kt7a and xp-m 2600+

hello,

to make it short:
bought a xp-m 2600+, put it in the kt7a, had to do a wiretrick (grounded
AJ27) to get multipliers of 13 and above.
with fsb 133 only 17 booted (2266mhz @ 1.6v).

my question is now:
what shell i do to get 15 ... 16.5 with fsb 133 to boot?

will additional AN25 + ground do anything?

i know Wes know it.

thanks in advance.
