GA-P67A-UD3P-*B3* Intermittent V-droop problem
« on: July 20, 2011, 09:40:07 pm »
Hi all, 1st post here, si hello to all @ Gigabyte,
I seem to have a issue which I cant work out and hope you guy`s can give me a helping hand, Currently I am sitting @ a stable 4.2ghz O/C @ 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.
