I have had HPET disabled for the past month with zero issues, albeit I am running integrated audio. Perhaps with dedicated audio cards it may cause issues, I'm not too sure.
Forgot to mention, there is a way to disable EIST while maintaining downclock and downvolt, but it lowers DPC by 10ns:
Set OC By all cores
go into CPU Settings with the EIST and Turbo options. Set CPU ratio to auto
go back to OC By all cores and set desired speed
back to CPU settings: Turbo is now enabled and not greyed out
Disable EIST, Turbo should still be enabled and not greyed out.
^There's probably a simpler way to do all this, that's just what I did
I have not noticed any decrease in benchmark scores, no increase in temps it's actually identical in every way AFAIK besides consistently lower dpc, albeit not by a large amount, I wanna say 10-12ns lower.
Again, this is all pointless unless you're anal about DPC latency haha
As a sidenote, the reason why I have not been very active in this thread is because my board just.. works. I have my OC profiles set in stone and it's been months since any BSOD has occurred, back when I was determining my stable voltages.
As well, I am able to run my Samsung 30nm LV RAM at 2133 10-10-10-28 1.435v 1.025v VCCSA and 1.0625v VTT (however measured by DMM they are both at 1.04v actual voltage, due to my VCCSA LLC set to regular with manual voltage). I suppose the IMC on this sample is good, I'd love to get my hands on a 2400 CL9 kit but can't find the Team set anywhere =(Edited by Scorpion667 - 10/28/12 at 12:02pm
