TCC mode with GRID K520


I use a server with a GRID K520 graphic card. I’m running Windows Server 2012


and I installed the lastest driver version (320.59).

As I can see my K520 card with nvidia-smi.exe in the list, I’m not able to set driver mode to TCC and so I’m not able to run my applications using OpenCL and CUDA.

Could you help me?

Many thanks.

Can you try nvidia-smi.exe -fdm 0/1 to enable/disable TCC?

Hi, thanks for your answer.

I already try it and unfortunatelly it doesn’t work. I got a message like “Unable to set the driver model to GPU 0:00:03” or something like that.

I got the answer from Nvidia. K520 doesn’t support TCC mode.
