[Tulû]

Tulu, I experienced similar things (different cores failing at different times), I bumpe dup my NB.. Where is yours at?

Tulu - seems like that cpu is going to be stubborn. You could try lowering vFSB back to 1.42 - 1.44v, and raise GTL's one 0.05x step at a time up to perhaps 0.75x.

I think you may need to just give it more vcore to get it stable at 3.4GHz, some 6600's just won't do it easily, pity about your hot climate though. Perhaps try 3.33GHz at the same vcore you are at now? I don't think you will get solid stability out of the GTL or vFSB adjustment, but you could possibly raise the max bootable/benchable FSB by a few MHz.

Tulu, try setting the AI Transaction Booster to manual and then set Performance level to 10.

Hey there

I hope today will be an error day for core1 , core2 , core3 not for core0.

@ jas420221 , NB is 1.34

@ Cryptik , will try 1.44 vFSB term , GTL REF 0/2 : 0.70 - GTL REF 1/3 : 0.680
I've tried 413 FSB with 1.37500 Vcore and was stable for about 100 mins. and was going on but i made it stop.

@ Pntgrd , will try to set Performance level to 10 .
