Old / New G5 issue..Memory slots showing as blank

[Kraniac]

I replaced my old G5 the other day with an old G5..same machine..sick, I know.

So, I took all the memory out of my old box and installed it in the new G5..all 8 slots.

I was careful to install properly, in pairs in like spots across the 2 groups of sockets.

System profiler is telling me that 2 slots are empty...they have chips in em.

I re tested the memory in the so called "blank slots" in slots that were showing as filled..swapping around and it is recognized in other slots, as well as in my old machine.

I know G5's have a reputation for this but Im wondering if there is a fix??

tried zapping the Pram but that's not even what zapping does..it's just cool.

sounds like 2 dead slots to me

Did you blow the dust out of the old/new machine before you installed the old/new RAM into it?

Can of compressed air on the motherboard and fans, focusing in/on the RAM slots, might get them working again.

I think the same thing happened to me when working on a mac pro. I took the RAM tray out and took a close look. There was a gigantic dust bunny in there. Blew it out and all was well. But there is a chance that the reason your G5 was up for sale was that it had bad RAM slots and the seller was hoping that no one would notice...
