need some slot-1 info

[OrganizedChaos]

i've got a celeron 366mhz slot-1 processor that i want to underclock/undervolt, i've got the voltage problem all figured but intels datasheets aren't being very helpful on which pins control/lock the multiplier if any. can certain pins be cut/shorted to trick the motherboard like the voltage? a bios hack maybe? do slot-1 processors have the frequency multiplier on the motherboard or is it built into the chip? if its on the motherboard can i hack at it from there? the fefault multiplier is 5.5, i'm lookin to lower it to about 2.0 and bring the voltage doen from 2.0 to 1.5 maybe lower.

As far as I know, that's hard-coded into the Intel CPUs and can neither be raised nor lowered except if you have an engineering sample instead of a production CPU. On the older Intel boards where I've tried to change the multiplier, I've been graciously ignored by the mobo and it just does its thing anyway.

Bigger picture: what is your goal here? Trying for less heat output? If the board takes the Celeron II's, such as the 533A, 566 and on up, those have low heat output. The slot-1 versions of them could be a little hard to find, but you can park a socket version on a slocket and gain easy voltage control in the bargain. HTH

mechBgon is right i had the same problem with my p2 you can not change the voltage.
