[Bug 1164557] Re: 1002:7145 [Lenovo ThinkPad R60] Laptop to hot - VID to high
** Summary changed:
- [Lenovo ThinkPad R60] Laptop to hot - VID to high
+ 1002:7145 [Lenovo ThinkPad R60] Laptop to hot - VID to high
** Description changed:
My laptop goes to very high temperature. 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.
