-available.

Unlike modern desktop CPUs (and other CPUs of its time), AM3+ is PGA socket, with pins on the CPU and holes in the socket. Be careful to avoid bending pins on the CPU during installation and removal. The socket on the motherboard is typically harder to damage.

== Building with G34 ==
[[File:Qubesotron_2026.jpeg|thumb|[[Qubesotron]] - a build using the [[G34]] [[KGPE-D16]]]]

[[Socket G34]], usually on the [[ASUS KGPE-D16]], is probably the most popular and best-known platform for FOSS firmware on AMD systems. G34 motherboards were made with 1, 2, and 4 sockets, and coreboot-15h supports boards covering all of these configurations. The fastest G34 CPU is the 16-core Opteron 6386 SE, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 4 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. RDIMMs up to 32GB, or LRDIMMs up to 64GB each, are both supported. Despite this, two 32GB RDIMMs can be used per channel, versus only one 64GB LRDIMM - this means that the memory limit is 256 GB per socket, whether you use RDIMM or LRDIMM memory.

Good G34 CPU coolers can be difficult to find - many G34 servers used passive CPU coolers reliant on specific fan and baffle arrangements, which are not easily adapted for standard PC cases in custom-built systems. A list of relevant CPU coolers is available on the [[Coolers]] page - the rare Noctua G34 coolers are well-regarded and highly-prized, while Dynatron active server coolers are sometimes still available used. Depending on what you can find, it may be easier to [[Cooler_Adapter|adapt a modern CPU cooler to fit]] instead.

G34 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a G34 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== Building with C32 ==
[[Socket C32]] motherboards covering both 1 and 2 socket configurations are supported. The fastest C32 CPU is the 8-core Opteron 4386, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 2 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. Unlike with G34, C32 CPUs support 64GB LRDIMMs in ''all'' slots - this means that, despite having half as many slots, C32 motherboards surprisingly support the same 256 GB per socket as G34, albeit with fewer channels.

C32 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a C32 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== PCI Express Devices ==
[[File:PM1725a.jpg|thumb|A Samsung PM1725a HHHL SSD - note the PCIe x8 card edge]]

The [[Family 15h]] and [[Family 16h]] CPUs supported by coreboot-15h support up to PCI Express 2.0 ("Gen2") - a single Gen2 x16 slot delivers 8 GB/s of bandwidth. Compared to newer platforms, this can be a notable limitation for bandwidth-intensive devices such as GPUs or NVMe storage. For this reason, it's a good idea to select PCIe devices with more lanes whenever possible.

This table shows the throughput of all PCIe lane widths, from Gen1 through Gen5. The advantages of additional PCIe lanes on a Gen2 chipset should be clear - a Gen2 x16 link provides comparable bandwidth to a Gen3 x8, or a Gen4 x4.

=== GPUs ===
Most high-end PCIe GPUs (old and new) support using all 16 lanes, but certain newer midrange cards are x8 or x4.

=== NVMe SSDs ===
[[File:M.2 Adapter.webp|thumb|A common generic M.2 adapter card kit. The bottom slot is for PCIe M.2 drives, the top slot (and cable) are for SATA M.2 drives.]]

Few motherboards supported by coreboot-15h have built-in M.2 slots. However, a PCIe M.2 SSD can be used in a PCIe slot using a common NVMe-to-x4 adapter card (many also allow an additional M.2 SATA SSD to be connected to a SATA port). A Gen2 x4 slot provides 2 GB/s of PCIe bandwidth - if your SSD's sequential read and write speeds are below 2000 MB/s, PCIe 2.0 will not bottleneck it. However, many NVMe SSDs are capable of more.

Higher NVMe bandwidth on these platforms requires an SSD with more than 4 PCIe lanes - since the M.2 connector is only x4, this means using an AIC (Add-In Card)-format SSD, which installs directly in a PCIe slot. The following AIC SSDs are known to be capable of more than 2000 MB/s sequential throughput over at least 8 PCIe lanes:

Since you're reading the 15h.org build guide, we'll assume you're interested in building a fully-FOSS-firmware-compatible AMD system to run [[coreboot-15h]]. This guide assumes you're looking to build a new desktop, server, or workstation system from separately-purchased components.

