Blender can't find GPU on Quadro 4000 and Quadro 2000M I've spent several days trying to figure out why Blender can't find my GPU in both of my workstations. On one, I have Quadro 4000. On the other, is Quadro 2000M.

One year ago I was able to install a special CUDA build from Graphic all and that version found my GPU for some reason. That version is now deleted from my PC, but none of the official builds of Blender show my GPU which is totally weird because there is nothing wrong with my hardware.
It feels such a waste of time digging for secondary builds on Graphic all when I know my hardware deserves better and I simply cannot understand why Blender refuses to find my perfectly fine equipment. (HP Z Workstation 420) plus another Z workstation laptop, on none of them finds Blender my GPU but Blender works fine on my CPU.

I have the latest Nvidia Quadro drivers for my graphic cards plus CUDA toolkit installed and all of this is perfectly healthy and running outside of Blender. Blender simply cannot see my existing CUDA stuff, visible in Nvidia Control panel.

My GPUs are not visible in ANY build of Blender (2.79 Official Stable Newest, 2.8 Official) I've installed so far, as I mentioned only was visible/usable (the GPU) in that single rare GraphicAll one (build) which I can't even find anymore. Forgot what to search/Google for.

Any tips would be super amazing.
Thanks 

(Update: I was able to install 2.79b and it finds my GPU but it would still be nice to be able to use GPU on 2.8 which is still Mission Impossible for me) :/

The Quadro 4000 supports CUDA compute capability v2.0 as seen here
https://en.wikipedia.org/wiki/Nvidia_Quadro#Quadro

Blender 2.79 supports NVIDIA cards with CUDA compute capability v2.0-v6.1 as seen here
https://docs.blender.org/manual/en/2.79/render/cycles/gpu_rendering.html#cuda

Blender 2.8 supports NVIDIA cards with CUDA compute capability v3.0 onwards as seen here
https://docs.blender.org/manual/en/2.80/render/cycles/gpu_rendering.html#nvidia-cuda

I believe the latest CUDA toolkit to still include support for the Quadro 4000 is v8.0 GA2 which can be found here
