Just do something that needs CPU power and powersaved will increase the speed automatically.
How would this relate to running something "nice" like a distributed-computing program such as Folding At Home? It's taking four days to process one of the larger work units on my 3200+ system. Is there a good way to speed it up without wasting too much power?
powersaved currently ignores "nice". It uses the load average, which is independent from it. So your Folding at Home client should always run at full speed.
I was relying on the output from /proc/cpuinfo, which now I note from the manpage of powersave is sometimes wrong, so I entered powersave -r and it
It shouldn't be on AMD systems. AFAIK the only case where it can be wrong is on a Intel system when your CPU is overheating and goes into thermal throttle. But that shouldn't happen anyways, unless your fan died.
gives me:
cygnia@cygniapolis:~> powersave -r 18426217103360.000000 MHz
It's probably the Hz value. I guess just the printed unit is wrong. The method powersaved uses to measure the performance is not 100% accurate and the hardware is also usually a bit off from the advertised value, so you don't get nice round numbers. -Andi
