Dedicated Dual GPU's - Disable One in Windows 10?

post #1 of 12
Thread Starter 
Hi all,

I have two GTX 960's running (non-SLI) that I use for CAD rendering. I also game on the same PC and was wondering if I could disable the second GPU as it's not needed for the type of games that I play. Any way of doing it in Windows 10? I'm willing to install a third party software if needed.

PC SPECS
MOBO: ASUS M5A99FX PRO R2.0
CPU: AMD FX-8320 @4.0ghz
RAM: HyperX 16GB DDR3
SSD: Samsung EVO 840 x2 (RAID 0)
GPU: GTX 960 FTW+ ACX+2.0 (x2)(non-sli)

P.S. If you're wondering why I'm not running them in SLI, it's because my rendering engine doesn't support it and I usually play MMO's that can run on integrated graphics lol.

Thanks!

I'm pretty sure if it's not onboard graphics you cannot disable it, also some high end motherboards have dip switches that allow you to turn off PCI-e lanes, but I think this is on the Intel side, for example the Rampage V Extreme. Otherwise, the only way to disable the second 960 is to remove it from the case.

That's what I was trying to avoid. I don't mind a restart but taking one of the GPU cards out everyday is a hassle, not to mention the possibility of damaging the card/slot. Sadly, I just checked my BIOS, and there's no option to disable a PCI-e lane.

You do realize that since your not running sli it will only use the first gpu without you doing anything right?

There's two easy things you can do in the nvidia control panel set your display mode to be one which only uses your primary card.

Second goto device manager and disable the second card and enable it when you want.

But again without setting up sli it will only use your primary first slot gpu by default and your second gpu will be idle. So it's already the way you want.

I wish that was the case. The reason why I disagree is because when I run both cards under load, the lights in my room start to flicker (no joke). That stops immediately after I stop the load on the GPU's. I never had that problem when running 1 card. Also, the flickering starts even when any game (even on lowest settings). Just so you have an idea of what my room is like. It's a big open space where the kitchen, dining room & living room are all open to each other. I'm all the way in the corner of the living room and the kitchen lights flicker which is on the opposite side of all this open space. BTW, my display is set to the main GPU.

I haven't tried disabling the second card so I'll give that a shot. Thanks for the tip.

Go download MSI after burner or EVGA precision X I guarantee that it will show your second gpu as idle if your nvidia control panel is not set to sli. Another way to do it is in the nvidia control panel find the game your playing or select global settings and where it says GPU's select Single GPU rendering or something to this effect for global settings to force 1 gpu always.

remove your SLI bridge if you have it on, should solve the possibility that SLI somehow gets enabled.

I tried both of those softwares and ended up keeping EVGA's PrecisionX16 since my cards are made by EVGA and I like the interface of the Precision more. You're right that the second card was, well "sorta", idle. Say 10 mins into a battle and the second card fires up a bit. I also noticed in precisionx that the core voltage is at about 80% for the second card at idle. I did as you recommended and went into Nvidia CP, selected my game and changed the CUDA GPU field to use only one of my cards. I haven't tested it in-game yet, I'll do that tonight hopefully. I disabled the second card in the device manager to see what it'll do. It showed the second card as completely offline in PrecisionX but idk if that's actually the case.

Removing the SLI bridge did help.

As for the flickering, even after all the tips and improvements, the light flickers much less but it's still there. It feels like I'm at the club. The PSU is like 5 years old now and I know that performance drops with time. It's a 1200W PSU and I doubt I'm using more than 800W at load. Even if the PSU delivers 900 reliably, it still should be fine. But it is possible that the PSU is overdrawing power from the power outlet? Have you ever heard of this happening before?

Glad to hear that helped, as far as the PSU, I can't speak directly on that, I know everyone will point out a PSU with that wattage is overkill but I'm not sure if that would cause an issue like this. You should ping up Shilka on it.

Overkill? No doubt! This PSU has been with me for years and has seen many rigs where the need for that kind of wattage was a must biggrin.gif

I'm just trying to stop the damn light flickering but I'm happy with the results so far so I won't bother other people into this nonsense. If the PSU is fine, then most likely it's the electrical wiring at my place. I don't see anyone running quad GPU's saying anything about the lights flickering at their place. I just have to live with it for now. Thanks again everyone for your help!
