It's very good idea to reduce voltage of CPU via RMClock Utility 2.25 On my C2D i've reduced voltage from 1,2 V to 1,0 V (Computer is still stable and all WU are valid). On my second one, mobile AMD 64, i've reduced from 1,35 to 1,2. Temperatures have droped even 10deg. And additional to this less power is consumed (tests will be done later).

I have almost the exact same comment. Shaved a bit more than 0.2v (0.325 or something) off my voltage, for around 10C reduction in temps. Also, because the chassis didn't heat up so much the HDD temp dropped 5C also, and the fan cycles on/off much less frequently, and doesn't spin as fast.

RMClock is the greatest! Of course though, you have to check for stability etc too, but it's a day or two when you first set it up for long-term benefit.

Even crazier... growing up in

Even crazier... growing up in Canada we learned both English and French, and being in French Immersion I took Math class in French. So I was being taught to use a comma instead of a decimal point, but in any practical (real life) situation I would have to use a decimal point instead of a comma. Talk about confusing!

There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers. - Richard Feynman

As a previous respondent said.....

ALL LABTOP USERS SHOULD BE USING THE RMCLOCK UTILITY.

As he said, I have a dell 9300 running everything possible
including prime95 for years....no problems, no cleaning, and
runs 10 degrees cooler than without the utility.

If it will work on a dell labtop, it should work on any labtop.

Cheers.


I think you mean "ALL WINDOWS LAPTOP USERS" or maybe "ALL X86 LAPTOP USERS". To my knowledge RMCLOCK does not run on OS X or PPC.

Regrettably. Perhaps someone will code one, since it's even less likely that an Apple laptop bios would permit undervolting.

I too can not say more but recommend using RMClock (or NHC, if one likes) - after few years of use, I can not anymore imagine running Boinc on notebooks (but not only) without the ability to undervolt the CPU! (Except that the OS makers would icorporate something similar :-) (I thing similar tools are also available for Linux since the Pentium-M age.)

Does anyone know a good

Does anyone know a good monitoring tool (CPU temp, HD temp, CPU load and stuff) for Linux? I really enjoy running Linux but I kinda miss NHC. The KDE applet never worked quite right for me, apart from having limited functionality.
Running Kubuntu 7.10 on a Core Duo CPU.
I'd really appreciate some good advice.
Thanks in advance

Linux temp/fan monitoring for

Linux temp/fan monitoring for debian based distros:
sudo apt-get install lm-sensors

Then run sudo sensors-detect - and thats where things went wrong on my debian desktop, D975xbx2 mainboard, after a while of detecting sensors it shut down and didnt POST untill i removed the power cord for 10-20 sec. Doesnt work well on all mainboards then.

For Core/Core2 CPUs a much simpler utility is found here:
http://sourceforge.net/projects/icspll/
Unpack, cd to the icspll-1.1/cpucoretemp directory, now type ./run
CPU temps can then be read with cat /proc/cpucoretemp

edit, didnt mean to say lm-sensors is for debian only, check out http://www.lm-sensors.org/ for other GNU/linux flavors.

Thanks for the advice, just installed lm_sensors and it seems to work okay (temperature is realistic, at least) for CPU temp. Not as flashy as NHC, but it does what it's supposed to do ;-)
Is it normal that the temperature between the two cores is about 5° different?

You might check out Conky. I was using the system monitor that came with Ubuntu, but it was stealing 15% cpu cycles and that was unacceptable. Conky claims it's only using 0.20% cpu when I run it.

I'm not a Linux geek so I haven't been able to configure it beyond the basics, but it's doing what I want (cpu temps and top cpu users). It's supposed to allow you to trigger scripts based on certain events, but I don't have enough experience to get into that.
