Thinkpads Forum

Hey,

I am planning to undervolt my T8100 on my T61 because it tends to get hot, especially when used on a lap or other non-hard-non-flat surface for an extended period of time. I am planning to use FlipFire's Undervolt Guide to do so. (See http://forum.notebookreview.com/hardwar ... guide.html for details)

However, I also use the Thinkvantage Technologies Power Manager 3.25 and am concerned that using RMClock will interfere with and cause problems with the Power Manager settings and driver. Does anyone have any experience with using RMClock to undervolt alongside the Power Manager profiles. I am happy with the benefits and effects of the Power Manager on Battery performance, but I just need to lower these temperatures.

Primary reason is that I think my fan is on its way out. It has started to make an audible whirring noise on the rare occasions, but as fans go, I am sure that unless temps are controlled, further stress will likely make the noise worse and more oft-occurring.

I make use of only one power profile, a custom one, that uses the following key power management settings:
Battery:
- Maximum CPU Speed = Lowest
- CPU Deeper Sleep = Enabled
- Optimize Fan Control = Balance all Parameters
- Hybrid Sleep = Off
- System Cooling Policy (Processor Power Management) = Passive
AC Power:
- Maximum CPU Speed = Highest
- CPU Deeper Sleep = Disabled
- Optimize Fan Control = Maximize Performance
- Hybrid Sleep = Off
- System Cooling Policy (Processor Power Management) = Active

Any help, tips of experience, or other criticism or comments are greatly appreciated.

Thanks in advance,
Sincerely,
Faken Jones.

Hi,

I'm using RMClock in my T61p and there is visible result: the temperatures are 3-8 degrees lower. To avoid any interference with Power Managaer you have to disable power management (In RMClock) based on OS. My current settings in RMClock are "power on demand" and they work OK.
