Here are my specs:
Q6600 B3
eVGA 680i
4GB Transcend PC-6400 DDRII Memory
Vista 64 Ultimate
AC Freezer 7
Anyway, my motherboard could overclock my old e6600 to 3.35GHz at stock voltage and 3.6 with a modest vcore increase.
I have since sold my e6600 and transferred my q6600 B3 stepping CPU in. At first, I could not get beyond 2.7GHz, despite increasing the vcore up to 1.55v. And trying almost every combination of 6x, 7x, 8x multipliers and different FSB speeds. The computer will overclock to 1199 FSB with default vcore (around 1.22v in CPUZ), but would become completely unstable at 1200FSB despite increasing the vcore to 1.55v.
Anyway, after doing some research, I've come to the conclusion that it must be my board as others with the same board have experienced the same problems. I had thought that I was doomed at 2.7GHz, but I thought about trying a 1333 FSB BSEL mod just on the off change it would work.
Unfortunately, it still would not boot at 3GHz, but I was able to overclock up to 2.8GHz at 9x multiplier without a vcore increase. But again, anything beyond 2.8Ghz (despite increases to the vcore) and the system is unstable.
Oh and another thing, I also flashed between the various BIOS (did more BIOS flashes on this motherboard than all previous motherboards I've owned combined). And found that only the P31 & P32 BIOS (which are supposed to help overclock 1333FSB chips better) were the only BIOS that allowed for the 100MHz overclock increase. Using P29 led to failed results.
Anyway, if anyone has anything to add to help me get to 3GHz or beyond I'd appreciate it. But for those who are like me, I hope this post helps.
