Hey, I need an answer quick. I have a Mac Pro 2008 with a single quad-core Xeon @ 2.8GHz. I recently ordered this http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=F27D0DCDA5CA7304 RAM packagefrom Crucial. Will this work on my Mac Pro? I didn't realize until afterwords that it says 8-Core and that there's a 4-Core version of the RAM available here http://www.crucial.com/store/listparts.aspx?model=Mac%20Pro%20(4-core%20Xeon%205400%20Series)%202nd%...
So, will the 8-Core version work on my 4-Core version? I see that the model numbers are different. That's a bad sign.
Thanks a lot.

Both sets of RAm that you've identified have the same specification, so these will be compatible with your 4-core version. The different part numbers - the CT bit - are used to match the memory to the individual machine. Both have this spec:
You should see no compatibility issues.
Hope ths helps

I'm sorry if I'm hijacking this thread, but I have an additional question. I'm in unholymist's exact position. I bought this: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=18CCE4DBA5CA7304
For an Early 2008 Mac Pro Quad-Core Intel Xeon 2.8GHz.
After installing it, I can only get a maximum of 8GB if I put the new RAM in slots 1 & 2.
If I put the original RAM in slots 1 & 2 I only get 2GB.
The problem is that the computer is ignoring the RAM in slots 3 & 4.
What should I do?
