Mobile 64 anyone?

I can confirm the experience of the fellah with no multiplier control. They
DO seem to 'default' to 1,000 MHz on a desktop motherboard for some reason.

I've been considering how to make one work on my KT400 motherboard with no
controls on it.

I thought I could try the wires in the socket trick.

He was saying something about having to cut a bridge to go to lower than
standard voltage, but I guess the standard voltage would be low enough.

I would think that would work but I haven't tried it.

I copied this message from alt.comp.hardware.overclocking.amd
Near the end it mentions the mobile 64.

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 ?

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.
