Sorry, I don't understand this sentence. … it is not possible to speed up for down speed a processor card ??? What is to speed up for down speed? Or did you mean: to speed up *or* down speed a processor card? This way the sentence would make sense to me. If so, I don't think you're right. It should be possible to put a Dual-1 GHz from a QS2002 into any QS2001 as it should be possible to put a Dual-800 MHz from a QS2001 into any QS2002. But… yes, I remember reading something about an incompatibility here. But I don't know why. So, the question still remains: why? (can't I put a QS2002 Dual processor into a QS 2001 and vice versa?) Anyway, I think it is well possible to change the speed of the processor card. > On uniprocessors, it is sometimes possible to change the speed > through adjustment of certain jumpers, which usually means removing > or adding a resistor, possible a "zero ohm" resistor (i.e., a jumper). Not only on uniprocessors: http://power-mac-g4.com/g4clockup.html Apparently you can also overclock a Dual-450 from a GE. And from what I've read somewhere (no link at hand) people are also overclocking their Dual-1 GHz machines… -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
