I am new to overclocking and I just built a new computer, i will list spec's below. But I used the OC genie on my MSI MoBo and am stable at 4.5 for that. However; I overclocked my GPU after watching a youtube video on overclocking my same GPU and what i did was, I set my GPU clock offset to a +115, and Memory clock offset to a +55, using EVGA Precision X, then I overvolted it +12. All these things the dude did in the video and it was stable. So instead of running a bench or stress tests I jumped into COD Black OPs and started my gaming, it was great till it crashed. I then restored my GPU to its default and then after that I kept having my driver crash during valley benchmark. So i ran Farcry 3 and I saw the twitching, and stuttering, and also in Borderlands 2, however; COD Black OPs runs fine. So I uninstalled the driver that kept crashing an reinstalled it and now it ain't so bad, but the twitching, and stuttering are still there in some games and the FPS I was getting I don't get in them games any more. Did i mess up my GPU overvolting it? Is there a way to fix this? Did I mess up the default OC and now its not as stable? Should I mess with OCing it to find a stable point? Any and all help would be great thanks?
