First I think it was a fan problem. I adjusted thinkfan to use the disengaged option. Now my fan is at maximum speed if the temperature goes over 67°C. But still it is not possible to run the laptop for a longer time an 100% CPU. It then overheats and stops working. For example just after clamscan starts working the fan is at maximum speed (5600 revolutions) and the temperature goes up over 85°C, the CPU usage is the about 70%. My standard governer is "ondemand". By using "powersave" the temperature will be about 5-10°C decrease. My investigation show me that in my opinion the VID is to high. To verify this I do the following: - rdmsr -p0 [1] 0x0199 for every speed steps - the governer "ondemand" switches the MSR 0x199 between - 0x0613, which means 1GHz and 1.275V? - 0x081c, which means 1,33GHz and 1.3875V? - 0x0b28, which means 1,83GHz and 1.5375V? > by 100% CPU the laptop overheats and stops - set the governer to userspace 1.833GHz - reduce the VID using: wrmsr -p0 [1] 0x0199 0x0b20 > the temperature goes not over 65°C by starting load that goes to 100% CPU!. I see that the VID is always set to 0x0b28 when the governor change the speed to the highest speed. I don't know if the governor or an other kernel module set the VID The Sped (FID) is selected by the governor. The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and every thing would fine. sudo lshw -C display; uname -a; lsb_release -a *-display description: VGA compatible controller product: Radeon Mobility X1400 vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:16 memory:d8000000-dfffffff ioport:2000(size=256) memory:ee000000-ee00ffff memory:ee020000-ee03ffff Linux BN591-LINUX 3.2.0-40-generic-pae #64-Ubuntu SMP Mon Mar 25 21:44:41 UTC 2013 i686 i686 i386 GNU/Linux No LSB modules are available.
