are these "unbuffered" and "non parity?" I'm upgrading memory on mid2007 iMac.

I don't remember, however, I have a mid 2007 iMac 24" and this memory works perfectly and installed it with no issues whatsoever. I've been using the computer with this exact memory installed for months with no issues.

I'm not sure about part numbers, etc., but I upgraded from original Apple 1Gb to Kingston 2Gb. It was easy to do and my 2007 iMac has run well with no noticeable difference.

iMac uses 200-pin SO-DIMMs, which are basically laptop memory.Also, iMac uses unbuffered memory, which is not these modules.

I used it in my early 2008 iMac.Your manual should specify exactly which types of RAM your iMac can use. iFixit is also a pretty reliable reference.

These RAM sticks are for Servers or Mac Pro's. They are fully buffered DIMMS which do not fit in your typical home user's PC. They physically do not fit. You need to find Unbuffered DIMMs with the appropriate speed.

Not sure, worked fine in my mid-2010 iMac. I suggest going to Apple icon on your menu bar and under "About This Mac" is a pane that will give you the memory type. Make sure it matches before ordering.I was super-paranoid about getting the right one but it worked out okay for me. Good luck!!!!!!!!

Yes it is. You can always check owc.com for what ram is compatible for your mac

Check Apple support site. Look up your computer model. That's where I found the information regarding what to do with my particular model. Then I purchased the correct ram cards and everything worked as expected. Perfecto!!!

If you want to be positive about compatibility, click the Apple icon at the upper left corner of your screen. Then click "About this MAC" and look at what it says for "Memory" if you have 1066 MHz DDR3 or 1067 MHz DDR3 it is compatible. If not, it is not compatible and you will need to look for the unit with the same type of RAM and MHz.

If it is the same pair that I bought, then no. You have to be really careful finding the right ram for the older imacs. Try looking on ifixit.com to figure out exactly which ram will work with your year of imac.

I don't know what speed the processor is in your iMac or anything based on what you are saying but choosing imac (early 2008) and nothing else does seem to match with these chips.

I went to Computer Rennaisance and they had to run the serial # off my computer to determine what was compatible. They still had trouble matching me up with the right RAM so I would advise checking with Apple or Computer Rennaisance first.

I'm considering upgrading the memory- does anyone know where the cheapest and most reliable place is to buy compatible mac memory?

Yes, but check what speed you have in there already if you are adding memory to existingBuffered is slower than unbuffered but usually more sticks can be used.Dont think you can mix Buffered/UInbuffered but may be wrong:)Hope that helps a little:)

These are standard laptop memory with standard dimensions. We bought these for iMacs and work great.

iMacs don't use 240pin RAM from what I've heard. It uses 204pin RAM. Try Crucial kits, they make most Mac RAM.