If you are ''not'' building from separate components (such as for the various prebuilt [[Supermicro]] servers which included compatible motherboards), head over to the [[Motherboards]] page and look for your board's model. For laptops, see the [[Laptops]] page.

== Choosing a Platform ==
coreboot-15h is available for many motherboards, across several different AMD sockets - which one you should choose depends on

[[#Building with AM3+|Choose AM3+]] if you are looking for higher single-thread performance in a desktop or gaming system with up to 8 cores and 64GB of memory. Desktop users will generally find high-clocking AM3+ systems "feel" faster than lower-clocking server platforms, and they are likely to perform better in gaming and web browsing.

[[#Building with G34|Choose G34]] if you are building a server or workstation system requiring higher multicore performance (at the cost of lower single-thread performance). Most G34 motherboards are dual-socket (up to 32 cores, 512GB RAM), but boards with 1 (up to 16 cores, 256 GB RAM) and 4 (up to 64 cores, 1TB RAM) sockets are also available.

[[#Building with C32|Choose C32]] for a middle-ground between these - 1 or 2 sockets, up to 16 cores, clockspeeds in between AM3+ and G34, and up to 512GB of RAM.

All of these platforms support ECC memory, and are based on [[Orochi]] - AMD's high-power, high-performance platform for [[Family 15h]] systems. If you're looking to build a lower-power quad-core system (such as for an efficient router or media player machine), you may be interested in a [[Trinity|Trinity/Richland]] or [[Kabini]] APU instead. For these, choose an [[FM2]] board for midrange desktop systems, or [[AM1]] for low-power systems with lightweight applications.

== Building with AM3+ ==
coreboot-15h supports [[Socket AM3+]] on the ASUS [[Sabertooth 990FX R2.0]] and [[Crosshair V Formula-Z]]. The fastest AM3+ is the 8-core FX-9590. This platform uses DDR3 UDIMM (ordinary desktop RAM) in the usual dual-channel, 2-DIMM-per-channel configuration, and also optionally supports (UDIMM) ECC memory - DIMMs up to 16GB each are supported, for up to 64GB total.

As a consumer gaming platform, CPU coolers for AM3+ are common and still widely-available.

Unlike modern desktop CPUs (and other CPUs of its time), AM3+ is PGA socket, with pins on the CPU and holes in the socket. Be careful to avoid bending pins on the CPU during installation and removal. The socket on the motherboard is typically harder to damage.

== Building with G34 ==
[[Socket G34]], usually on the [[ASUS KGPE-D16]], is probably the most popular and best-known platform for FOSS firmware on AMD systems. G34 motherboards were made with 1, 2, and 4 sockets, and coreboot-15h supports boards covering all of these configurations. The fastest G34 CPU is the 16-core Opteron 6386 SE, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 4 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. RDIMMs up to 32GB, or LRDIMMs up to 64GB each, are both supported. Despite this, two 32GB RDIMMs can be used per channel, versus only one 64GB LRDIMM - this means that the memory limit is 256 GB per socket, whether you use RDIMM or LRDIMM memory.

Good G34 CPU coolers can be difficult to find - many G34 servers used passive CPU coolers reliant on specific fan and baffle arrangements, which are not easily adapted for standard PC cases in custom-built systems. A list of relevant CPU coolers is available on the [[Coolers]] page - the rare Noctua G34 coolers are well-regarded and highly-prized, while Dynatron active server coolers are sometimes still available used. Depending on what you can find, it may be easier to [[Cooler_Adapter|adapt a modern CPU cooler to fit]] instead.

G34 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a G34 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== Building with C32 ==
[[Socket C32]] motherboards covering both 1 and 2 socket configurations are supported. The fastest C32 CPU is the 8-core Opteron 4386, and UDIMM, RDIMM, and LRDIMM memory are all supported. Each CPU supports 2 memory channels, and all coreboot-15h-supported boards are 2-DIMM-per-channel. Unlike with G34, C32 CPUs support 64GB LRDIMMs in ''all'' slots - this means that, despite having half as many slots, C32 motherboards surprisingly support the same 256 GB per socket as G34, albeit with fewer channels.

