[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.
