My Opteron 148 is at 2915MHz and 3DMark05, 12 hours Prime95, and SuperPi stable at 1.450v. Idle temps are 25-28C and under load, 35C max. My RAM (Mushkin eXtreme Performance DDR500) is running at 208MHz on a 333MHz Memclock divider with the timings 3-4-4-8 I believe. So I still have plenty of voltage room, my RAM isn't holding me back, and my temperatures are awesome. At cpu frequency 273 (3003MHz) I can pass 3DMark05 and SuperPi, but I cannot seem to pass Prime95. I have raised my voltages to everything up to 1.50v, but still, no Prime95 pass. I could go to 1.55v, but would that make any difference since I am stable at 2915MHz with only 1.450v? Basically what I'm asking is if I've reached this CPU's max or if there is anything else to do?
