Hello,
about my environment:
- Palit GeForce RTX 4080 GamingPro OC
- Ubuntu 24.10
- nvidia-driver-560 (non-open) installed from Ubuntu repos via ‘ubuntu-drivers’ cmd tool
- GSP disabled via kernel parameter ‘nvidia.NVreg_EnableGpuFirmware=0’
The output of nvidia-smi is as follows.
# nvidia-smi -q -d CLOCK

The Max Clock of Graphics (shader) & SM (Streaming Multiprocessor) is reported to be 3150 MHz.
As per https://www.nvidia.com/en-us/geforce/graphics-cards/40-series/rtx-4080-family/ the RTX 4080 has a boost clock of 2.51GHz, which is what I’d expect as Max Clock value for Graphics and SM.
Windows 10 3rd party tools report sane values for base and boost clocks. Is this an issue with nvidia-smi or am I missing something?
