It looks like the cpu scales up. I started playing a 1080p movie in XBMC, and it went up to 2666mhz on one cpu core, but it doesnt look like its sticking to that clock ratio. I tried again, still playing the movie, and its back down at 2ghz (then it goes up again, and then back again, etc.).
(so far it has dropped 23 frames, but it looks like it plays this HD movie okay. CPU1 is 60-70% and CPU2 is 60-70%)

I will try to look into it and try to lock them at 3Ghz. Any tips on how I do that, will be appreciated.
EDIT:
Okay, I turned off cpu frequency manager, and now its up to 2666Ghz on both, but shouldnt it be up at 3Ghz? Could it be something in the bios? Afaik I havent edited any cpu settings.
EDIT2:
I just installed cpufrequtils:
Code:
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 2.00 GHz - 2.67 GHz
available frequency steps: 2.67 GHz, 2.00 GHz
available cpufreq governors: userspace, conservative, ondemand, powersave, performance
current policy: frequency should be within 2.00 GHz and 2.67 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.00 GHz.

It says the hw is limited to 2,67GHz, why? My cpu is suppose to be 3ghz. Anyhow, Im guessing its an BIOS issue, so I have to get in there to check. Im going to check that tomorrow (got to use my roomies usb-keyboard, all I got is bluetooth keyboard).
Thanks for all your answers. Will post back the results.
