Stuck at FULL memory utilization

[TheGermanEngie]

Hi all - 

 

My saga of the modded Tesla M40 continues. The first problem I've continuously had was when checking GPU-Z, it shows all 24GB of VRAM being used up, even at idle. Running workloads didn't seem to matter, and it processes workloads just fine without any OOM errors. But GPU-Z, HWiNFO, and MSI Afterburner both say the memory is fully used.  Tried driver reinstalls, windows updates, can't seem to get anything to work.

 

Maybe it has to do with be using a non UEFI GPU (radeon 5450) for display? Or that it's installed in W10 Pro? The Tesla is in the first X16 slot and has full PCI-e bandwidth.

 

Also, when checking the Task Manager, neither the Tesla shows up nor the Radeon 5450 being used to power the display.

 

Tesla Drivers: 452.39 for Windows 10 Pro, CUDA 11.0, 9/22/2020, top X16 PCIE 3.0 slot

Radeon Drivers: 15.201.1151.1108, 11/4/2015, bottom X16 PCIE 2.0 slot

Windows 10 in UEFI mode, GPT disk, CSM disabled.
