    Several months ago it was reported that AMD intended to multiplier-lock its future Athlon XP "Barton Core" processors. Well apparently AMD has gone ahead and done it, and now they're starting to show up in retail channels.

    Why is it that they all talkin' 'bout L1 bridges when T'bred's and Barton's rely on on the last L3 bridge? Have they changed the whole core without anyone else knowin'? :confused:

    OCW Guide: Unlocking mulitplier on Barton 2500+ Week 43
    Unlocking a week 39 or later AMD CPU

    The problem posed to us overclockers is that our dear 2500+ bartons were the first to become multi locked from factory. Tough they can, and still are, overclocked to 3200+ simply by changing FSB from 333 to 400, some bartons tend to be excellent overclockers and 2.4GHz+ are possible with these cpus, and not all of us have ram and boards that handle +200MHz. But AMD forgot (thankfully) to lock the L5 bridges which lets us change our cpu to a mobile XP or a Athlon with MP support.... and the story continues..

    Long story short:

    Amd made a program to adjust Mobile XP's multiplier and voltage on laptops to lower power consumption while the laptop is idle. By screwing with the L5 bridges on a regular Barton it can be made to be recognized as a Mobile XP by certain mobos. Then all you have to do is download the AMD program and you can adjust Multiplier through windows.
