Thanks, I'll try. Looks like nvidia-settings can only read the clocks, not set them? nvidia-settings -q GPUPerfModes -t; nvidia-settings -q GPUCurrentPerfLevel -t; nvidia-settings -q GPUCurrentClockFreqs -t displays their current value. Setting them appears to require changing kernel module parameters (either in xorg.conf or /etc/modprobe.d/mumble).
