The dual 1.25 will work fine in a single 1.25 motherboard. I don't believe it will harm the motherboard. A number of years ago I did have a dual processor where each processor was running a different speed. An error on my part. It was my first try at overclocking and I somehow skipped part of the

The reason I suggested this is that he's not going to run MacOS in this machine and the OS he's going to use won't use the second processor at all. CHUD won't work in a non MacOS machine. On Mar 9, 8:17 am, Jörg Duurkoop wrote: > Hi, > > > Your dual 1.25 will have a 2mb cache while the single wil

You can easily swap CPU modules between MDDs with the same bus speed. You can also do it between MDDs with different bus speeds but you need to do some resistor mods to get the best results or in some cases to work at all Taking out a dual 1.25 and replacing it with a single 1.25 is just plug and

Since all the smart people hang out on this list, having kept their G3 to G5 Mac computers, I thought this would be the best place to ask for help with this question I own a dual 1.25GHz G4 PowerMac MDD (FW400, not FW800), that I have upgraded to a stock Apple dual 1.42GHz G4 CPU module. My ques
