processor running under speed

[ricjamlew1]

I've got an old Gateway P5-166 machine with an Intel board with the number 'E139761' on it.

It came with a Pentium 166Mhz chip in a socket 7 but I've got on old Pentium 200Mhz MMX chip and replaced the old processor with this one.

The system still runs but only at 166MHz. How can I clock it up to 200MHz?

Cheers in advance.

You have to change the multiplier jumper from 2.5X to 3X. Actually, that's all you had to do in order to overclock the 166 to 200 also.

try 75FSB x 3x or 66x3.5x
I would be supprised if you couldnt do that.
many 200's did 250+

Thanks for the info.

However, I've looked through some of the information about how to do this (change the multiplier jumper) but I can't work it out.

Is it a hardware job or should it be in the BIOS? I don't seem to have any relevant options in my BIOS nor can I see any jumpers on the board anywhere near the processor.

Cheers,
Richard

P1 boards are all jumpers (or rockers)
do you know what mother board it is?

OT, but...jumperless overclocking didn't show up untill the 440BX, correct?
