6950 problems?

post #1 of 11
Thread Starter 
So, I had a similar problem in october-ish, but it hasen't happened in a while until this week.

I'll start steam and play Skyrim ( or SpaceMarine) for a while. Then when I exit back to my desktop, I'll have little green dots (sometimes clustered in a checkerboard pattern) in random places around my desktop. Sometimes they're just all over, sometimes in just an area. I'll also have general fuzzyness and distortion; i.e. fonts aren't as sharp as they should be, small areas of screen tearing, etc.

The only thing that seems to totally fix everything is either re-starting my computer, or loading up a non-steam game.

I do fold on my gpu, but i pause F@H while gaming. My temps while folding never seem to get above mid-60's (on the gpu). I did run furmark at 1680 x 1050, 8xaa, post-processing on, and my gpu hit 90 deg. Furmark was running fine, but when I stopped the test the screen got really messed up, and i got a BSOD 0x3b.

My card is a refrence XFX 6950 that i've had for about a year now. I'm running the latest drivers (12.1) and the latest bios for my MB. The only O.C. i've put on the card is 840mhz with CCC. The o.c. on my cpu is pretty mild at just under 4ghz.

Any help or direction would be a god-send at this point. Thanks in advance.

Already tried that twice. I also pulled the card, cleaned it and the pci-e slots with air, and re-set it in a different x16 slot.

it may be a last resort, but a fresh install of steam, and your games, might be helpful

It does seem to be mostly with steam games (well, thats most of my games). I'll give that a try tomorrow and see how it goes. Thanks

Try to run everything at BIOS default (CPU, RAM and GPU) to rule out OC instability. Reset CMOS then load BIOS Optimized Defaults. Reset the XFX6950 to run at stock clocks too.

Well, I set my card back to stock, and re-installed steam and all my games. After an hour, I exited and had no corruption issues. I then ran Furmark several times and had no issues either. I'd like to turn the OC back on, and quite frankly I was planning on pushing it higher. Any suggestions on a good approach?

Sounds liek its artifacting, due to not enough voltage, try bumping the volts up a bit, should fix it. Once you find your highest stable OC make sure to bump it down a bit, dont want the hard working too hard! thumb.gif

It just seems odd that it would be artifacing when it's not under load. But I'll see if Afterburner can bump the volts. Should I just disable CCC totally?

no, leave CCC running and try bumping the volts slightly on the card, not a whole lot, just a little, and see if it makes a difference.
