This motherboard supports AMD AM3+ multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransport 3.0 based system bus. This motherboard also supports AMD CPUs in the new 32nm manufacturing process. The new ASUS EPU - the world's first power saving engine, has been upgraded to a new 4-engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time.

Q: Hello i am interested in purchasing this motherboard but wondered if you could clarify something for me the line ni the specifications: '***Due to CPU Specification, AMD AM3 CPUs on this motherboard support up to DDR3 1333MHz' does this mean that if i used this CPU: AMD Athlon II X2 250 3.0GHz Dual Core Processor that the memory speed would only work at 1333 even if i installed RAM running at 1600Mhz?
Answer by CCL on 22nd August 2012
That is correct, to get over 1333Mhz you would need to be using an AM3+ processor. -Danlevan
