Mobile Barton XP on A7V400-MX?

Couple of newbie questions...
Does A7V400-MX provide the low Vcore for mobile XP?
What multiple will it set the CPU to?
Thanks in advance.

Get another mb... You can only set the multiplier and vcore within
windows via cpumsr. The bios as of now (maybe bios upgrades in the
future will support it) doesn't support vcore and multiplier adjustments.

To answer your question directly, this mb sets the multi to the set one
of a regular xp (non-mobile). ie, my xp 2000 converted to xp-m has
bridges set to 16x max multi, but it still boots up at 12.5x.

The vcore on the other hand will boot up at the cpu's setting. ie, if
your xp-m is 1.45v, then that's what it will boot with. It's an ok
board, but the lack of bios support for multi/vcore throws some people off.

Hope that helps.

That is not the question to ask. Rather, how will you set
the multiplier to something other than the low default
value ? If you set the DSW to 200MHz, the multiplier is
pretty low, like 5 or so.

To get the most from the mobile processor, you need a
motherboard with programmable multiplier. I use a
mobile 2600+ on an A7N8X-E and run it at 200x11. So,
perhaps an Nforce2 motherboard with programmable
multipliers would be a better platform for the experiment.
(Download the manual and check the BIOS options, to make
sure multiplier, FSB clock, and Vcore are programmable
in the BIOS.)

You can always do socket mods or bridge mods to set
the multiplier, but that is a painful way to do it.
The same is true of Vcore - it can be programmed via
mods as well:

The mobile and desktop processors define Vcore
differently. See "L11 : Code to CORE Voltage Definition"
on this page:

http://fab51.com/cpu/barton/athlon-e23.html

My processor is FQQ and the (Q) Vcore setting is
1.450 for a mobile socket, but when plugged into a
desktop socket, the Vcore will make 1.575v. The
extra voltage will help you overclock, but again,
an adjustable Vcore allows finer tuning of performance
versus heat. I currently run mine at 1.65V while
doing 200x11 (3200+).

HTH,
Paul

Hey, thats cool! I never heard of this one before. Should be
fun to play with...

Thank you for you (and Pual's) replies. To clarify... For people that
doesn't want to overclock, does it make sense to buy the mobile version
instead of the straight XP? I am looking into xp-m mainly for lower
power consumption (less colling and noise...) more then anything else.
If I do get one, does this mean it will take a long time to boot into
Windows until I use cpumsr to speed it up? Is there a way to run cpumsr
in a script so it can be done as part of the boot up?
Thank you again.

Well, one point I overlooked that paul had written is that if you put a
mobile cpu in a desktop mb, the voltage goes up, so really, the mobile
running cooler may be an insignificant factor. A 1.45v mobile boots as
1.55v I believe (I could be wrong). On your mb, the only way you could
change that voltage is by modding the bridges on the cpu, or wire
modding the socket to achieve a higher or lower voltage. Since you do
not wish to overclock, it would probably be in your wallet's best
interest to just get a desktop version as they run at 1.6 - 1.65v (again
I could be wrong, but my xp 2000 runs a stock 1.6, and it's pretty well
a bottom line cpu).

Then again, this is just a suggestion, as you may want a mobile for that
2C drop in temp, or maybe you want to overclock it in the future.

Hope that helps bud.