C32 CPUs use LGA sockets, like Intel or newer AMD CPUs. This generally makes the CPU less fragile, but the socket on the motherboard more so. As with modern PC hardware, if you purchase a C32 motherboard without CPUs installed, inspect its sockets closely for bent, damaged, or dirty pins.

== PCI Express Devices ==
The [[Family 15h]] and [[Family 16h]] CPUs supported by coreboot-15h support up to PCI Express 2.0 ("Gen2"). A single Gen2x16 slot delivers Compared to newer platforms, this can be a notable limitation for bandwidth-intensive devices such as GPUs or NVMe storage. For this reason, it's a good idea to select PCIe devices with more lanes where possible. Most high-end PCIe GPUs (old and new) support using all 16 lanes, but certain newer midrange cards are x8 or x4.

'''Family 16h''' (also known as '''fam16h''', or ambiguously as '''fam16''') is a [[CPU Families Overview|family of AMD microprocessors]] corresponding to the [[Jaguar]] and [[Puma]] microarchitectures. All Family 16h processors were APUs, combining a CPU and a "fast-by-integrated-standards" GPU on a single die. Outside the PC hardware space, it is notable for use in the Xbox One and PlayStation 4 families of eighth-generation game consoles.

"16h" (16-hexadecimal) is most correctly pronounced as "one-sixteen six", but most people say "sixteen‑aitch".

Like other AMD family names, 16h ("16 hexadecimal") is a mostly-arbitrary, somewhat-sequential (new processor families receive unused higher family numbers) number, returned by the x86 <code>CPUID</code> instruction as a "Family number", and commonly written in hexadecimal. 16 in hexadecimal corresponds to the number 22 in decimal, meaning that while "Family 22" would also be a valid, if confusing, name for these CPUs, "Family 16" could also refer to [[Family 10h]].

'''Family 15h''' (also known as '''fam15h''', or ambiguously as '''fam15''') is a [[CPU Families Overview|family of AMD microprocessors]] corresponding to the [[Bulldozer]], [[Piledriver]], [[Steamroller]], and [[Excavator]] microarchitectures.

== Notes and Status ==

* All x86 CPUs include proprietary microcode, in ROM on the CPU itself. Later vendor-provided patches, which update part of this microcode, can be loaded at runtime - these patches are proprietary blobs.
* All fam15h CPUs are vulnerable to speculative execution exploits if a microcode patch is not loaded.
* Apart from the above, Bulldozer CPUs are generally stable without microcode updates.
* A microcode update is strongly recommended for Piledriver CPUs because of known virtualization-related bugs in their ROM microcode.
* Trinity APUs and Richland APUs additionally require the SMU firmware blob to run. The SMU (System Management Unit) is the microcontroller inside AMD SoCs/APUs that handles low-level platform management: power, clocks, voltage, thermal control, power states, power-gating, and related sensors/interrupts. The firmware for this microcontroller is a blob, [https://git.15h.org/mrothfuss/coreboot-15h/src/branch/4.11_branch/src/vendorcode/amd/agesa/f15tn/Proc/GNB/Modules/GnbInitTN/GnbSmuFirmwareTN.h included as a large array] in f15tn AGESA. Orochi fam15h platforms (non-APU CPUs with separate northbridges and southbridges) do not require this blob.

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.

Considerations for licensors: Our public licenses are
intended for use by those authorized to give the public
permission to use material in ways otherwise restricted by
copyright and certain other rights. Our licenses are
irrevocable. Licensors should read and understand the terms
and conditions of the license they choose before applying it.
Licensors should also secure all rights necessary before
applying our licenses so that the public can reuse the
material as expected. Licensors should clearly mark any
material not subject to the license. This includes other CC-
licensed material, or material used under an exception or
limitation to copyright. More considerations for licensors:
wiki.creativecommons.org/Considerations_for_licensors

Considerations for the public: By using one of our public
licenses, a licensor grants the public permission to use the
licensed material under specified terms and conditions. If
the licensor's permission is not necessary for any reason--for
example, because of any applicable exception or limitation to
copyright--then that use is not regulated by the license. Our
licenses grant only permissions under copyright and certain
other rights that a licensor has authority to grant. Use of
the licensed material may still be restricted for other
reasons, including because others have copyright or other
rights in the material. A licensor may make special requests,
such as asking that all changes be marked or described.
Although not required by our licenses, you are encouraged to
respect those requests where reasonable. More considerations

