[SOLVED] 2060 super can't passthrough, please help~


Sep 26, 2019
Hi, I have a zotac 2060 super plus oc, and now I want to passthrough it to a win10 guest vm, but I can't install the driver successful.

The monitor that inserted to the gpu can display the win10 desktop, and when I install the nvidia driver, the vm would restart and become blue screen.

I have another nvidia 960, the same process (same everything, just instead the gpu and the vbios) and it can successful.

I run the 2060 super in the physical machine(the same machine), the driver is ok and run the 3d mark is normal.

I run the 2060 super in the Ubuntu guest vm, the linux driver is ok and I can use ffmpeg to deal some videos.

Here is my info:

4 X 8G ddr4 2400MHZ
256G Samsung 860 evo ssd
Ryzen7 1700
zotac 2060 super plus oc( insert the first PCIE slot, has vbios)

The win10 iso is download by Microsoft official web site.

The nvidia dirver is 436.30 desktop version.

I have two vbios for 2060s. First is exported by nvflash from physical machine(cut the head) , second is exported by "cat /sys/bus/pci/devices/0000:1c:00.0/rom" (the gpu is insert second slot, and passthrough to a win10 guest vm).
I think these vbios are useful, because I use rom-parse to verify and the monitor can display win10 desktop.

Please help me, I search these many days, and I really can't successful.
