ESXI6.5 passthrough Nvidia K1

I built a virtual machine in ESXI 6.5, a Windows 7 system, and tried to use the Nvidia K1 graphics card, but it never worked.Look up all sorts of data on the net, still be not successful.

Win7 video card driver is installed, the system can also be recognized, but in the execution of dxdiag can not see the video card information, do not know where the problem is.

Can you remove the software VGA 3D from the list of that VM's devices? (Just let the pass-through device exist as the VGA device)  Then restart the VM and run the dxdiag and check the situation again

Have you installed the GRID-Drivers on the Hosts? The Drier-Version of this VIB MUST match the client driver version in the guest

As I saw earlier, pass-through does not require installing a vib driver,just install the driver in the virtual machine。

After removal, restart the virtual machine and it will be displayed

The Windows 7 machine can detect the K1 adapter, not sure why dxdiag doesn't.

Have you tried to connect to the VM using RDP?

Try to download the following demo from NVIDIA website and run it on the Windows machine:

Download A New Dawn Demo | Download Demos, Wallpapers, and Screensavers | NVIDIA Cool Stuff

If you aren't able to view the demo, or if it doesn't run smoothly, then please post a screenshot of the VM configuration (right-click on the VM >> Edit Settings)

Also go to Control Panel and open the nvidia Control Panel then click on System Information link in the bottom, and check the Graphics card information.

Dxdiag cannot be used with UDP connection

The driver I was using was provided by nvidia and I tried both versions 6.0 and 6.5

<<NVIDIA-VMware_ESXi_6.0_Host_Driver_346.42-1OEM.600.0.0.2159203-offline_bundle>>

<<NVIDIA-vGPU-kepler-vSphere-6.5-367.132-370.39>>

Below is a screenshot of the VM configuration

because you are using esxi 6.5 you need "NVIDIA-GRID-vSphere-6.5-367.132-370.39.zip" - accourding to this matrix: NVIDIA GRID™ Software Supported Products

Hi Kobebryant1,

You're trying to dedicate graphic adapter for a VM. This is called vDGA, where you configure a VM to use a the graphic adapter exclusively by adding a "PCI pass-through" device.

Please note that "Virtual Dedicated Graphics Acceleration (vDGA) does not work through the vSphere console session", as per page 16 of the following official guide:

https://vdc-download.vmware.com/vmwb-repository/dcr-public/9a81c15e-a7db-457e-ae4f-5b323a302661/be2a...

So you should use a "console" client that supports graphic acceleration. I believe RDP works fine, but didn't realize the dxdiag doesn't work through RDP. However, have you tried running a 3D application from RDP session?

I know for sure that VMware Horizon Client can give you a console session that supports 3D acceleration, but not sure what other option are available.

Also have a look at this KB:

https://kb.vmware.com/s/article/52631

Quote:

"Verify the VMWare Video Card setting for 3D Graphics indicates 3D Support is disabled."

And finally, please post the result of the Graphic Card information from the control panel applet as mentioned earlier.

Previously, I had been using RDP to connect to the virtual machine.

In win7 system I tried a lot, did not find a solution, today I tried win10, seems to be ok, screenshot below, next I use 3D program test,the results will be published here.