Creative Commons Attribution-ShareAlike 4.0 International Public
License

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-ShareAlike 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your
acceptance of these terms and conditions, and the Licensor grants You
such rights in consideration of benefits the Licensor receives from
making the Licensed Material available under these terms and
conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar
Rights that is derived from or based upon the Licensed Material
and in which the Licensed Material is translated, altered,
arranged, transformed, or otherwise modified in a manner requiring
permission under the Copyright and Similar Rights held by the
Licensor. For purposes of this Public License, where the Licensed
Material is a musical work, performance, or sound recording,
Adapted Material is always produced where the Licensed Material is
synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright
and Similar Rights in Your contributions to Adapted Material in
accordance with the terms and conditions of this Public License.

c. BY-SA Compatible License means a license listed at
creativecommons.org/compatiblelicenses, approved by Creative
Commons as essentially the equivalent of this Public License.

d. Copyright and Similar Rights means copyright and/or similar rights
closely related to copyright including, without limitation,
performance, broadcast, sound recording, and Sui Generis Database
Rights, without regard to how the rights are labeled or
categorized. For purposes of this Public License, the rights
specified in Section 2(b)(1)-(2) are not Copyright and Similar
Rights.

e. Effective Technological Measures means those measures that, in the
absence of proper authority, may not be circumvented under laws
fulfilling obligations under Article 11 of the WIPO Copyright
Treaty adopted on December 20, 1996, and/or similar international
agreements.

f. Exceptions and Limitations means fair use, fair dealing, and/or
any other exception or limitation to Copyright and Similar Rights
that applies to Your use of the Licensed Material.

g. License Elements means the license attributes listed in the name
of a Creative Commons Public License. The License Elements of this
Public License are Attribution and ShareAlike.

h. Licensed Material means the artistic or literary work, database,
or other material to which the Licensor applied this Public
License.

i. Licensed Rights means the rights granted to You subject to the
terms and conditions of this Public License, which are limited to
all Copyright and Similar Rights that apply to Your use of the
Licensed Material and that the Licensor has authority to license.

j. Licensor means the individual(s) or entity(ies) granting rights
under this Public License.

k. Share means to provide material to the public by any means or
process that requires permission under the Licensed Rights, such
as reproduction, public display, public performance, distribution,
dissemination, communication, or importation, and to make material
available to the public including in ways that members of the
public may access the material from a place and at a time
individually chosen by them.

l. Sui Generis Database Rights means rights other than copyright
resulting from Directive 96/9/EC of the European Parliament and of
the Council of 11 March 1996 on the legal protection of databases,
as amended and/or succeeded, as well as other essentially
equivalent rights anywhere in the world.

m. You means the individual or entity exercising the Licensed Rights
under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License,
the Licensor hereby grants You a worldwide, royalty-free,
non-sublicensable, non-exclusive, irrevocable license to
exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or
in part; and

b. produce, reproduce, and Share Adapted Material.

2. Exceptions and Limitations. For the avoidance of doubt, where
Exceptions and Limitations apply to Your use, this Public
License does not apply, and You do not need to comply with
its terms and conditions.

3. Term. The term of this Public License is specified in Section
6(a).

4. Media and formats; technical modifications allowed. The
Licensor authorizes You to exercise the Licensed Rights in
all media and formats whether now known or hereafter created,
and to make technical modifications necessary to do so. The
Licensor waives and/or agrees not to assert any right or
authority to forbid You from making technical modifications
necessary to exercise the Licensed Rights, including
technical modifications necessary to circumvent Effective
Technological Measures. For purposes of this Public License,
simply making modifications authorized by this Section 2(a)
(4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every
recipient of the Licensed Material automatically
receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this
Public License.

b. Additional offer from the Licensor -- Adapted Material.
Every recipient of Adapted Material from You
automatically receives an offer from the Licensor to
exercise the Licensed Rights in the Adapted Material
under the conditions of the Adapter's License You apply.

c. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.

