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.
Interesting. Are 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.
Weird stuff.
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.
Yes, they 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!
