Windows errors after overclocking?

post #1 of 5
Thread Starter 

Yesterday i did my first overclock (4.5 ghz @ 1.3V) on my i5 3570k and stressed tested it for about an hour useing prime 95, everything was good. then i went into WEI(Windows experience index) and it would either crash of give me another error, because a was getting other errors wtih windows even before i OC'ed i just reinstalled windows. so i did that installed all my drivers, ran WEI and it worked fine, and windows was running smooth. i decided to OC my cpu again, ran prime 95 for 2 hours all was good then i started installing some of my programs back and i was getting constant windows explorer crashes, browser crashes, WEI crashes. but never got a BSOD.

So what am i doing wrong here? temps are good, i know i didn't stress test very long but all seemed stable.

I used two diffrent overclocking tutorials and each time i overclocked i would get windows errors.

here are my specs.

Intell i5-3570k
Asus p8z77-v motherboard
8gb G.skill ddr3 1600mhz ram
Gtx 670 ftw
Corsair 750w psu

I never had all these windows problems before overclocking, i'm am assuming this has something to do with the ram.

Thanks for the help guys.

yep I have battled with the same thing up until the other day. WEI would crash and some say who cares about WEI but I reakon its a good test of an overclock. Try and bump up the voltage a bit on the CPU as I think it stops testing floating point (well mine did anyway) I am running 4 sticks of 4gb 1600 memory and the voltage fixed mine. I am now running 4.6 at the same voltage I had 4.5 with 1.35v in the bios and 1.27v in windows. thumb.gif

It's not just WEI, it's windows explorer, internet browsers, some drivers. They all start crashing after OC mad.gif

Another weird thing is that resetting bios won't fix it after OCing, I have to restore windows every time.

EDIT. You where right, even though the stress test was stable low voltage was causing the issues, thanks for the help

Glad to hear you have it sorted.

A good way to check for those edge-of-stable cases is to check the event viewer logs for WHEA errors. They tend to show up on Ivy chips when the voltage is just a touch too low, but still high enough to pass Prime.
