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.

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

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.

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.

Socket [[C32]] provides 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.

	[[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.

			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:
