So, i am steady at 4.0ghz 12hrs prime stable (will go for 24, just needed to get work done), and have all my base voltages locked in off of Auto... even the Advanced ones. I have read up on Clock Skews (Normal for IOH and 200ps for CPU) and i have read up a little on CPU Differential Amplitude... I understand that it helps the CPU signal "yell" louder above the natural increase of noise at the higher clocking frequency's to help stabilize signal so nothing gets lost in the noise. But is there such a thing as to high of a CPU Diff Amp? I locked mine in at 800mV, but if i set it to 900-1000mV would it kill anything? cant seem to find an answer.
I only ask, cause once i raise my Bclk 9mhz from 191 to 200 (for 4.2 @ 200*21) i can post into windows and find some what a stability loss even with a lot of added voltage.... 1.31v for 4.0 and a bump to 1.35v for 4.2, (it could also be my QPI, that is at 1.27500 which is fine for 4.0).
long story shory, who plays with CPU Diff Amp? and really knows it inside and out?
off topic but while i am hear, i know a BSOD 101 is Vcore and 124 is QPI/Vtt, but what about the weird 7F, A, 9C, and all those weird 1-2 letter/number combo BSOD's, never experienced those with my C0 step chip, just this D0.
