    Default GA-P67A-UD3P-*B3* Intermittent V-droop problem

    Hi all, I have recently posted in the M/B thread about some issues I had with my UD3P, Now it seems I have another issue which I cant work out, Currently I am sitting @ a stable 4.2ghz @ a manually set Vcore of 1.31v, I have set this using the offset feature in Dvid as it helps keep my V-droop to 0.01v, therefore underload it shows as 1.30v in H/W Monitor and Easytune 6. Now when I first started testing my O/C for stability, everything was A-ok and I settled on a 24/7 O/C with a then vcore of 1.26 and then whilst browsing I got a random Bsod (error code 101, which means vcore too low), So after bumping the vcore up to 1.31v, I tested for stability using both Occt and IBT and ran 20 times on IBT and a 2hr run on OCCT and all was well until, Once again doing some browsing and then same Bsod "clock interrupt on secondary cpu" , Error code 101, The strange thing is, on both times that this bsod has happened, I have enabled C1E, C3/C6, Cpu thermal monitor and Cpu EIST, when they are disabled I dont get the bsod`s.

    So in my head I thought got to be too low a vcore with those settings, so I continued testing my system for stability with-out those features and what I found was that my M/B for some reason randomly undervolts by upto 0.07v for no apparant reason and when I check Bios it is still the same as I had set it, so I continue to boot to Windows and there as it should be is my 1.31v @ idle. What could be the problem here? I know my psu is sound as I have checked it for stability and had it tested, in idle conditions it sits @ +12.079 and under load drops down to 12.024 & sometimes 11.978, I know it is well with-in margins, So is it my Motherboard?? That is the only answer I can think of as I know the Cpu and ram are stable and error free ( run memtest on ram for 3hrs with-out error). Any help on this guy`s, dont want to have to Rma my mobo with-out knowing it is that for sure, thanks in advance.....Teejay.

    Are you using the latest bios for your board? Does your board allow different levels of LLC? If so what level of LLC are you using.

    You could try clearing cmos for 20 min or over night. Load optimized defaults and try again. Flash to the latest beta bios. Making sure to clear dmi pool data when flashing and load optimized defaults after flashing.

    Yeah sorry should of added that I am using the latest f4 Bios and loaded optimized defaults when I last cleared Cmos, As for LLC, On this board you can only enable it, Which I have done already, I have hunted high and low for a solution on the net and have yet to find anything remotely conclusive on this issue, I have also mailed tech support @ Gigabyte to see if they have a solution, though still waiting for a response.