6. No endorsement. Nothing in this Public License constitutes or
may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,
the Licensor or others designated to receive attribution as
provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not
licensed under this Public License, nor are publicity,
privacy, and/or other similar personality rights; however, to
the extent possible, the Licensor waives and/or agrees not to
assert any such rights held by the Licensor to the limited
extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this
Public License.

3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified
form), You must:

a. retain the following if it is supplied by the Licensor
with the Licensed Material:

i. identification of the creator(s) of the Licensed
Material and any others designated to receive
attribution, in any reasonable manner requested by
the Licensor (including by pseudonym if
designated);

ii. a copyright notice;

iii. a notice that refers to this Public License;

iv. a notice that refers to the disclaimer of
warranties;

v. a URI or hyperlink to the Licensed Material to the
extent reasonably practicable;

b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and

c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.

2. You may satisfy the conditions in Section 3(a)(1) in any
reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.

3. If requested by the Licensor, You must remove any of the
information required by Section 3(a)(1)(A) to the extent
reasonably practicable.

b. ShareAlike.

In addition to the conditions in Section 3(a), if You Share
Adapted Material You produce, the following conditions also apply.

1. The Adapter's License You apply must be a Creative Commons
license with the same License Elements, this version or
later, or a BY-SA Compatible License.

2. You must include the text of, or the URI or hyperlink to, the
Adapter's License You apply. You may satisfy this condition
in any reasonable manner based on the medium, means, and
context in which You Share Adapted Material.

3. You may not offer or impose any additional or different terms
or conditions on, or apply any Effective Technological
Measures to, Adapted Material that restrict exercise of the
rights granted under the Adapter's License You apply.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database;

b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material,
including for purposes of Section 3(b); and

c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.

b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different
terms or conditions communicated by You unless expressly agreed.

b. Any arrangements, understandings, or agreements regarding the
Licensed Material not stated herein are separate from and
independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

a. For the avoidance of doubt, this Public License does not, and
shall not be interpreted to, reduce, limit, restrict, or impose
conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.

c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the
Licensor.

d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.

The ASUS Sabertooth 990FX R2.0 motherboard well supported by [[coreboot-15h]].

== Open Source Firmware ==
Open source firmware for the Sabertooth 990FX R2.0 is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization. The git repository for the firmware can be reviewed [https://git.15h.org/mrothfuss/coreboot-15h here].

=== coreboot-15h ===
{{Excerpt|Coreboot-15h|[[ASUS Sabertooth 990FX R2.0]]|hat=no|bold=1}}

=== Missing Features ===
* SeaBIOS does not respond to keyboards behind a USB hub.
* Hibernation and Suspend/Resume are unsupported.
* CPUs using the K10 microarchitecture are unsupported.

=== Flashing ===
To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. It is recommended to update the OEM BIOS to the latest version (2901) before switching to coreboot-15h, this will update the EC firmware to the latest version (MBECI-0006). The DIP-8 flash chip is located near the legacy PCI slot (labeled BIOS in the motherboard diagram). A 3.3V CH341a programmer can be used to flash coreboot onto the Sabertooth 990FX R2.0. When switching to coreboot-15h from the OEM BIOS, clearing the CMOS is required. The original DIP-8 flash chip requires the following flashrom argument:

<nowiki>
flashrom -c "W25Q64BV/W25Q64CV/W25Q64FV" </nowiki>

'''Clearing the CMOS'''
# Turn off the computer, disconnect the power cord and any powered peripherals (Monitors, USB devices, etc)
# Move the CLRTC jumper (located at the bottom of the board) to positions 2-3
# Wait 20 seconds
# Restore the CLRTC jumper to positions 1-2
# Connect the power cord
# Wait 2 minutes
# Turn on the motherboard

'''CMOS Battery'''

The motherboard requires a 3V CR2032 battery for reliable operation. Without a working CMOS battery, a two minute wait is always needed between connecting the motherboard to power and turning it on. This requirement is shared both by the OEM BIOS and coreboot-15h.

