Hey guys, I built a i5 2500k MSI HD 7870 system and built it back in November of 2012. I recently just started overclocking my gpu. I would use MSI afterburner, move the core clock speed up15mhz, run furmark for about 5-10 minutes, then play something like farcry 3 for another 20ish minutes. Then I would repeat. It passed the furmark test and i didnt see any artifacts. So today i had it at 1170 (original was 1050) and I tried to play Crysis 3. But when i tried to play crysis 3, my system bluescreened. I lowered it 15mhz and tried again. Same thing. Lowered it another 15. Then the game would crash and freeze. My computer would keep working though, after that i got a "display driver has crashed and has recovered" I lowered it again, played crysis 3 beta for a little bit, then it bluescreened again.
1. What am I doing wrong?
2. I assume this is from having clocks that are too high, but how did it get so high without me detecting problems? I didnt see any artifacts in furmark and FC3 ran like a dream?
3. How can I fix it?
I have GPU settings set back to stock to avoid further trouble. Please help. Thanks!
well for starters furmark isn't as good stress test it used to be only a year ago, mainly because new drivers can detect it and throttle the clocks/load to avoid overloading the card, basically the drivers treat it as a 'power virus'.
You could run Unigine Heaven instead.
Secondly different games put slightly different kind of load on the card, some are more demanding and/or less error tolerant...
Ok, I don't want to play with the voltages, I just want to know why it keeps blue screening. I'm at stock right now, would you advise that I retry with Unigine Heaven and Crysis 3? I'll wait until they release the full game w/a driver, but It doesn't make sense to me that the clock speed of ur GPU can crash some games. Thanks!
