I've got my Q6600 at 1.3825V at 3.5GHz (9 x 389MHz).
Works great for me at 23-27C idle and 52-54C using Large FFT's in P95. Blend isn't the higher heat - so that isn't accurate to me. I also run a ten cycle IntelBurnTest v2.40 and that passes too (but can get me to 62C).
I'll try to get...
All these temps are on Prime95... with Blend or Small FFT. What about Large FFT or other programs?
What about IntelBurnTest v2.4? I consistently had temps differentals of +8 to +10C between P95 and IntelBurnTest on my Q6600. I'm running it at 3.5GHz (2.4GHz stock) and I'll get 62C on...
