Small FTT's run fine, Blend however BSOD's the hell out of my system in a couple of minutes.
Blend is the only real stability test for Sandybridge. It pushes mem and memcontroller (built-in the Sandybridge) Even if you're stable in Small FFT's, Linpack/IBT or OCCT, does not mean you're system is stable. It can crash when you're gaming or doing other somewhat heavy stuff.
If you're 12 hours + stable in Blend, you can be pretty sure you have a stable system.
Also, I highly recommend Disabling C3/C6, even if others say they are fine at Auto. They are not in my system, at least with the latest 2001 bios for my P8P67 PRO. If these are at Auto or enabled they can cause Idle BSOD's or freezing.
Edit: If you wanna proof to yourself and others, true stability, then head over to the  The Sandy STABLE Club 
and read the OP carefully. Then make a run for it.Edited by turrican9 - 10/8/11 at 8:07am
