The multiplier

I have the AMD Athlon 2100XP. I have attempted to unlock it....Ive changed the multiplier on the motherboard itself (to my knowledge there isn't a bios multiplier¿ unless there is hidden options like CTRL+F4 or whateva it is). I set it from Auto to 11X. But it still boots @ 13X .. I wanna get this beast @ 11X166 in sync with my ram if poss totalling 333 FSB ... If it still boots @ default does this mean its not properly unlocked? ... gazz

First is it a Palomino or a T/Bred and secondly how did you unlock it?
The 2100's are different from 1500to2000 to unlock.
If its a Palomino you have to join all the L1 bridges and also the 5th L3.
If its a T/Bred you only have to join the 5thL3.
The L3 joining is to enable the CPU to use the lower multis(12.5x and down)

ah ha ill try join ing the 5th L3 then get back to ya cheerz dude (its palomino)

How can I tell if it is a PAL or T/Bred? I have a 1800+ AMD XP.

The Palominos have a square core and it will have writing on it similar to
AX1800DMT3C
AGOIA ............
4...........
The T/breds have a rectangular core and the writing is on a black label below it, it will start
AXDA1800
and also will have similar to AIUHB OR AIUHA the last letter in either of these is whether its a T/Bred A or B.
Also the Palominos have the diodes underneath and the T/Breds have them on top.
