AMD MP 2000+ - change multiplier?

Hi,

I have a pair of AMD MP 2000+ processors that were purchased in 2001. I am not sure what core it is (I suspect its Palomino). I would like to change the multiplier from 12.5x to 16.5x using the diagrams from this site :
palomino: http://www.ocinside.de/go_e.html?/html/workshop/pinmod/amd_pinmod.html
thoroughtbred: http://www.ocinside.de/go_e.html?/html/workshop/socketa/tbred_painting.html

(note '-' is cut; '|' is joined)
If core is palomino then,
L1 is ||-- and L10 is |- (12.5x, 1663 MHz)
of
L1 is |--| and L10 is -| (16.5x, 1663 MHz)

If core is thoroughbred then,
L3 for 12.5x (1663MHz) is:
--|||

L3 for 16.5x (2195MHz) is:
--|--

Will I be able to make this big a change in multiplier? Will it work?

You should be able to completely unlock a palomino by connecting bridges on the top of the chip. That way you can change the multi in bios.

However, it requires a conductive pen. Im sure there are still how tos floating around on the forums from a while back.
