Help Needed GPU crashing computer

Hi Folks,

 

I've been having some issues. If I run my computer with my SLI Enabled it works fine in some games but in other it runs for a minute or less and causes my computer to hard crash. I went to gpuz to monitor my system and it looks ok to me. If I take them out of SLI I never have a problem.  Both of my cards are water cooled and never hit super high temps.

 

What I've tried -

Power settings in Nvidia Control Panel

Windows Power Settings

Full Driver Wipe

Windows full reinstall

 

Specs :

2 x 1080ti

AMD THREADRIPPER 1950X

64GB DDR4 2733MB

1200 watt Corsair HX

Spoiler

I7-5930K | Asus Rampage Extreme X99 | Corsair Dominator Platinum DDR4 16gb 2666 | Corsair H105 | Corsair AX850 | GTX 1080| Corsair 900D | 2x Acer Predator 35" ultrawide | Corsair K70 | Corsair M65 | Sennheiser HD558 | Red/Black/Platinum Color Scheme | 4tb of SSD Raid 0

Try:

Test with furmark

Remove a GPU, use just one to play games, and then switch to another one

 

I think something else is hitting high temps

If it is auto rebooting it is likely either CPU temperature or power supply collapse. 

 

You can check CPU temperature by monitoring software.  You can also open your case side panel to reduce the temperature which might delay the crash.

 

If it's voltage collapse you can somewhat test this by removing one 1080 Ti and seeing if the system runs without problems.  By taking out of SLI do you mean taking one card out or disabling SLI? I'm not that familiar with SLI power draw when enabled/disabled.
