GPU Passthrough error code 43 | EVGA 650 Ti 1gb | Windows 10 VM

Abusinq · August 20, 2021

I just got a new server for mass storage, and small games. The components are listed below:

CPUs: 2x Xeon E5-2670 v2 (10 cores 20 threads * 2)

GPU: EVGA 650 Ti 1gb

RAM: 32gb 1600mhz ecc registered ddr3
Motherboard: Supermicro X9DRI-F

I have tried turning off Hyper-V.

I have tried following other guides for this problem.

I have tried updating the drivers using GeForce Experience.

I have tried adding multifunction='on' to the XML config

Here is my current XML config:

Any ideas to fix this would be greatly appriciated.

If I left out any information that is needed to help fix this, just ask.

Thanks in advance.

Try adding the GPUs ROM to fix the Code 43. 🙂

Just tried it with two different ROMs from techpowerup:

https://www.techpowerup.com/vgabios/131663/evga-gtx650ti-1024-120920
no luck

Did you also edit the ROM file downloaded?

See 6.7.

Yes I did. Sorry about the late response.

Probably need my own post, but also in the same boat here.

Went through spaceinvaderones YTs tutorials. Tried TPU edited ROM. CPUZ ROM and Spaceinvaderone vROM script. Tried a GT 610 and GT 710 card (Using their own ROMs of course). Both have code 43. Also tried al the Hyperv on/off, Seabios, OVMF, different machine type. Got a HDMI dummy plug coming just in case as well.

I may be a special case as I'm using a DELL R510 and a homemade eGPU (x4 to x16 adapter as the Riser only has 3 spare x8 slots). Unraid and VM can see the cards so don't think that would be a major issue.

EDIT: Dummy plug a no go, still Code 43. Will start my own thread
