Fah-gpu keeps stalling

Here's what I would try if you already haven't. Although maybe obvious it seems to work more than you would think.

First of all What other settings are you using? What priority etc..

Maybe try completely removing GPUv2 and possibly drivers for ur card.

Can you game for 1.5+ hours straight?

I'm using pretty much all the stock settings for folding.

What exactly is GPUv2? I did just update to 9.11 drivers, though. I'm trying Fah again now.

Yes, I can game for extended periods of time without crashing.

It turns out I had been using the older version of the GPU client, so I downloaded GPUv2 and tried that. It works, but it's EXTREMELY slow. I get 20-30 iter/sec which is abysmal. Do I need to uninstall the previous version first or something? I had the console version.

What are your temps at while folding? GPU/CPU

yes uninstall all versions and then install gpuv2

Ok so I installed GPUv2 in my other OS (7 Beta 64-bit) and updated to 9.11 drivers... It seemed to work well at first, but then after around 2 hours my PC just shut down, no BSOD or anything. My clocks are 815/1075 at the moment. I tried using Rivatuner to lower the clocks but GPU-Z reports no change afterward. Perhaps 9.11 drivers don't play nicely with Rivatuner yet... I'm going to try reverting back to 9.8 or 9.9, then try again.

Oh, and my temps are just fine. CPU temps range anywhere from 35C to 50C (only one core is being stressed), and GPU temps remain at or below 65C.
