RAM It says 1 GB with single SO-DIMM. Is this correct? Apple's own store has it with 2x512Mb.

It is 2x512mb...(what apple's web site says). Unfortunately, that means when upgrading, you will need to replace both (not cost effective, I know).

Glenn Levy, you are INCORRECT. Unlike older iMacs, the RAM in Intel iMacs is a user installable part and does NOT void the warranty. I would recommend upgrading to at least 2 GB (1 GB is bare minimum these days). Anything you can do to reduce the amount of reading/writing to the hard drive will boost overall system performance.

Actually, up until a couple of days ago on Apples iMac 20" Customize your Mac page, it said in the learn more link under RAM to 'choose the 1x1GB stick if you plan on upgrading later' or something like that. I emailed them... in a hopeless attempt to get them to actually add the option but all they did was removed that part in the learn more section :(

Warning **** if you add or replace ram you automatically void your warranty. Also good luck getting aple service to do anything for you ever.

Awesome thanks, cuz I recently ordered some RAM and I got one that isn't compatible with the iMac. Thanks again

The specs I've read for your model computer suggest that RAM maximum is 16 GB, although Apple only recommends 8 GB maximum.

From About Mac info:4GB DDR2 SDRAMSpeed: 667 MHzMfr: 0x7F7F7F7F7F9B0000Part number is 0x0000... (All 0's)Serial:0xFFFFFFFFBut it doesn't matter about "matching" because you can only have 2GB in the second slot, so it will never match. Unless you have same size DIMMs, the computer won't divide the tasks per the "matched pair for slightly faster processing" concept.

Standard RAM on this model is 16GB, if you want 32 you either have to get a "build to order" unit from the Apple store or add third party RAM (very easy to upgrade) yourself. Apple upgrade is $400 and $300-350 or so from aftermarket sellers.

Not on mine--showed up as 2x2GB instead of 2x8GB. Went out and bought Mac memory and worked perfectly.

There is a page on Apple's website that may answer you question (http://support.apple.com/kb/HT1270?viewlocale=en_US#link1). Your Mac does not support 16GB of RAM, though 8GB are enough to run both these programs smoothly. This memory is not the right choice for your Mac, as it is (PC3 - 12800), and your Mac requires (PC3 - 8500).I've already searched the one that is just right, which is in this link: Crucial 8GB Kit (4GBx2) DDR3/DDR3L 1066 MT/s (PC3-8500) SODIMM 204-Pin Mac Memory CT2K4G3S1067M / CT2C4G3S1067M

it is a single 8GB, go to crucial.com and run the web scanner it will tell you want kind of RAM and what size for free. I put this in a HP.

It has 4GB permanently on the logic board, and I've gotten ti to take another 8GB DIMM, Giving me 12. Just be sure to match the bus speed!

I bought mine through Apple, so I customized it with 256GB of storage. I paid $1629, with the student discount, so if it's much lower then that, I'd say it's the 128GB version. Anyway, I'd trust the product description, if it says 128GB, that's what it is.

posted right in the details ------Memory: 2x DDR3-2133(OC)/1866/1600/1333/1066 DIMM Slots, Unbuffered, Max Capacity of 32GB------ yes

Someone mentioned in a review that there were two slots opened. So with there being four slots in total, you can safely assume that it is two 2gb dimms.

ram is 1 x 8gb..............there are 3 more spare slots , so you have 32 gb potential! ..........1 spare slot is under keyboard, other two are under base cover. be happy, and enjoy this beasty!cheeribye.......

I think it can take up to four gigs of RAM. Mine only came with one though.

There are (2) DDR3 SO-DIMM slots. Not sure on the limits per slot, but you should be fine at (2)x(8GB) SO-DIMM's for ~$90 extra. The default configuration is 4GB+2GB.

Check he details of your currently installed ram from the apple "about this Mac" menu. You should look at the 'memory' section and the new ram should match (all but the GB). I'd also check a few forums to see if they were able to upgrade the ram for your specific model. I would have thought it would be fine, however, I had to play about with mine a bit for it to accept the upgrade and actually show the ram installed. Hope this helps.
