Either re-do OC without LLC or raise the Vcore till idle Vcore = current Load Vcore.
TBH i think i have tried this.
PC can pass Prime95 small, blend, large, OCCT 4.0.0, and IBT at 1.3500v in bios with LLC on. Have increased vcore to as high as 1.39 with no improvement.
Have also tried with LLC off. Even raising the vcore to 1.425v provided no improvement.
I'm actually starting to think it might be GTL references.
For my CPU to be able to pass large fft and blend in Prime95 the GTLs need to be manually tweaked. Core 1 in particular tends to fail P95 if its respective GTL is not around 0.830. Core 0 will also fail if its GTL is not around 0.825.
Currently started my entire OC again.
0.645 0/2 GTL
0.650 1/3 GTL
1.34v FSB (running a tad higher then what i believe it needs)
0.645 FSB GTL (i've read that its a good idea to sync this with the CPU GTLs?)
PC is now Prim95, OCCT, IBT, Memtest86, and 6 hours of PC gaming stable.
Perhaps its a case that although stable under load, the GTL needs to be tweaked a little more?
Is it possible that GTL could result in the error im seeing if they're to high or low?
If so, i'm thinking it might be a case of the GTLs are still a notch or two two out and thus causing some issues with the CPU.Edited by matthew87 - 11/6/11 at 4:57pm
