OCZ is no longer in the PC memory business, but back in 2009 they were. The memory you have doesn't have XMP profiles. It has something that was marketed as Black Edition Memory Profiles (BEMP) that were accessed by using the unique AMD “OverDrive” (AOD) capability. BEMP works through AMD's Overdrive software, BEMP was exclusive to socket AM3 motherboards. One of the requirements: the system must meet the following requirements in order to enable the Black Edition Memory Profile feature: ◦790FX, 790GX or 790X AM3 motherboard with BEMP compatible BIOS revision You do have to manually increase the DRAM voltage to 1.65v from 1.5v on that memory.
