So I dialed back to my 12 hour prime stable 3.9GHz setting same freaking problem, not stable! Getting frustrated at this
Ok well for 445 FSB PL8 on the 266 strap I run my vNB at 1.27225v, NB GTL Ref on auto. However because you have a quad obviously you'll need more voltage for stability. I know you know what you're doing but what have you tried to regain stability other than down clocking to 3.9GHz?

I have had similar instability over the past few days, and actually needed to increase my GTL's a little to regain stability.
