    As a note, though, since I notice you dual-boot Ubuntu, the undervolt values used by RW-Everything obviously won't carry over to your Ubuntu install. That said, there is a way to apply the lower voltages in Ubuntu as well--I believe it is covered in the SPCR thread I mentioned in my first post (there's someone using Ubuntu on his dm1z in that thread).
    Funny you brought that up, yes I went through that thread yesterday and (through a couple hours of figuring things out) have my undervolts in Linux too, where the fans turn off even more often I would hate for anyone to have to do all the digging I did to figure out undervolting the E-350 in Linux, so I've written a draft of a newb friendly guide to undervolting in Linux, applying those undervolts at startup, and applying them on resume from sleep or hibernate. which I can post here if people want

    Only one Q: in a new thread or in here?

    Sounds great, glad that worked out for you! You can create a new thread in this subforum, perhaps "Undervolting the Thinkpad X120e in Linux," and I can link to it in my original posts.

    Just wanted to register and say thanks for this guide, very helpful.

    Also figured I'd go ahead and throw my results into the mix as well since I found other users results very helpful when undervolting.

    P0: 1600MHz @ 1.175V
    P1: 1280MHz @ 1.050V
    P2: 800MHz @ 0.825V

    Also, does this technique undervolt the GPU portion of the E-350, or does it only affect the CPU portion? If the latter, would it also be possible to undervolt the GPU in this way?

    edit: Found a GUI utility that appears to support both CPU and GPU/NB undervolting, it's called BrazosTweaker. Haven't really messed around with it yet, but looks promising.

    Would BrazosTweaker be a better tool than what was used originally for Overclock/Undervolt? It seems like a better user interface than rweverything, but is it more powerful?

    Looks like it has undervolt options for the northbridge, which I assume is the GPU side of things. That could be handy, and people had some trouble getting those settings to 'stick' with rw-everything.

    Have you tried it out yet? If anything the interface is MUCH nicer than manually writing to a bunch of registers.

    Undervolting the northbridge works at least for the s205, but not with the x120e. That's what i from reading the threads in german forums where the author supports his tool.

    Tested out that tool and saw the same behavior - can't get NB values to stick.

    I just wanted to ask about the NB part of Brazostweaker myself... Since I own a Wind U270 and not a x120e, I'll try this out and post the results here.

    Btw, here are my CPU undervolt settings :
    P0 : 1.125
    P1 : 0.975
    P2 : 0.7875

    I just have to found a way to apply this on my linux partition now^^.

    Also, too bad there's no way yet to overclock this netbook, I'm sure I could get very good results with it ...

    Most overclocking results on the E-350 platform are pretty mediocre. I don't think you're missing out on much.
