Hey guys.
I recently bought a new MSI Radeon 6950 after reading great reviews, particularly on how easy it is to flash to a 6970. When it arrived I installed it fine, Windows booted up and everything seemed to be working.
I then flashed the BIOS to unlock the shaders, and again everything seemed to work fine. Finally, boosting the power in Overdrive seemed to produce no immediate crashes.
However, I'm getting a very strange problem when playing games (and so when the card is under stress, I suspect). After only a few minutes and probably not even that, my screen will split down the middle. It's as if it has been pulled through the other side of the screen; my left hand side switches to the right, and the right switches to the left. The "split" is not always in the same place, but it always has the same effect - as if the screen has been yanked across. I have noticed on one occasion that the screen turned to garbled lines, but alt + tabbing back into Windows fixed that immediately (but not the split screen, which happened at the same time).
I thought maybe this was an Overdrive issue, despite keeping everything within normal limits, so I turned that off and left everything at its default power. The problem still occurs.
The strangest thing is that by enabling or disabling Overdrive (whichever is the option not active at the time) the screen split stops, at least for another minute until it reoccurs again. But enabling / disabling will get rid of it again.
Is this a heat issue? Even on its default settings my card is doing this. I doubt it's to do with my case, as prior to this I had a 4870X2 in the same slot and that never once suffered from heat issues. I've a pretty decent case and plenty of fans, too, so without being overclocked there's no way this card should be overheating in normal conditions.
Thanks for your time!
