I tried stress testing the GPU's again and ran DNET on the 3 GPU's for 18 hours straight without a single crash. I also tried running BOINC with my anti-virus turned off and it crashed within 20 minutes.

I guess I could try disabling hyper threading but then I'm loosing half of what my 980 can do :(

I also tried disabling that C1 something setting that was suggested on the other forum and that didn't help.

If I run BOINC with the GPU's disabled it can run all 12 cores of the processor constantly without a BSOD.

Like I also said before, it's strange because my XPS system with the Q6600 and 2 GTX 470's runs for days on end without issue.

You are not losing what your 980 can do. You system should be dominated by the GPU's. I have the same processor, and although it worked fine at Einstein with hyperthreading, it would not work with SETI, regardless of clock speeds. Turn off hyperthreading, and see what happens. It seems to be the combination of some 980 chips, and multiple Fermi's running SETI. Look at my RAC, hyperthreading is shut off, and I am running only two GPU's. Your's should out perform mine with 3 GPU's. It seems that in this situation, hyperthreading is slowing you down, not speeding you up. My system was crashing constantly until I turned off hyperthreading. Your CPU crunch times will decrease, and you can get more clock speed to make up for the lack of the 12 CPU threads. It is certainly worth an experiment.
