How to Unleash CUDA performance of Titan V on Windows 10

Titan V GPU clock is capped at 1335MHz when it is used as CUDA compute device.

 Fig.1 GPU Clock is capped at 1335MHz

 

In order to lift this performance cap and draw full CUDA performance from Titan V, it is necessary to run the following nvidia-smi command with administrators privilege:

"C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe" --cuda-clocks=OVERRIDE


Fig.2 GPU Clock is increased to 1575MHz
