like i just posted in some other thread for c2d i only use blend .... small and large fft can be run for hours even stoped at 20+ h and blend would only last not even 10 min, and only vcore would solve it...first i was thinking mobo/ram voltage or timming but none of it helped only vcore got it stable

this is on 4 e6600, x6800, qx6700 and P5Bdlx and also my friends P5Wdh and his 6600
