Screen split vertically while gaming

[Rhezuss]

Hey all, weird problem yesterday occured while I was playing Skyrim.

I was playing for like 4 hours and all of a sudden my screen split vertically in 2, n ot in the center and I could move my mouse cursor to the left and it would appear on the right half...

I could still control and click things so I exited the game. On desktop same problem. I had to reboot and all went back to normal.

What could have caused it? Artifact? OC? Overheating? Game bug?

BTW, I have the 6950 unlocked (no BIOS, just with the switch) and OCed to 875/1375 @ 1.175v.

First time I saw that or had an issue with the card...well is it the card or driver or something else? For other infos see signature.

Thanks for your help!

Game bug

is my guess.

I had this happen to me in BF3 Beta and FFOW when I was using an unlocked msi 6950 ref. -- I lowered my oc from 925c to 900c and didn't see it again.

Might as well do that, thanks!

Well if it was a game bug it would disappear when I exited the game?

I had the same thing happen on my HTPC, only that this happened on a different game (AC:Brotherhood) and on my primary display (TV). I also had to restart to make it go away. I suppose resetting the display mode (switch off display clone and back on) could have fixed it too but I never got around to testing it.

Are you running Catalyst 11.10? This only happened to me after upgrading to this version.

Yes 11.10 WHQL. Maybe a driver bug then.
I slightly changed the clocks on my card after reading some post about stable clocks for the unlocked 6950. I went from 875/1375 to 880/1350 on 1.175v.

Ran Skyrim all evening and nothing happened, game runs smoother...even smoother than before. Probably a placebo effect though.

Thanks for the feedback.

I'm inclined to think a driver bug indeed. I forgot to mention that this happened to me after enabling AMD Overdrive in Catalyst (and upp-ing the GPU core & mem clocks to the highest allowed). I'm guessing it's much less unlikely to happen at less aggressive or stock speed.
