Asus 980 Gold SLI semi-random crashes win7-64

[Cobra Rampage]

Typically I do not ask for help but random crashes while running two Asus 980 Golds in SLI have stumped me.

Windows 7 with geforce drivers version 358.87

Hardware is
I7-4790k at 4.6ghz with Corsair H100i watercooler
Evga Supernova G2 1300w power supply
Asus Maximus VII Formula motherboard
Corsair Vengeance Pro 16gb ram @ 1866 xmp profile 2
2x Samsung 850 EVO's 1 tb SSD in RAID-0

The video cards are slightly overclocked but nothing outrageous and my gpu temperatures do not exceed 70c under load. CPU stays well beneath 55c temperature.

Crashes typically are immediate crash to desktop or a random DLL error, guessing from my video card drivers.

Any ideas?

Return gpus to stock setting and see if the system crashes

Through the trials of everything I could figure out I reinstalled windows 7 and experienced the same results.

Windows 10 was the next thought what do you know, no crashes and I was able to get 1,520 mhz boost clock and 7,950 mhz on the memory setting.

YMMV.
