Mobile Barton vs. regular Barton: any advantages?

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

No, there are no performance advantages when running at the same speed. The
main advantage the mobile has is that it's unlocked. I've found that the
latest desktop cpu's (week 10 / 2004) overclock just as well as the mobile
and at the same voltage...but the desktop version is locked.

Question when will the mobile versions be locked? Can AMD lock them
also, and if so have any been reported locked yet?

I'm trying to get one at the end of the month but that may be too late
;-(.

Thanks

They probably won't ever be locked. The fact that they're unlocked is
what lets the notebooks slow the speed of the processer when less
performance is needed.

Is that correct? I can believe the "top end" might be the same. But what
about at lower voltages?

I have only had 2 mobile 2500's, so I am not an expert, but both of them
were a little disappointing in terms of top-end performance (both would only
go to around 2450MHz Prime95 stable). But on the other hand, they do seem
to need less volts than other Bartons I have tried. For example I am
running my current CPU at 2400MHz at 1.65v. I wouldn't have thought you
could do that with most desktop Bartons. My 3200+ needed 1.75v to do
2310MHz and 1.85v to manage 2400MHz.

The highest possible multiplier is locked AFAIR. So you just can
underclock. Opening the L6 bridges allows Ocerclocking, but fiddling wiht
the CPU means you just can go for a non mobile and mod it.

I don't understand what you are trying to say.

My mobile is unlocked and my motherboard allows me to set any multiplier I
like. 5x, 22x... whatever.

Desktop and Mobile Bartons are basically the same chips... the difference is
that the Mobiles are tested at lower voltage...there is nothing to say that
the desktops definitely won't work at the same low voltage.
I found that a week 10 / 2004 desktop needed about the same volts for any
given speed as my week 52 / 2003 Mobile.....Maybe the CPU I got was
exceptional?

Sort of correct   The L3 bridges can easily be locked (ie: no multiplier
changing with NF1 or NF2 boards) without affecting the PowerNow
functionality. I've made several posts on this in the past, my favourite
being:

That means you L6 bridges are all open

I suspect it might have been. Most of the desktop Barton 2500's I have seen
needed a little over 1.65v (perhaps 1.675 or 1.7) just to run 3200+ speed.

Of course as the steppings get better perhaps they are all better than this
now.

I have no idea whether they are or not. All I know is that I have a normal,
retail Athlon XP Mobile 2500. All XP mobiles are completely unlocked like
this.
