Actually it crashed @ 4.0ghz even I bumped the Vcore a little higher around 1.33V, but there's a limit I don't want to pass, so I just put it back to 3.6ghz with 1.2V to make sure it's stable and I overclocked my 2 GPU's a little more to make up for the PPD loss from 4.0ghz to 3.6ghz *note I gained some going from 3.2ghz to 3.6ghz*, both GPU's can neat up to 9600ish PPD on their own depending the WU's
The best test is everyday use :P
VMware SMP + 2 GPU clients + some browsing, music and videos.
I also took the time to reapply TIM on my GPU's which made them drop by about 10-15C, their temps stays around 64-65C @ 60% fan speed where I used to need 100% fan speed to get these temps, @ 60% they'd get around 80C's
San Aces speed @ 1920RPM +/- 30 RPM, proc temps in the low 60's/high 50's, cool PC and silent :D, should be all stable since I bumped the up to 1.188V.
Very happy with the results so far!
*It may not be fully stable, can crash in the night still, so far so good anyways! *
