Unless your motherboard uses the Intel BX chipset, it may not be possible.
That's the first thing to check. Also, that overclock is best done with a
celeron, not a PII.

Basically, if you want to overclock successfully, you need to do quite a bit
of research, preferably make your own system. Overclocking is not for everyone.

how do i switch between 66 and 100mhz bus on compaq presario 4240es PII 333
?

i believe it may be overclocked to 500 when it should be 333 at 5*66 it
maybe 500 at 5*100

this is causeing it to overheat and freeze up, i backed off to a 3
multiplier and now it works underclocked and cooler but im not sure if its
at 200mhz or 300mhz. meanwhile i will try to rig up another fan for it

i find jumpers for multipliers of 3,4,5,6 etc but not for bus speed

any ideas

thanx john
