I was actually joking, since the CPU is only rated at 2.5 watts...
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
My netbook runs soooo sweetly already I'd be loathed to fiddle further with it when it already has a number of tweaks applied to save battery life and underclock the atom if operating for extended periods without external power...

Yea, but undervolting DOES add 15-20 more minutes to your life But, honestly, its your choice, i enjoy my laptop running cooler and having more battery, if your happy with your current rig/build, then im happy for you too !

The only problem with RM Clock, which btw, I have been using for several years on my laptop to help keep it running cooler, is that the developers apparently have stopped working on it because there has been no new version in over a year and it is not compatible with many newer CPUs.

Also, there now is a 64 bit driver available for RM Clock somewhere (not from the developer of RM Clock) for it. Forget where I got it but I'm sure one can find it on Google.

There is another program that does the same thing as RM Clock but unfortunately, unlike RM Clock, is not free, called CPU Genie. But there is a free trial and CPU Genie has an automatic testing utility that will find the optimum voltage for each "step" of your CPU, so one can use the free trial of CPU Genie to do the hard work of figuring out the proper voltages to set your CPU at with RM Clock. Or, one can just stay with CPU Genie if you want an app that is still being updated and supports the latest CPU's.

Tried to use CPU genie but doesn't seem to work with AMD chips.

The heat issues in mine are due to a 320Gb 7200rpm WD HDD swap performed, which makes it run up to around fifty degrees to sixty degrees internally - and the nature of these tiny machines means airflow is poor.

It's under warranty so I don't much care, but another time I would certainly look more carefully at models with all aluminium cases that help dissipate heat.

The Nokia 3G netbook looks kinda kewl... but I haven't seen one in the flesh yet... and I'm sure there will be a plethora of new models next year, running W7 as opposed to good old XP...

That CPUgenie works quite well...

I have my processor now running at the rock bottom voltage for me (0.925V) up until the 10.0 multiplier (2000MHZ for me) with the max voltage ending up at 1.025

DarkDavil, could you please post anything here so I could rep you, to thank you for my cooler laptop.

The thread is too old to rep, need a new post.
