Well, I thought that I had a stable overclock. I was running prime for 8 hours, no errors. So, I decided to give IBT a shot and got a BSOD almost right away. I was running with loadline disabled which I never had any problems doing with my wolfdale. Vdroop is MUCH bigger with my quad, 0.07 from idle to load in prime. Even worse with IBT. I had to enable Loadline or else I would have had to run 1.43 idle just to keep my VCC at 1.33 in linpack load. I noticed that my quad does draw more than my dual at similar voltages and clock speeds. Is it normal for vdroop to be that bad with a quad?