Socket AM3+

2026-05-12T02:06:26Z

Dodoid:

[[Socket AM3+]] is compatible with AMD Opteron 3000 series processors, and with the final two generations of AMD FX processors. Consumer AM3+ boards support all AM3+ CPUs, while server boards such as the [[H8SML]] are believed to support only the 3000-series Opterons. All compatible CPUs contain a single [[NUMA]] node.

Socket AM3+ was also designed to be backwards-compatible with the earlier Socket AM3 CPUs (Phenom II and Athlon II). However, these K10-microarchitecture CPUs are not currently supported by [[coreboot-15h]].

This is the news page - a blog for 15h.org development.

== Posts ==
<includeonly>__NOTOC__</includeonly>

{{NewsHeader|May 7, 2026|Introducing the 15h.org Blog}}
As of today, 15h.org now has a blog, of which this is the first post! It can be found on the News page at https://15h.org/index.php/News.

Currently, we operate three mostly-disconnected online spaces - this wiki at 15h.org, our Git forge at [https://git.15h.org/explore/repos git.15h.org], and our [[Matrix]] room. Of these, the best place to follow news and development has always been the Matrix room - most development work is discussed, planned, developed, and tested collaboratively over Matrix, and new releases, features, or other news are posted there in real-time.

If you're not in the Matrix room, however, following development is more disconnected. Development on the Git forge is done by several people across several branches, and much of the coordination for it is done through Matrix (rather than through Forgejo's built-in discussion features). The wiki aims to provide unified, always-up-to-date documentation - the flipside of this is that pages are created and edited "quietly" as new boards are added or new features are documented.

For coreboot-15h, the [[Coreboot-15h#Stable|release notes]] for each ROM build provide some documentation of development as it affects that board in particular. However, coreboot-15h itself is effectively rolling-release - we do not currently have a defined release schedule for it, and ROMs get built on a best-effort, board-by-board basis. "Versions" are really just the build dates and commit hashes used for individual ROMs - this is why some "versions" appear to exist only for one board.

The purpose of this page is to resolve this, by allowing news about development to be posted centrally (including for people not following the Matrix room), and to be archived once written (while keeping the rest of the wiki up-to-date). While the Matrix room will likely remain the best place for minor updates (and we continue to encourage everyone interested to join it), we plan to use this page for announcements such as new supported boards or platforms, notable improvements to coreboot or AGESA source, or upcoming community events.

As this blog is new, we intend for our next post to be a "catch-up" overview of development over the last few months. Stay tuned!

=== Why 15h? ===
Released between 2011 and 2014, AMD's [[fam15h]] (and its approximately-contemporaneous relatives, [[fam10h]], [[fam14h]] and [[fam16h]]) are the final high-performance x86_64 microprocessors lacking most of the limitations newer x86 platforms are encumbered by. In many cases, fam15h hardware can provide a performant, full-featured system, using entirely free and open source software. It enforces no firmware signing (allowing things such as [[coreboot]]), can be booted entirely with free firmware (including memory initialization), and it requires no privileged management coprocessor (such as the Platform Security Processor or Management Engine, found on newer AMD and Intel platforms respectively). Where a [[Board Management Controller]] is present, it can usually reliably disabled, or better yet, flashed with [[OpenBMC]]. On fam10h, even microcode is unencrypted and unsigned, and can be modified by the user.

Beyond their currently-unparalleled degree of firmware freedom for a modern x86_64 platform, AMD hardware of this era (in particular, 6200 and 6300-series [[Opteron]] platforms) remains a powerful and cost-effective option for many systems, especially under parallel workloads. Despite this, the comparative popularity of competing Intel processors during this era has limited the familiarity and uptake of these pre-Zen AMD platforms among many enthusiasts.

If you are looking for an x86_64 platform under your complete control, this website serves to demystify fam15h and its relatives, so that these systems can remain in operation well into the future.

=== What hardware was that again? ===
Robust support for coreboot on select fam15h motherboards has been developed and thoroughly tested at 15h.org. The current, production ready motherboards are [[KGPE-D16]], [[KCMA-D8]], [[H8QG6]], [[H8SGL]], and [[H8SCM]]. A handful of other fam15h motherboards have [[Motherboards|preliminary support]]. For these motherboards, the [[Bulldozer]] and [[Piledriver]] microarchitectures are supported by [[coreboot-15h]].
