Beste,
Ik heb dit bericht rechtstreeks gekopieerd van een Engelstalig forum en had geen zin om het helemaal opnieuw te schrijven, daarmee dat het dus in het Engels is
.
Specs:
* Core i7 930 d0 @ 4ghz (1.25v, LLC level 2)
* CORSAIR CMX6GX3M3A1600C9 6GB KIT (3X2GB) 1600MHZ DDR3 XMS Triple Channel
* Gigabyte GA-X58A-UD5
* Corsair HX650w
LLC: level 2
Vcore: 1.25 v
QPI/VTT: 1.34 v
CPU PLL: 1.88 v
Rest: auto
memory multi: 8x
uncore multi (At the moment): 16x (tried everything from 17 to 20, first boot with 16 though)
So I successfully overclocked my core i7 930 to 4Ghz with an amazing voltage, but everytime I cold boot I get bsods (memory management 1A) and a lot of errors with memtest. After fiddling with some options I found out that the uncore clock ratio was responsible.
Whenever I cold boot and I change the uncore clock ratio the bsods and errors disappear. It doesn't matter if I go up one or down one on the multi, it just stops bsoding.
Right now I tried to go with 16, which shouldn't work as I've read that you need 17 (2x 'mem multi=8' + 1) for stability, but it's working fine.
It just baffles me that I get BSOD's EVERY SINGLE TIME I cold boot and they disappear EVERY SINGLE TIME I change the uncore ratio. Does anybody have an explanation for this?
P.S.: You might noticed I've set LLC to level 2, will I hurt the cpu if I do this? Because I get HUGE vdroop with it disabled (1.275 in bios becomes 1.2 under stress in windows
).
To recap:
Bsod's and memtest errors only appear after an overclock and when I start from a cold boot.
The problem only goes away when I change the uncore multi (changing timings, mem multi,... all don't help). After changing the multi I reboot and the pc turns itself completely off, start back up again and everything is fine.
Stock speeds with no overclock is fine also.
This is the first time I can't find what's causing it, it's the weirdest problem ever...
Best regards

Blijkbaar is dit voor iedereen een mysterie...
