[SOLVED] Help with dual graphics cards

[PaX31]

So Recently I built a new PC. My old system had a 1080TI and 1060 running together had my main monitor on the 1080 and the others on the 1060.

So when I built my new system I got a 3090TI and a 3050 the plan was to do the same thing however I can not get them both to run at the same time now. Before when I installed the second card it was plug and play but now there seems to be a driver issue but both cards are running the same driver versions.,.

Any helpful hints in being able to use both cards at once?

Why the second card at all? Ever since Eyefinity came out GPUs have been excellent at multi monitors. Honestly I'd just plug everything into the 3090TI and save the electricity of not having to run the 3050.

As for why, not sure. What motherboard are you using? PSU? How are the power plugs and monitors attached?

Several games I play will cause the other monitors to lag out with movies.. Ark still runs at 95% GPU even on a 3090TI


ROG STRIX Z590-E
17-11700k
VENGEANCE LPX 64GB
Hx850 PSU


3090Ti is pluged in using the supplied cables 3050 is PCIe cable
Monitors are using DP and HDMI

Wont let me post a picture of the error im getting but it says

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

The I/O device is configured incorrectly or the configuration parameters to the driver are incorrect.

What's the story on the 3050? Where did it come from? Does it work all by itself?

Both cards came straight from EVGA. Both work independently but cant get them both working at the same time.

You're gonna need a more powerful PSU.

Absolutely. an 850W PSU is the MINIMUM requirement for an RTX 3090ti. Real world will often need more to be stable consistently and reliably. You are then adding a second GPU to the system. I would get a much stronger PSU if you intend to use both GPUs at once.

Yha jsut sent back my 1200W corsair.. waiting on my replacement

Lose the RTX 3050.
You're running into driver conflicts because the RTX 3090Ti has it's own set of drivers that do not support any other card.
RTX 3090Ti Driver Download Page - 512.16
RTX 3050 Driver Download Page - 512.15

To use dual graphics cards, your computer needs AMD or Nvidia technology that links the cards to produce a single output. The AMD graphics technology is CrossFire and the Nvidia technology is SLI.

well thats jsut not true.. I was running a 1080 and 1060 in my last build and it wasnt SLI

It shouldn't be the different driver either. The only modern Win OS that could load only one GPU driver was Vista. You haven't given us full system specs, but I'm assuming you aren't using that. Otherwise you can load and run many GPUs and drivers for them. I've ran ATI and Nvidia cards at the same time. And as you pointed out, as long as you don't try linking them your fine.

Does the 3090TI work with either of your old cards? I don't think it's a power issue because it doesn't work at all. If it was a power issue it would work until you put a load on it?

There was always the capability of running dual cards in a system; long before SLI/Crossfire became mainstream (and has since died). The trouble back then was that the drivers often conflicted with each other. That is no longer the case.

Yha im win 10pro
I have not tried any other card i will get my 1080TI and see if that works.

Since they use the same driver package, try the 1080Ti with the RTX 3050.

It was in fact a driver issue.. Heard from someone that the driver 512.16 was "proprietary" drivers new ones drppped today and all the 30 series are matching and works liek a charm now.
