Problem installing memory in Power Mac G5 (late 2005)

Hi, and a warm welcome to the forums! 🙂

That appears to be the correct RAM For the Quad & other 2 Dual Core G5s, but...

1. It's not working.

2. It must not be seated properly, the locking tabs must engage.

Also, just checking but are you aware they must be installed in opposing pairs? 1 with 1 2 with 2, etc.?

4-3-2-1*1-2-3-4

Pictorially, from BD's explanation:

Get the whole manual for your machine at

Power Mac G5 User's Guide (Manual)

on the support pages.

Thank you so much for your replies!

I should have mentioned in the original post that I did check out the manual, the apple support instructions, and watched a few videos before attempting the installation. I also checked the forums for a similar issue before posting because I can imagine how irritating it would be to get the same question for the 1238th time.

Thanks BDAqua!

I'm glad to know I purchased the correct RAM. I still don't know why the tabs did not engage--I tried everything I could think of. Anyhow, that doesn't seem to be something you folks can help me with. I'll try again.

As for Q1, I wasn't clear in my original post--there are three sets of chips involved. One set is in the first set of slots (using the numbering system in old comm guy's diagram) that is working. The second set is in the second set of slots and is not recognized by the computer. The third set is the new set I purchased that i was trying to install in the third set of slots.

In any case, I think what I'll do is take the second set out and try to install the third kit in that set of slots. Thanks again for your help.

But who's counting? 🙂

Anyway, I found that at least on my earlier machine, it was necessary to lay the machine on its side, as the Apple Service Source information suggests to techs, to insert the DIMMs without a fight. That's a little secret they didn't share with the general public (thank you very much Apple). When I did that, they went into the slots without a fuss, whereas when upright, the computer was resistant to inserting the DIMMs. Why that should be the case, I don't have a clue.

Ha! Thanks! 🙂

Thanks for the tip--I did try laying the machine on its side because it was recommended in a video. I'll just try again. It really seems like they should just go in! Maybe I just don't have the right touch... *sigh*

I hear you on the "touch" issue. IMHO, the DIMM connectors on my G5 were the most resistant connectors of any machine I have ever dealt with. At least on its side, the machine was a little more receptive. I didn't feel the need for a baby sledge to get the DIMMs in, but they definitely were not ZIF, either.

BTW, it's nice to see someone ahead of the game, as opposed to behind the curve. 🙂

Thanks again, old comm guy. I try!

Good to hear they're weren't ZIF for you either--I'll put a little muscle behind it next time. I probably won't get around to it until tomorrow, but I'll post again when I do.
