    I am looking to undervolt my system (below in sig) but am not sure how.

    Any guides?

    Also -
    I have a T7700 - does anyone know stable undervolts for this CPU?

    Thanks!!!

    Great link +rep.

    Question still stands on the T7700 anyone know stable undervolts? Not looking for exacts, just a general idea of what I should shoot for.

    Also once you "set" these voltages, are then in the BIOS e.g. permanant, or do you have to re-do them if you reinstall your O.S. or w.e. or do you need to run a program constantly (lame)

    is there a way to make the changes permanant?

    Don't know whats good for a T7700.

    Voltages are set in the software only, once you exit they change back.

    You can use the undervolting Guide to test the voltages that are good for your cpu.

    You cannot set them permanently, the software goes in your tray and stays running.

    The voltages are set through the program in the guide, and the undervolt is only in effect when the program is running, all this is explained in the guide that was linked above.

    As for stable voltages, all processors are different so you will have to find your stable voltage by testing
    You have nothing to worry about as undervolting does no damage other that a BSOD, and reduced my temps by 10-15C :eek:

    The guide is very well written and details all steps with images

    Hope this helps :)

    Edit - Others beat me to it ;)

    Not really. I don't have a laptop (yet) but I can offer my experience from years of overclocking desktops. I even know what a jumper is!

    Every processor is different. This is a good thing because if they were all the same Intel would have undervolted it for you: nothing lost, nothing gained.

    Just start up whatever software you're using and take a small step down in voltage. Run orthos for a minute. No crashes, take another step and run othos for a minute. Repeat this until you get a crash. Then you step back up and run it until it crashes again, take a step up etc.

    Once orthos makes it overnight without a crash you are likely fine, but I would recommend running memtest86+ the following night and finally just taking a couple of passes through 3dmark06 until your system heat reaches equilibrium (and stays at it for a while). Basically be satisfied everything is in working order before beginning regular computing again.

    You can do that, but you will most likely run into errors and crashes.

    Audigy you should make a SetVOLT tool that does it automatically like your SetFSB :)
