NVIDIA GeForce 740 not supported #100

Can you supporte NVIDIA GeForce 740. T_T Thanks!!!!

Dardrai commented 2 years ago

no that is not possible - your card is from the Kepler Generation: https://docs.nvidia.com/grid/gpus-supported-by-vgpu.html and Kepler was removed from vGPU - it was supported on GRID4 and prior and then dropped for vGPU 5 and newer. So we do not have the functionality in the driver for that generation of cards and thus can not just unlock the card. So 2 options: try an very very old driver or update your GPU to a "supported one"

Also just to mention I found 2 Cards with GT740 a 1GB GDDR5 card and a 2 GB DDR3 - https://www.nvidia.com/en-gb/geforce/graphics-cards/geforce-gt-740/specifications/ both cards are fairly low on vram anyways - splitting that up would give you a 512MB slice and/or a 1GB slice (depending on which card you have), which is for most cases not enough. And if we talking about the community merged driver with vGPU_unlock it's "even worse" because your host would need some vram too - my Host uses roughly 2-3GB Vram (1080Ti) without any vGPU slice started (yes I use a merged driver)

It is possible, you must set up Xen and use an older driver series. I have run vGPU on a 1GB Kepler GTX 650. In your case you could spoof to GRID K1 after setting things up. Instructions for Xen setup can be found in my vGPU Kepler unlock repo (using patches from mcerveny). Warning: it is not easy and may take a few days or weeks based on your knowledge level.
