*I don’t have the lite version, it’s the full version.

so should support 3 gpus.

Thanks guys.

Well, unhook the monitors. See what happens.

Oh, and are you connecting those GPUs using SLI connectors? Don’t do that.

Check in Windows Device Manager, and verify in the Display Adapters section that Windows actually sees all those cards properly. I would not be surprised if you see some yellow !’s there.

Tried without monitors hooked up to bottom 3 cards, and without quad sli bridge. Still says 1 gpu in davinci. All 4 cards are detected properly by windows (no conflicts or errors)
Also, all 4 cards show up in the cuda toolkit no issues there.

Could it be that resolve doesn’t support gpus running in x8 pci-e mode?

I would try pulling one card out and running 3 GPUs because with that board and the four cards you are out of PCIe lanes.
