speedfreq speed specs

root@yoda cpufreq # speedfreq -c
CPU speed: min 2650MHz, max 10600MHZ, current 2650MHz; 25.00% idle
CPUfreq driver: p4-clockmod

So while I'd like my box to be this fast, its just an old 1.3GHz P4. Where does speed freq get these numbers ? Can I fix them to be more appropriate to my box ? Will these numbers effect my power saving, fans, etc ?

um or are my metric conversions off? damn metric system

Hz is cycles per second, so there's no metric/imperial conversion problems.

erm... Hyperthreading didn't come about until ~3.0GHz so it's prolly not that...

P4 throttles Hz only when it gets too hot AFAIK, so it should behave normally so long as your HSF doesn't fall off. But I'm guessing you wouldn't be using speedfreq unless you're a laptop.. geh.

Other than that I don't know jack about speedfreq...

Although, I'd speculate that these numbers are actually configuration settings... cpufreq might not actually "do its stuff" unless the actualy clock frequency is in range. Current is gax cos it _is_ out of range. Otherwise "current" is probably chosen based on heat or whatever policy speedfreq is imposing.

Or something.

Moo.

???
and this is when compling when speedfreq -c reports:
speedfreq -c
CPU speed: min 2650MHz, max 10600MHZ, current 10600MHz; 0.00% idle
CPUfreq driver: p4-clockmod

huh ? how fast ins this thing really running ?
