GPU overclocking problem/help

Hi there,

I have an on going problem that for the life of me I can figure out.

Untill 2 weeks ago I had no problems OC'ing my GPU now I can set the OC, Benchmark the hell out of it and its fine untill I play a game (MW2,DIRT3,BFBC2)

I am 100% sure it has enough Vcore as it was fine for months, I've upped it to 1.063 from 1.050 to be sure and the problem still exists.

When gaming after 20-40 minutes the screen will go black for 1-2 seconds GPU fans power down to silent for those 1-2 seconds then its fine strait back into game and GPU fans roar up again and I carry on playing but i've lost my OC in MSI Afterburner, Though my Fan profile is still intact.

Thats what randomly happens during gaming, To regain my OC I have to close Afterburner and open it again.
I have no other GPU oc;ing software installed that could be interfering, Temps are staying ~78C when oc'd.

Any help really appreciated or a good alternative to MSI Afterburner if there is one. :confused:

Cheers

e2a: problem exists on all the drivers i've tried (the latest 4 from nvidia)

Thanks for the reply

, I gave memtest ago and all came back fine.
After a lot of playing around in MSI afterburner I have now realised it will do the same thing with just a 1mhz OC, Stock = 800mhz and its fine. If I oc at all even by 1mhz then the above happens pictured in Afterburner.

The cards showed no Artifacts that im aware of, When it dorps out for a second reverting back to stock clocks during gaming like in op post the screen just goes black for 2 seconds then all back to normal in game, Just minus the OC of course.

I have tried the spare 2 PCI-e connectors from my TX750 and its still the same, I think a branded 750w PSU is more than enough for a single gpu machine, Even if OC'd?

This is driving me bonkers, Especially now its doing it in BF3 BETA where I'd really appreciate the OC to stick..

Sorry to moan a lot

I gave it a go, uninstalled then removed all registry entrys related to msi afterburner, Rebooted and then reinstalled.
It was fine for about 10 mintues, Then black screen for 2 seconds and back to game but OC has been lost.

Is it worth reinstalling OS?

I really thought msi afterburner would work ok considering its an msi gpu..

Is there any alternatives I can try to see if has similer problems?
