Not sure were you would find those particular pins myself. I would stay with the basic closeing of the L1s.

you can unlock your t-breds with pins underneath but not the xp's AFAIK

This is a job for Candjac! The above thread was posted by him with a link to his Homepage. John knows CPUs insideout and backwards.

Same question at icrontic, same answer copied here.

Answer is yes and no, and explanation. re L1s.

Yes for the default 13X XP2100 cause most mobo/bios have issue/s with Multipliers greater than 12.5X. Tbred 2200 at 13.5X falls into this category as well, and the same pins apply to both, AJ27 and a nearby ground pin.
But the XP 2100 also needs to have all 5 of its L1s closed as well.

No pins mod neede for XP2000 and lower as there is no mobo/bios issue with these cpus..but of course the L1s need to be closed.

We prefer to call the pins mod and variants which reset the 8X bit Value LO, like the closing of Tbred 2200's rightmost L3 bridge, a "mobo/bios workaround" to distinguish it from the simple historical Duron/Tbird, XP2000 and lower, Multiplier "unlocking" by closing the L1s. It causes less confusion cause just doing the pins mod on an XP2100 will not let the mobo/bios reset the default Multiplier...you still have to close the L1 bridges. So a recent poster was totally confused until we made the above explanation about there being two separate issues in getting control of the XP2100's Multiplier.

And in the historical sense of the L1s, which are simple switches connecting mobo/bios circuits to CPU circuits as needed to reset/oc, ("closing" the L1s do not change any Multiplier signals like the pins mod does), the Tbred with its closed L1s comes unlocked...it just needs the workaround for the mobo/bios issue.

But simple as this seems to us, and others who are not aware of 2 separate issues...sure to get some flak for this posture.;-)

Edit:- Reread this thread and noted response by TheDude, got us to thinking maybe qwerty57 wants to control the Multiplier signals from the pins, like say with an ECSK7S5A mobo that has no Multiplier support. Then the answer is yes, for all XPs, Duron/Tbird, and Tbreds as well, and the link that TheDude posted is valid....but
user still has to close the L1s else there's no connection to the Multiplier signal busses.

yeeeeeeeees.....hmmm a bit confusing.....
so really there is no point on a XP using the pin mod..or changing your multiplier using the pin mod....as you can change your multiplier by the L1 bridges anyway...(even for mobos with no multiplier support, you an still close some and leave some open, and you will get a multiplier) not any bridges though..
i had a link for a site which tells you which L1's to connect to get a desired multi, but i seemed to have lost it...ohhhh well... :(

"user still has to close the L1s else there's no connection to the Multiplier signal busses."

I think his edit answers your specific question more directly.
