Ram is: G.Skill Extreme Series 2GB (2 x 1GB) DDR 500 (PC 4000) Power supply is OCZ PowerStream 520 Watt, I just mention it because this DFI mobo is quite picky about power supplies. This power supply is the best for this DFI board. The opteron 170 should do between 2.6 and 2.9, and the ram practically guruanties 2.5 but can usually go further up. I decided against some more expensive OCZ or Mushkin ram because there were 3D problems reported with a certain batch of them; they could do what they should, but couldn't overclock. The G.Skill should be fine overclockers. Regards, Dagh Nielsen
