The ASUS M5A97 EVO2 motherboard was produced in two variants for prebuilt machines, M51BC and M52BC. The M51BC version is more complete; M52BC appears to be identical but with fewer components attached to the board. The M5A97 EVO2 is currently the smallest known FX AM3+ motherboard with both an IOMMU and ECC RAM support. The Supermicro H8SML is very similar, but supports only the Opteron AM3+ processors.
Motherboard Components
Socket AM3+
AMD Socket AM3+, also known as Socket AM3b or Socket AM3r2, is compatible with a subset of AMD Orochi processors. It is backwards compatible with K10 processors designed for the AM3 socket, but these are not yet supported by coreboot-15h.
Official Documentation
Processors
Orochi FX (Zembezi and Vishera) and Opteron (Zurich and Delhi) processors are compatible with the AM3+ socket. TDP ratings for these processors range between 25 W and 220 W. Each AM3+ motherboard has a maximum supported TDP for CPUs. For example, the Supermicro H8SML is only designed to support up to 65 W processors.

AMD 970
The AMD 970, also known as the RX980, is a northbridge used with AM3+ processors. It has a total of 22 PCIe 2.0 lanes; providing one x16 slot, one x4 slot, and two x1 slots. The x16 slot can not be bifurcated. The RX980 supports HyperTransport 3.0 up to 2.4 GHz. It is often paired with the SB950 southbridge.

AMD SB950
The AMD SB950 is a Southbridge chipset designed for Socket AM3+ and AM3 motherboards, specifically supporting AMD FX, Phenom II, Athlon II, and Sempron processors. Released to accompany the 900-series Northbridge (990FX/990X/970), it brings native SATA 6Gb/s support for fast storage and 6x SATA ports, generally offering high compatibility for DDR3-based systems.

ITE IT8721F
The ITE IT8721F is a highly integrated Super I/O using the Low Pin Count Interface. It provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, including H/W Monitor and Fan Speed Controller.
Realtek RTL8111G
The Realtek RTL8111G 10/100/1000M Ethernet controller combines a triple-speed IEEE 802.3 compliant Media Access Controller (MAC) with a triple-speed Ethernet transceiver, PCI Express bus controller, and embedded memory.
AsMedia ASM1042
The ASM1042 is a USB 3.0 extended host controller designed to provide two ports over PCIe. It is designed for high speed, low power data transmit, backward compatible with current USB2.0 standard and complies with Intel’s eXtensible Host Controller Interface (xHCI) Revision 1.0.
Realtek ALC892
The ALC892 provides ten DAC channels that simultaneously support 7.1 channel sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Two stereo ADCs and one stereo digital microphone converter are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies.
Renesas 9LPRS477D
The Renesas 9LPRS477D is a main clock synthesizer chip that provides all clocks required for ATI RD7xx-based systems using AMD processors. An SMBus interface allows full control of the device.
