CPU/NB: 2.6 GHz, 1.2v voltage
I thought the voltages might be a bit too low, but it passed 10+ hours of each prime95 test, 2 full Memtest runs, and 20 IntelBurnTest runs on Maximum. Diablo 3 crashed once during gameplay though, and this never happened before. Is it even possible to pass all these stress tests and still not have stability in games? If yes, do you think I need more CPU or CPU/NB voltage?
Sadly I wasn't able to get Diablo 3 to crash again, and I don't have any more demanding games installed at the moment.
I actually had the same issue back in the day when I was first overclocking my phII 955 on my asus m4a88td-v evo. I was able to get things prime stable for 12ish hours but under any real world use it would fail and BSOD or lock up. Raising the vcore up a tad solved the issue and I made sure I was able to run prime95 24 hours without crash.
to give you a general idea I had my cpu at 3.82Ghz @ 1.37-1.38v under load. And if I remember correctly that amounted to a BIOS setting of 1.35-1.36 with LLC enabled. My NB I had clocked just under 2700Mhz at a cpu/nb voltage of 1.185(or something right around that) and cpu/nb LLC enabled with gave it about 1.2-1.22v under load. Those were my stable settings. Ill have to see if I can dig up any screen shots to help ya out a bit more.
Hope this helps ya out and feel free to pm me with any questions you have as well.
