Well guys, I'm done tweaking my opteron 146. I can get it to run at 2.7ghz on 1.488v. I'm cooling it with a Cooler Master Hyper 6+, runs at 38-42c idle, 52-57c full load. A little warmer than I'd like. This is the highest I can get it to run Prime95 24 hours stable. I'm running my OCZ 3200 Platinum Rev 2 on dividers, so it shouldn't be affecting things. Mobo is DFI n4 ultra-d w/ 623 bios. Should I be able to do better? I have the apparently famous CABNE stepping. Love this processor, but honestly hoping for just a little more. I can get it to run Super Pi at up to 2.9 and I can post into Windows at up to 3.1. 2.7 is where 24hr stability ends though.
