Thread Starter 
Ok im trying to get my i7 930 stable @ 4.ghz but no matter what i try prime 95 crashes after 2-3 hours blend. i get a 0x0000124 bsod. i know its a qpi/vtt related but even with 1.4V qpi it bsods. my vcore is at 1.3250.

info
BIOS Settings (ATK)
CPU PLL1.880 V
CPU Voltage1.32500 V
ICH PCIE1.500 V
ICH1.200 V
IOH PCIE1.500 V
IOH1.140 V
QPI/DRAM Core Volt1.35000 V
CHA CTRL0.500 X
CHA DATA0.500 X
CHB CTRL0.500 X
CHB DATA0.500 X
CHC CTRL0.500 X
CHC DATA0.500 X
BCLK Frequency192.00 MHz
CPU Ratio21x

what do you guys suggest. i tested my mem with memtest86+ for 8 hours no errors. Temp are fine to, 75c at full load 39-45 idle. added cpu-z screens, and 4 recent dmp files.

QPI/VTT voltage is very tricky, if you put it too high it will BSOD as well - I had to finally set mine to auto to get it to pass Prime95 for 24 hours

What have you been doing to OC? Are you trying to just do a quick and dirty to 4.0 or have you been working on this incrementally?

Yeah I would think so. Vdroop and such enabled? Have you tried shooting the middle and going with 1.325 on the QPI/VTT?

vdroop is disabled, yeah i tried everything from 1.250 to 1.4 qpi

though i forgot to tell, i did pass ibt 25 passes at max, maybe prime fails due some driver incompatibility?

Gotta be something with the QPI/VTT with that error. IBT isn't that intensive of a test. I got my 930 to pass it several times and then got failures on p95 and linx.

Try lowering the PLL a bit. Also what's your DRAM voltage at? 1.65?
