F@H errors related to GPU

Bizarro252 · May 31, 2015

Hi!

I am running the latest edition of F@H and am having some issues I am trying to troubleshoot that only appear when multitasking while folding, and I would like to find a solution other than to pause folding when using the computer

I HAD issues where the graphics driver would hault and recover, but seemed to have fixed this with adding the TDRDelay at 10 seconds in registry, everything was fine for a few days but today I got an error I had never seen before, I was playing a game, folding, and alt-tabbed out to change music and the system locked up, a few seconds went by and an error pop up in the bottom right stated that the folding.exe (cant remember the actual name) had been denied access to the graphics hardware. F@H of course restarted the WU and then another error popped up saying now that Chrome.exe was also denied access to the video hardware.

I have been looking all over and can only really find multiple others than have had similar problems, but no fix.

Has anyone else encountered this? Wondering if I should diable TDR all together...

Thanks!

Unstable GPU overclock perhaps?

Perhaps, however I actually should have edited that in my OP... I put the card back to stock specs once I started having issues for testing, these errors are not happening at that speed. I will change that

This "can" happen. Especially if your doing some other video task and it is trying to take exclusive control of the GPU, which it sounded like that was what exactly was going on. I have't had that happen to myself, but can see it happening under specific circumstances, esp if something like hardware acceleration is enabled in Chrome.

FYI - I typically pause my folding when playing any of my games, just for optional performance int he game and so Just In Case or a crash, I don't bork the WU.
