Yes c states and cc6 states are enabled, 1 or 2 cores can get up to
around 100mhz or so less than turbo 2 however I cannot get the whole
advertised 8 or even 4 (i get max around 2.5ghz as reported by "cpupower
monitor" ), my temp is 35C with full load cpu usage and my fans nearly
off (tower cooler) so I don't think that could be the issue.
these the results of the turbostat program? What does
powertop show in the idle stats?
Powertop, around 96-98% or so.
Turbostat doesn't show turbo frequencies for some reason under tsc_mhz,
and average cpu freq is lower than wcpupower monitor reports.
With a single 100% cpu thread I can get to 3ghz (still a little short),
however with every thread I add the clock speed goes slightly down.
Is there a way to view and force c-states? I tried using
turionpowercontrol but it didn't work, the cpu simply clocked up again
and it only has a max cstate and not a min cstate option.
I am curious is there a way to disable the second half of the 16 core
CPU optys in coreboot?
- Do mismatched cpus work at their native clock
speeds? What would
happen if I inserted for instance a 6220 in to the second cpu socket.
should work at the native clocks. Don't even try mixing
different generations of Opteron even with the same socket, it won't
work, but a minor clock difference shouldn't be a problem in the same
overall family (e.g. mixing an 82xx with an 82yy should be OK).
I see, thanks!
