Acer 5553g / Mobile Phenom N930 C-States

[Mathias Picker]

Hi,

my N930 reports C1 as lowest cpu state:

mp% sysctl -a|grep cx_supp
dev.cpu.0.cx_supported: C1/0
dev.cpu.1.cx_supported: C1/0
dev.cpu.2.cx_supported: C1/0
dev.cpu.3.cx_supported: C1/0

I searched the net, but I can't tell if that's correct. 

The system runs rather loud with FreeBSD (fan running full speed, cpu
temp around 59°C).

I can't switch off the second graphics card, one of my last ideas of
getting it any cooler would be c2/c3. I've followed every other tip from
TuningPowerConsumption and need still around 3315 mA.

Thanks for any help,


Mathias
