I am also getting the same error:
Everything is at stock/default.
EVGA X99 Classified
Core i7-5960X
GSkill Value 4x8GB DDR4 2400 RAM
CORSAIR Hydro Series H100i CPU Cooler
Corsair AX-1200 PSU
EVGA GTX 780 ACX
Samsung 850 Pro SSD
Installed Windows 8.1 from scratch with the new system and everything is patched. Memtest did not find any artifacts. Furmark for 25 minutes and the GPU temp did not raise above 72C. LinX 20 passes with max cpu temps around 51c.
The crashes usually come when the computer has been on for more than 24 hours and I'm playing a game. I have three monitors (2x 1080p dvi & hdmi, 1x 2560x1600 dvi) if that matters. In diablo I get really poor framerates (10-15 fps) most of the time, while rarely I get 150-160 fps as expected. TitanFall won't even run for some reason. Loaded up HAWX-2 for lulz, and my last crash happened while playing (although, I was getting decent frame rates).
The corsair PSU & GTX 780 came straight out of my old x79 build that was rock solid for years @ 4.3ghz. And now I miss it... This is not just a gaming rig, but also my workstation and I have lost work multiple times due to crashes. Very frustrating.
This is far from my first build. In my experience, the evidence suggests a bad board. My next guess would be something to do with the Samsung software since I had one crash that had to do with SamsungRapidDiskFltr.sys (which is now uninstalled). I might try reloading nVidia drivers since that is one of the few things I have left to try on my own.
Would love to hear if you have any updates.
