Hi,
I've read every post on this thread. Amazing!
I finally applied the mod to a Palit GTX680 to produce a K2 and passing this through XenServer (credence Beta) to Win 8.1 enterprise. Unfortunately, once I install the drivers, the card comes up with a yellow icon in Device Manager, saying that the card is not working. If I disable, then re-enable the card, Device Manager seems to like it.
Unfortunately, I don't believe the card is working correctly. For example, the GPUZ attachment detects the GRID K2, but doesn't detect any of the other parameters correctly. No BIOS info, none of the Senors are working, and the Memory is the wrong size. The card I have is only a 2GB card. None of the Clock information is shown. And this card supports OpenCL, CUDA, and DirectCompute, but none of those items are selected.
Please see the attached file.
In the XenServer host, nvidia-smi give the following output:

A Grid K2 card is supposed to show CUDA process names in nvidia-smi. "nvidia-smi stats" also says that my card is unsupported.
I also have an unsupported GeForce 6200 in the same XenServer host as the primary display. Not sure if that is causing some Nvidia conflict?
Any thoughts on what could be done to get this GTX680 (now K2) card to work correctly under XenServer with Win 8.1? I would love to get the vGPU stuff to work, and XenCenter gives me lots of vGPU options, but when I start the VM with the vGPU, XenServer complains:
Internal error: xenopsd internal error: Device.Ioemmu_failed("vgpu exited unexpectedly")
Considering that the passthrough card is not detected correctly inside the VM, I suspect there is something fundamentally incorrect with either the mod or my XenServer setup? Any thought?
Thanks!
