NVIDIA driver perform continuously in one of these levels each slice of time.Here are some commands will display you current performance level and current frequency parameters:
Code:
$ nvidia-settings -q GPUCurrentPerfLevel -t
2
$ nvidia-settings -q GPUCurrentClockFreqs -t
425,666
As per the output of the following commands "425,666" in the example stated - current GPU frequency is 425 MHz, but the card has no on-board memory so there must be "425,0" (memclock=0 for perf=2). It seems as a issue in NVIDIA driver or nvidia-settings tool.
