my new apple memory doesn't show up in About this mac. I verified that I have put it in correctly.


Any thoughts?

Is this a single new stick to complement an already-existing stick? Can you swap the sticks into each others slots to verify whether it's bad RAM or a bad slot?

It is a complement to an already existing stick, and yes I have tried that.

And you've verified that it is the RAM itself that's bad? If so, then contact Apple and have them exchange it for you.

I haven't verified that yet, it was delivered to me this morning. I don't think it's bad, its right for my computer, it hasn't caused and Kernal Panics

I'm confused. You said you tried swapping the sticks. What were the results of that? Are the sticks the same size or not?

Look in System Profiler under Hardware --> Memory to see if both slots are recognizing the RAM. If one slot isn't seeing any RAM (which should be the case if the About This Mac window isn't showing the full complement of RAM), swap sticks and see if the slot that's not recognizing the RAM changes. If it does, the RAM is bad. If it doesn't, the slot is bad. (All of this is assuming that you seat the RAM correctly each time.)

Well, if the RAM doesn't show up when placed in either slot it is most likely dead and needs to be replaced.

im glad a thread opened reguarding this problem..
im running a pbook, 1.67, stock 512 ram. i upgraded to 1.5g of ram. all works fine, when it boots up i check under system prof. and it recognizes the gig stick and the other 512 stick. After a while however, i check it again and it shows it as 512 in both slots, total ram equalling a gig.
is the machine just lowering it cause its not in use? it doesnt make sense.

Let me rephrase this all.

My Mac is not recognizing the ram. I trade the sticks between the slots and it still doesnt work
