I've got a g5 dual 2.0ghz. I am about to remove one of the processors as apple have indicated that one is faulty.
My question is are they inter changeable and can the processor be removed from the heatsink as I want to re apply thermal paste to see if that solves problem, however a couple of sites have warned against separating processor and sink.
Jonathan.

Do not do this unless you have the original install disks with the fan syncing software or AHD. Some of these can run with just one processor. Yes the processors can be removed and changed. Would you tell us HOW Apple arrived at their conclusion?

Do you mean do not remove the processors at all if I haven't got the original disks? Or just processors from heat sinks?
If I haven't got original disks where could I get a copy of them?
An Apple reseller did a diagnostic and said that one of the processors was showing a fault. Apple themselves wouldn't even run the diagnostic as it is a 'vintage' machine.
I've also read reseating processors may help. What does this involve?
If you don't change anything the fans will be OK. You may even be able to disable one of the processors. The fan syncing software is on the Apple Service Diagnostic v2.6.3 I believe. Finding that software (which is for service providers) can be daunting as Apple seems to get rid of sources. It would be nice if you could find out just what diagnostic Apple ran and which processor was bad. They can work on vintage machines if they have an older tech. The younger guys don't bother to learn the older machines. Guess I shouldn't gripe, I don't work on Apple IIs anymore, but I can rebuild a power supply for a 1984 Mac +
The technicians that ran the diagnostic were very vague just said that when they ran diagnostic one of the processors was showing an error. I think they would prefer me to upgrade. I have disabled one processor but the machine froze again which is why I was wondering if they could simply be swapped over - as they are on separate heatsinks. Would this require re-syncing the fans?
I'll have a search for the diagnostic software later on. Thanks for the info on that.
If they charged you for this "diagnostic", I'd get my money back if they can't tell you how they arrived at their conclusion. They want you to upgrade because they don't know what they're doing. I wouldn't believe a word of it unless they can tell you exactly what they did and what tools they used. I'd find out before doing anything else.
I downloaded asd 2.6.3 but that's not comparable. Have tried to download 2.5.8 but dmg not complete. Do you know of any good sources for this?

They didn't charge me as they couldn't offer a fix. It did start behaving again for a few days but has started crashing again. I have disabled one processor and it still crashes so I think the problem is with the master processor. I don't feel I've got anything to lose from trying to re-seat the processor.

Disable the other processor first. As far as I know there is no "Master Processor".

I have only found instructions to disable one processor and I'm sure I read on one site that one processor is set up as master and one as slave. CPU pref pane will only allow me to disable one of the processors and not the other.
