George B. <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #78 from George B. <[email protected]> 2012-08-29 10:49:00 --- Hello, I think I also have this problem on my Dell Precision M4600 laptop. --- processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz stepping : 7 microcode : 0x23 cpu MHz : 800.000 --- (There are 8 cores in total, all limited to 800MHz). cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_min_freq --- 800000 800000 800000 800000 800000 800000 800000 800000 --- cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq --- 2301000 2301000 2301000 2301000 2301000 2301000 2301000 2301000 --- cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq --- 800000 800000 800000 800000 800000 800000 800000 800000 --- cpuinfo_cur_freq remains the same even when I put 100% load on the cores. In my case I do not appear to have the thermal throttling mentioned in comment #61: grep . /sys/class/thermal/*/* 2>/dev/null /sys/class/thermal/cooling_device0/cur_state:0 /sys/class/thermal/cooling_device0/max_state:10 /sys/class/thermal/cooling_device0/type:Processor /sys/class/thermal/cooling_device1/cur_state:0 /sys/class/thermal/cooling_device1/max_state:10 /sys/class/thermal/cooling_device1/type:Processor /sys/class/thermal/cooling_device2/cur_state:0 /sys/class/thermal/cooling_device2/max_state:10 /sys/class/thermal/cooling_device2/type:Processor /sys/class/thermal/cooling_device3/cur_state:0 /sys/class/thermal/cooling_device3/max_state:10 /sys/class/thermal/cooling_device3/type:Processor /sys/class/thermal/cooling_device4/cur_state:0 /sys/class/thermal/cooling_device4/max_state:10 /sys/class/thermal/cooling_device4/type:Processor /sys/class/thermal/cooling_device5/cur_state:0 /sys/class/thermal/cooling_device5/max_state:10 /sys/class/thermal/cooling_device5/type:Processor /sys/class/thermal/cooling_device6/cur_state:0 /sys/class/thermal/cooling_device6/max_state:10 /sys/class/thermal/cooling_device6/type:Processor /sys/class/thermal/cooling_device7/cur_state:0 /sys/class/thermal/cooling_device7/max_state:10 /sys/class/thermal/cooling_device7/type:Processor /sys/class/thermal/cooling_device8/cur_state:0 /sys/class/thermal/cooling_device8/max_state:15 /sys/class/thermal/cooling_device8/type:LCD /sys/class/thermal/thermal_zone0/mode:enabled /sys/class/thermal/thermal_zone0/passive:0 /sys/class/thermal/thermal_zone0/temp:25000 /sys/class/thermal/thermal_zone0/trip_point_0_temp:107000 /sys/class/thermal/thermal_zone0/trip_point_0_type:critical /sys/class/thermal/thermal_zone0/type:acpitz --- Kernel version is 3.2.0-3-amd64 (Debian Sid).
