Want to overclock an old P200MMX. Is it possible?

[MANKOU]

I have an old Intel P200MMX on my second computer. Is it possible to overclock it? Changing the jumbers has no effect and I can't find something relevant in BIOS. I have heard that MMX processors are locked. Is it true?
Thanks in advance.

My old 166MMX went easily to 200MHz.

Nope, I just got a 200MMX and did a 75MHz FSB = 225 MHz

Got my 200MMX up to 250Mhz. Although by changing the FSB, which is running the PCI bus at 41Mhz.. it runs rock solid.

There are MMX CPU that are locked and unlocked. Looks like you've got one that is locked, overclocking still possible however, but your motherboard must support selective FSB frequency.

Which apparently does not. Thanks.

250 is really the max for the 200.
be happy if you can get 225 out of it.

I got it up to 266Mhz. Actually more like 263Mhz beacuse it was at 3.5*75Mhz using 2.9Volts.

I have a computer running 200mmx@233. Had to increase the voltage a smidge but it runs fine.
