Only one of my cards is using 90%-95% load and the other one sits at 5%?

I have two GTX 780s in SLI (with bridge of course) and I've noticed in multiple benchmarks that only one is being used for the benchmark and in any number of my games. When I built my computer, I put one card in, installed the drivers, then plugged the other one in. Did I do that wrong or something? I'm also running an MSI Z87-GD65 Gaming MoBo

Is SLI enabled in the Nvidia Control Panel? At least for mine, every time there's a driver update, I have to re-enable SLI.

Jesse Barth · Jan 28, 2014

Yes its on in the control panel. Still not sure whats wrong

Whatever program your using to monitor the GPU Usage, Have you updated it to the latest version?

Other than that, I would try reversing them in their slots. In other words, Put bottom card on top and top on bottom

Switched the cards around and still the same thing. Also checked and all 3 of my GPU programs are up to date

Some games does not support SLI. which means, only 1 GPU will work, and the other will not.

I've got about 50+ games ranging from BF3 to oldies like Railroad Tycoon and none of them run in SLI...unless I've got super bad luck I'm pretty sure it's not my games lol

Jesse Barth :

I remember I once had a problem with SLI.

I had to install the drivers after the other GPU was installed. Which took me some weeks to realize >.>

Because if you download and install the drivers for one GPU, and then you install the other GPU. Only the first GPU will have the drivers.

I was thinking that actually
Is there a way I can somehow Re-Do that process?

Jesse Barth · Jan 29, 2014

Nvm found it

Blubberykollis · Jan 29, 2014

Jesse Barth :

alright.

Just re-download the drivers for your cards.

I use "auto-detect drivers"

It's pretty helpful if you are using SLI.

Jesse Barth · Jan 29, 2014

Alright so I did all of that and it's reading my first GPU at around 50% load instead of 95-98%. Second one still says nothing

Blubberykollis · Jan 29, 2014

Jesse Barth :

hmm.. Could you tell me all your specs?

RobCrezz · Jan 29, 2014

How do the benchmarks look? Maybe the reporting is just wrong.

Jesse Barth · Feb 2, 2014

Figured it out I went into the Nvidia Control Panel and went to "Manage 3D Settings" and got it working from there

Jesse Barth · Feb 2, 2014

Thanks all for your help

Blubberykollis :

Really?

Every SLi rig I've seen and used always detects the second card and installs the driver for it and as they use the same driver there is no way that only the first card can "have the drivers".

Well, that happened to me when I installed GTX 680 SLI for my friend. The other GPU was not found 'til I installed the drivers once again.

Only one of my cards is using 90%-95% load and the other one sits at 5%?
