What core and bus speed is the 1.1? What make and model is the motherboard you're using?
If the 1.1 is tualatin core, then you probably are out of luck.
I think the coppermine p3 only went up to 1ghz anyway, but celerons went up to 1.1ghz.
If the chip has a large metal heatspreader on top, then its probably a Tualatin, whereas an exposed core would be copermine.
Give us a bit more info and we'll problaby be able to help more.
