Mobile Barton 2500 Unlocked ?

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

Are all Mobile Barton 2500 chips unlocked. I can get an "AMD Athlon XP
2500+ (Barton) 1.88GHz 266 FSB 45WMobile" chip
for about $95 but I do not want it if it is locked. Anyone know how to
tell ?

Thanks,
jmr

    ALL mobiles are unlocked so that they can use powernow's multi-changing to
    save laptop power.
    They always will be.

    This is a common misconception. The
    normal/BIOS/L3/whatever-you-want-to-call-it multipler can be locked without
    affecting PowerNow. In fact, I've commented in various places that I'm
    surprised that it's NOT locked, as the chips come off the same assembly
    line. The ability to change the multipliers through PowerNow is, of course,
    required for all mobile chips. So you will always be able to change the
    multiplier through this on mobile chips, though as soon as (or if) AMD locks
    the L5/L6 bridges as well, then you'll only be able to change it to below
    the default multiplier. This is the case, in the AMD64 mobiles, where there
    are no bridges.

    PS to the OP: the 45W mobiles are the good ones to get for overclocking, as
    opposed to the (cheaper) 70W DTR chips.
