Hi,

I have a K5000M mobile GPU and have installed the recommended 310.32 driver.

CUDA and OpenCL both report 601MHz clock rate and 1500MHz ram clock. Shouldn’t this be 700+ and 3000?

I have set to max performance settings in nvidia-settings, which it claims as 324MHz graphics clock and 1500mhz memory clock.

Any help would be appreciated.

Seems like it is the same issue as I reported. [url][https://devtalk.nvidia.com/default/topic/527882/clock-speeds-linux-gtx-660/[/url]](https://devtalk.nvidia.com/default/topic/527882/clock-speeds-linux-gtx-660/%5B/url%5D).

Could you check if it is the same for Windows and if you have the same performance issue (renders a 3D image 1.5 times slower on Linux) as I have?

Best regards  
Martin
