It's not supposed to work unless you've got a mobile or mobile modded Palomino, Tbred or Barton (and half the bartons and later Tbreds can no longer be mobile modded) most of the KTs work when all the ducks are lined up... however... there's a motherboard behaviour thing that can shoot you down with modded CPUs, in that it will try to boot at max mobile multi, which is 24 on the early moddable chips, which anything but a unicorn golden sample won't boot. So you either need an additional mod to tie it down to a mobile multi it will boot, or to rig some other workaround.
No, you're mixing two things here, multiplier unlocking and software multiplier changes passed through the chipset.
A desktop unlocked chip will never work with setmul's multiplier changes, and it probably won't even allow you to try because it detects the kind of chip you have installed beforehand.
What I was trying to convey was that the chip I tried this with (thoroughbred btw) was not an XP-M but a "Mobile Athlon"... And I don't even know that there's any difference between them. If we look at their spec, we see the following:
Mobile Athlon XP 1500+ 1300 MHz 256 KB 200 MT/s 13x 1.45 V 35 W AXMD1500FQQ3B
Athlon XP-M 1500+ 1300 MHz 256 KB 200 MT/s 13x 1.5 V 35 W AXMD1500DLQ3B
From what I can tell, mine is slightly better at 0.05 volts less than the XP-M, but these are exactly the same chips, supporting the same feature sets... I just used this because it was the only other mobile chip I had other than the one installed in my KT7A which I did not feel like removing.
