Code 43, I thought nvidia stopped this

I am getting code 43 with my 1050ti. What is causing this? I thought nvidia stopped this for their devices. I am using proxmox btw.

AMD CPU, 1050ti.

This can be caused if there aren’t enough resources (addressing space) which shouldn’t be a problem with a 4GB 1050 ti what’s complete system specs

Resizer bar enabled?

no resizer bar enabled.

Try enabling it and toggle above 4g decoding see if on/off helps

will do. I thought it might be the bios. Enabled resizer bar and now windows just freezes on boot.

stays like that.

I will try creating a second vm to see if i can make it further.

You need to convert your disk to GPT for resize bar to work. - from memory

Still freezing after converting vm to gpt.

You are blacklisting everything correctly on proxmox yes?

And then you have to manually edit the vm’s conf file and add hidden=1.


vim /etc/pve/nodes/pve/qemu-server/401.conf

# add hidden field to cpu area
cpu: host,hidden=1,flags=+aes

And then add the PCI-E devices (for everyone these ID’s will be different)

I have not blacklisted radeon. I don’t have radeon gpus in the system. I will do that.

This is the tutorialk i followed.

So I think I solved it. That tutorial I linked does scisi for virtual disk. This time I chose sata and it works. I mean no freezing.

Nope froze again… After I installed the gpu drivers it froze.

I narrowed it down. It is when it is selected as pcie. Boots fine when it is basic pci.

Try giving it a VBIOs, or if it already is giving one, then give it nothing.

If I recall correctly, my Quadro M4000 give code 43 (which is a generic error that can be produced by many possible things) if it is given a vbios.

My RX 6700XT on the other hand requires one.

I am getting this output.

kvm: -device vfio-pci,host=0000:07:00.0,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0,rombar=0: Failed to mmap 0000:07:00.0 BAR 1. Performance may be slow

It works with amd gpu but not nvidia. go figure. Both 1050tis i have dont work, the amd gpu worked first try.

With the 6500xt i am getting

Failed to mmap 0000:09:00.0 BAR 0

so an update, i got gpu passthrough working on popos to windows. still no luck with proxmox.
