Also, I know it's not a heat issue, becuse I use 3 fans + liquid cooling whenever I overclock it that much.

It varies much from sample to sample, in fact the stepping code at which time it was manufactured matters most I'm afraid. My Opteron 165 is a CCBWE 0550 UPMW and has both good samples that do 2.9GHz+ and some bad ones that tops out 2.7GHz or slightly below no matter cooling. Best Opteron 165 stepping for aircooling I know is CCBBE 0610 DPMW that runs up to 2.70 - 2.8GHz on stock volts in average and maxes at ~3GHz with 1.48 - 1.52v. You need to raise vcore sooner or later, I'm able to run up to ~2.65GHz or so with stock vcore 1.35v but requires 1.45v at 2.8GHz. You're right about that PCSX2 is very stressful for the CPU especially for dual core cpus with MTGS and DC mode enabled (could be considered as a CPU stresstest even

), temps go almost as high, maybe 1 - 2C lower than stress tests on both motherboard and cpu for me.
Anyways let's stay on topic, if you got hardware/overclocking questions we could rather discuss it in PM.
