this should work with any PLL on a laptop with this chipset but i can garuntee nothing, check your pinouts if your hav one i dont list.

this will get u 133fsb on a i855pm chipset (which does not hav this option normally)

for anyone interested short the 2nd and third pins on the IC chip under where the wireless card would be. basically under the touchpad. 2nd and third counting from the top left when the laptop is sitting in front of you normally, you would b able to look at the screen.

long discription. this is an actual clock generator alteration. it apears to hold normal agp/pci bus speeds but the memory bus increases. i had to drop back to using pc2100 (ddr266) memory to get it to set a higher memory divder, but even with that ram its running at actual 176MHZ (ddr352) as for the cpu i left the stock 1.4 ghz 100mhz cpu in, to run at 1861 on the new bus speed. idealy it could b replaced with a real 133fsb cpu, that may or may not generate an 'unknown cpu' error by the bios.

known working clockgen chips

PLL CY82346
PLL 950810PG

like i said, others conected to this chipset SHOULD hav the same pinout, but i cant be held resposible for laptop explosions, dead cpu's, ram, etc.

just so u knows im not talking out my ars.
