6990 OC Problems

post #1 of 3
Thread Starter 
Hi,
Recently my PC has been getting BSOD and hard lock-ups, I wasn't able to run 3D mark11 past the physics test and can't play crysis 2 every time I do it gets stuck at certain parts I still hear the music but the screen gets locked up and have to manually restart. I ran memtest I even took one stick out as I thought it might be the timings.
One really bizarre thing that happened was after I couldn't pin point the problem I reformatted and as I was installing win 7 I got the BSOD after the the drives where erased, so I tried a second time and everything went fine. I was able to run 3dmark 11 fully it turns out that it was my 6990 OC when I put it back to default the game runs fine but when I put it to 1ghz and 1450mhz it hard locks the game but why now and is something in the card fried?
Also do you think I will have allot or trouble if I RMA it cause to install the water cooling block I had to make the bracket holes a little bigger so the screws can can fit.
Thanks

Your card is just unstable at those speeds. There is nothing you can do about it. You don't need a 1GHz core anyway. Just run a stock clocks, CF enabled and enjoy your games. Nothing on your card is "fried" so don't worry mate. I know your disappointed about the overclocking on your card but some 6990's OC much better than others, as with any computer hardware.

Hope this rests your mind mate. If you wanna try your luck at RMA then go ahead. Just don't tell them you had a WC block. Put the stock HS back on and hope they don't remove it. Then again, i really don't think you would win the RMA as the issue only happenes when you overclock.

Thanks for the response.
But how come I was able to stay at those clocks for about 3-4weeks and now all of a sudden it isn't stable?
I think it could be the video cards RAM is there anyway to test it?
If not I'll give the RMA a try and hope I get better luck with the replacement.
Thanks

EDIT: I tried running crysis 2 on stock settings and got artifacts
Guess I have to RMA and hope the bracket mod won't cost me $735
