[SOLVED] I have two 980Ti graphics cards. How do I only use the second card, and disable the first card, without taking them out?

[sjain]

Fitting the PCI screws was an utter pain. Wonky almost every time.

 

How can I disable my first GPU, so games only make use of the second? I've tried SLI Force alternate rendering, and disabling SLI as well as plugging my monitor into the second GPU. Any ideas?

 

I would have thought this would be easy, with software. Can't find anything on Google.

 

I've also tried removing the power cables out of the first GPU. The PC doesn't post.

Why do you want to disable the first card?

turn off sli

then turn off computer , plug monitor into second gpu , then turn the computer back on

In any case , the monitor must be plugged into the gpu that you want to use alone

Does it matter?

Guess not. I'm just confused as to why.

If you're going to disable SLI, why not use the first card?

kinda,

they are identical gpu's so there no reason to not use the primary gpu as your primary output

unless you are purposely trying to not tell us what the actual issue is and are instead trying to solve it by using the second gpu

make a type 1 vm and isolate the 1st gpu and not use it

I'm not disabling it permanently, I am testing to see if my thermal paste reapplication has improved temps. SLI interferes with that

use gpu-z , it displays both gpu temps separately even if sli is activated or not. you can watch/log the temps of either gpu

[sjain]

its solved, after three reboots. just plug monitor into second gpu.

 

but another issue cropped up
