Motherboard Components
Socket AM3+
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.
AMD Opteron 3200 and 3300 Series
Processors in the AMD Opteron 3200 and 3300 Series were designed with the Bulldozer (3200 series) and Piledriver (3300 series) microarchitectures and are compatible with the AM3+ socket.
