[Bug 1164557] Re: 1002:7145 [Lenovo ThinkPad R60] Laptop to hot - VID to high
Rainer, thank you for your comments. I can advise that unfortunately
putting in some VID logic in augmenting the ondemand governor, or the
cpufreq module in anyway like this is just simply not going to happen.
Despite this, one vital piece of information to know is are you able to
utilize the proprietary drivers for your card following
https://help.ubuntu.com/community/BinaryDriverHowto/ATI (strongly prefer
downstream, but upstream for testing would be fine as a worst case)?
** Changed in: linux (Ubuntu)
Importance: Medium => Low
** Changed in: linux (Ubuntu)
Status: Confirmed => Incomplete
** Summary changed:
- 1002:7145 [Lenovo ThinkPad R60] Laptop to hot - VID to high
+ 1002:7145 [Lenovo ThinkPad R60] Laptop too hot with radeon drivers
** 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.
WORKAROUND: Use the powersave CPU governor.
