I have a Dell PowerEdge r730 with 2 cpu, 2 psu 1100w and I got the proper gpu cable 8pins EPS that I verified with the multimeter. It is plugged in the right way and I go get good power on the yellow wires. I installed every drivers I found and did the registry shenanigans to have it in wddm mode etc but it always fails with:

This device cannot start. (Code 10)
Insufficient system resources exist to complete the API.

That server is using Windows Server 2022. I used to run a GTX 1070 Ti in there (with the correct cable which is different) and it worked A1

Please HALP !
