2nd GPU Passthrough (VMWare 6.7)

[phoenix3dfx225]

Hey all,

Running the following system (and have for the past 6 years with some upgrades along the way)

Asus x99-S
Xeon E5-2696 v4 (44T/22C)
128GB 3200mhz DDR4
EVGA GTX 980sc
2TB NVME
1TB (x4 256GB SSD Raid 0)
10TB 7200RPM HDD

Recently was able to purchase a EVGA 3080ti (at MSRP) during a onsite event at Scan (UK) had to pre book and queue for the whole morning - well worth it.

To get back to the point, I have passed the 3080ti through to my gaming VM as the 980 was previously and I have a “mining” vm running nicehash which just used up any spare resources. This was just previously spare CPU cores.

I tried passing the previously working 980 now to the mining VM but once the Nvidia drivers install I get a BSOD with VIDEO TDR FAILURE.

Any thoughts and ideas why it might not be working. The 3080ti is working fine still but unable to get the 2nd gpu to passthrough to a 2nd vm.

I believe you need a proper Quadro to passthrough for more than 1 VM? Recently, nvidia allows 1 passthrough for consumer cards. Now that you have 2, maybe thats the reason you are having problems?

Have you tweaked settings to avoid the old Error 43 “feature”?

Hey,

I had used the hypervisor.cpuid.v0 string.

QUICK UPDATE: Now fixed. I rebuilt the VM and its now working Just as well my PC lives in the garage and is cabled through into my seperate mancave as a 980 and a 3080ti running will be toasty. Bring on Winter!
