Hi Norman, If you are seeing multiple frequencies supported, then you are probably ok. There is an issue where on some systems background activity can cause the system to "too easily" run at the faster speed. You can workaround the issue by changing this line in power.conf:
cpupm enable to cpupm enable poll-mode Hope this helps, and sorry you are hitting this. -Eric Norman Dankert wrote: > I got a Pentium Dual Core E5200 on a Gigabyte EG43M-S2H and installed > os2009.06 on it. > > My problem is, that it is always running at the max speed (2.5 GHz) instead > of switching to one of the lower frequencies, which are listed under > supported_frequencies. > > Is my CPU not supported or is there something I can do? > > power.conf has these two lines: > cpupm enable > cpu-threshold 1s > > kstat cpu_info looks like this: > module: cpu_info instance: 0 > name: cpu_info0 class: misc > brand Pentium(r) Dual-Core CPU E5200 @ > 2.50GHz > chip_id 0 > clock_MHz 2500 > clog_id 0 > core_id 0 > cpu_type i386 > crtime 36,640381924 > current_clock_Hz 2500000000 > current_cstate 1 > family 6 > fpu_type i387 compatible > implementation x86 (chipid 0x0 GenuineIntel 1067A > family 6 model 23 step 10 clock 2500 MHz) > model 23 > ncore_per_chip 2 > ncpu_per_chip 2 > pkg_core_id 0 > snaptime 10476,139242704 > state on-line > state_begin 1245917920 > stepping 10 > supported_frequencies_Hz > 1200000000:1600000000:2000000000:2500000000 > supported_max_cstates 1 > vendor_id GenuineIntel > > module: cpu_info instance: 1 > name: cpu_info1 class: misc > brand Pentium(r) Dual-Core CPU E5200 @ > 2.50GHz > chip_id 0 > clock_MHz 2500 > clog_id 1 > core_id 1 > cpu_type i386 > crtime 40,798983561 > current_clock_Hz 2500000000 > current_cstate 0 > family 6 > fpu_type i387 compatible > implementation x86 (chipid 0x0 GenuineIntel 1067A > family 6 model 23 step 10 clock 2500 MHz) > model 23 > ncore_per_chip 2 > ncpu_per_chip 2 > pkg_core_id 1 > snaptime 10476,139826385 > state on-line > state_begin 1245917924 > stepping 10 > supported_frequencies_Hz > 1200000000:1600000000:2000000000:2500000000 > supported_max_cstates 1 > vendor_id GenuineIntel >
