Am I missing something ? with 701 I did 3.66 for my Q6600 with 1.525 and memory at 1100 2.12v with PL07 , now , it is not stable at all

What are the best configuration for Q6600 ? or how can I go back to 701 from Windows ?
You can't period. Only way to go back to older bios is through ms dos flashing tool AFUDOS and you have to boot from MSDOS floppy/flash drive to do that.

You cant just dial in same settings when bios options are added. Clear CMOS, set CPU Clock Skew to 100 or 200ps. NB Clock Skew normal, and make setting adjustments. Bios to bios changes occur and you can't expect stable settings from one to the next to be the same. It doesn't work like that. Sometimes you are lucky, other times when major changes happen you arent.
