Haven't been doing this long enough to have common knowledge. But will also give IBT a try, thx.

I have had nothing but problems with that driver, revert back to either the 270.51 or 270.61, run your original overclock again and see if you get a bsod.

worth a shot. Can I get the old driver from Nvidia site?

I disagree. I think blend is the best for sandy bridge, and also think most of ocn would agree. Not trying to be rude or anything. Just want to provide the op with the best information available. If im wrong, ill admit it.

On the other hand, it is common knowledge that small fft and large fft do nothing for sb. You can pass 12 hours of small fft just to fail after 1 hour of blend

@ 4.6ghz, 1.35V my Prime95 temps were around 72 and IBT 76 but would BSOD after the 2nd run. If I were to push it any higher, I'd be in the 80c mark so I decided to drop it down to 4.5ghz @ 1.31 Prime95 stable. After 1 IBT run it BSOD again so I bumped it up to 1.315V. I stepped away for about 90 mins and it completed 20 IBT runs 76C, highest GFlop at 111. These were all run at Maximum level.

I'm hoping this fixes any stability issues.

*edit* and it looks like the voltage bump also fixed the display flicker problem. nice.

12 hours + Blend test is the superior stability test for Sandybridge. No doubt.

I'm not arguing one vs the other...but after 12hrs blend, it still failed IBT after 1 run.

Did you use LLC? Most of us who overclock with the ASUS P8P67/P8Z68 series use LLC at Ultra High. If so, Load Volts will be higher for IBT/AVX VS Prime95.

So If you're not using any LLC setting, or a very low one, the opposite could happen, and make IBT/AVX unstable. Even if this was true, your computer would never crash in anything else, as long as you where Blend stable. This is because nothing else, except IBT/AVX would drop Load Vcore lower than Blend.

This is just a backwards statement.
Blend consists of small, and large fft...

My 950 was 12 hour prime stable.
But when I once played Black Ops it gave me 101 BSOD
I was at 23 multi and turned back to 21.
