"Undervolting" Technique for Cooler Laptops!

DarkDavil · 23 Nov 2009

Many options are available for laptop cooling, and as i have an HP, i don't know why, they tend to be "hot" laptops, all 5 of my HP laptops have been very warm. Recently, i've found a GREAT solution to this problem!! My Specs are all filled out, and you may ask me any questions here if needed :) First, look at this picture i took a couple of minutes ago :P

I have a 100% CPU Load, using very few ram, and my laptop fan i NOT on, and I'm at 41-43 Degrees Celsius... thats great, where usually my fan would be going nuts. As i am much tooooo lazy to write a tutorial to do this, please check out this link, its on a "under-volting" guide i followed closely, and now my laptop is great. Please remember to STRESS TEST!!!! or you will BSOD a lot...

Good luck to all those with laptops!
The "Undervolting" Guide

Please reed that posters entire post, and carefully :)

Applies to all types of Graphics Cards, and Intel/AMD CPU's, HDD and SSD's .

I wonder if that'd work on my Atom N270 netbook...

Interesting.... though you could try it out

But, all you'll get is BSOD's if it won't work

So back up data ^^ I got like 3 BSOD's when i put my voltage's too low :) But now I'm all perfect

, and currently running a stress test that I'll continue to run all night :)

If you undervolt an Atom, what will you be able to use it for? Atoms run @ ~1.6G right? Undervolting it will probably force you to take it down to 1.2-1.4, probably gonna be too slow.

Well, thats the nice thing of undervolting.

You do not reduce clockspeed or other performace factors.

To Ensure stability the system will always give the cpu a little higher voltage than it needs. Thsi level is defined and fixed from INTEL/AMD. However depending on the chip you got in your box it probably needs a little less. In other words there is a margin between requierd voltage and given voltage. With undervolting you reduce this margin and therefore you save some power

I want to try this but RMclock says "Unknown Model" for my cpu . I have an AMD Athlon X2 QL-62. Under Profiles I only have "No management" . Any sugestions ?

Thanks DarkDevil! I just reduced my laptop operating temperature by 15 degrees C.

I was actually joking, since the CPU is only rated at 2.5 watts...

There ya go. WhatYouSayIsn'tWhatIGet.

Nop. Undervolting has NO decrease on performance/clock speeds. Undervolting isn't UnderCLOCKING. Undervolting simply sends the appropriate amount of power to your INTEL/AMD chip. Because, straight out of the factory, your chips are being sent the default amount of power, which usually means too much. Undervolting only makes the power at the level your Intel/Amd chip should be receiving it. GL all :)
