Overclocking 7850: Get BSOD whenever I slightly raise Voltage

post #1 of 7
Thread Starter 
Hello everyone,

I've been trying to OC my GPU to 1200/1250 with a voltage of 1.1V with Trixx.

I've been finding that anytime I try to touch the voltage, the video card becomes very unstable. Current'y I am running stable at stock voltage 1000/1225 and it seems to run fine. Anyone having any similar issues with their XFX 7850 DD?


Stable:

Unstable:

So is it just the card or am I doing something wrong. I've tried voltages in between stock and 1.1 and it's still super unstable.

I get the following BSOD:

Can anyone help me out?

Thanks! thumb.gif

I had a similar issue. Pulled my hair out trying to figure it out. I think it was conflicting programs trying to alter the clocks or mess with the drivers. I installed the beta catalyist drivers and its fine now.

Edit: also increase the power percent slider (that last slider) to the far right.

The board power Li slider? Also, do you just use CCC or are you using Trixx, or Afterburner?

EDIT: OK, I did what you said and made sure all previous registry entries of MSI Afterbuner were deleted. I restarted and ran a benchmark with the unstable clocks/ voltage. I got a little further than normal, but the video driver crashed halfway through and I was able to stop the benchmark software before it bluescreened. The drivers recovered before my PC crashed.

Am I correct in saying that this is where tweaking the OC comes in? Or is the GPU behavior strange? I've never had a stable OC on a GPU with voltage tweaking.

I'm not sure. I'm having difficulty with mine as well. I finally got to 1150 on the core and 1550 ram but that's without any voltage mods. I plan to look into the options to add voltage to it later.

Yeah, I'm thinking about pushing the clock a little higher with no voltage bump to see what happens. At this point, only small nudges in GPU/ memory clocks is all I can do. Good luck to you! thumb.gif

Bump.

Anyone have a good, stable clock and voltage I can try with this card to see if there's still an issue?

I still think it's a driver issue. Try removing all cases of drivers, oc programs, then get the beta drivers installed after restarting.
