A7N8X does not change multiplier on mobile CPU

Yes (or just an unlocked CPU). You should still be able to change the
multiplier of your psuedo-mobile in Windows/Linux though.

If you could adjust the multipliers in the BIOS in another board, that
indicates that the chip is unlocked, and the problem is with the board not
setting the multipliers right (as opposed to the chip being locked).
Possibly the board does not correctly support mobiles, so the BIOS
multiplier is being overridden by the PowerNow one.

This is not supported for nforce boards, so no luck here :-(

I changed them cutting the L6 bridges, but they are beeing ignored with the
A7N8X. I´m starting to suspect that changing multipliers in Bios only works
with real mobiles

What your K7S5A (non-NF) board was doing was setting the maximum (as
specified by the L6) PowerNow multiplier on boot, since the chipset
supported PowerNow. The startup (L3) multiplier is not changable on locked
chips, and since the NF chipsets don't support PowerNow (as you know   ),
the chip is stuck at the startup multiplier. Changing it into a mobile chip
does not unlock the startup multiplier: it only allowes changes to be made
through PowerNow. I've got a bit of a rant/discussion on how to think of the
multipliers at
http://www.emboss.co.nz/amdunlock
that may be of some use.

Wow! Super FAQ! It´s the first really Up2date FAQ I see. Till now I just
could find mixed up information on old and new superlocked CPUs.
So I´m not lucky, thanks for your help.

I don´t believe PowerNow will be ever supported on nforce boards, but they
are IMO still the best SocketA Platform

Tbred?
Barton? Whats your core?
Mine is a Tbred Core, running 2,175 (2.17 GHz) And is an Athlon 2200+
1.8GHz chip.
Same board.
multiplier is @ 14 x 155.4 @ least thats what CPU-Z Gives me


Denny. :-)
