Is this for a single 2GB module? Or is it a 2GB kit of (2) 1GB modules? I have two slots, so I need 2 modules, of 2 GB each (for a total of 4).

It's one (1) single module of 2GB capacity. If you want 4GB then buy two (2) each.

It's a single 2GB module. I only had one spare slot, outside what my computer came with, and that's where I added it.

Each stick is 2 GB for a total of 4 GB, if your motherboard supports dual channel memory then yes, if it don't then you would just run single channel memory but use both sticks, I hope I didn't confuse you, either way you can use these memory sticks if your motherboard supports it, be sure to check the voltage as some motherboards are not very flexible about it.

Mine came with 2 x 2Gb memories, it has two slots so you may buy a 2 x 4Gb kit and replace the actual memories

Yes, these are 2x1 GB stick/order. And you should check your Mainboard for sure that you have 4 memory slots. Some Mainboard has only 2 slot for them. good luck!

This is a pack of two 4gb sticks of ram. (remember it is best with performance in mind to get paired sticks for desired results)

Those are actually a pair of 4GB modules. If you you buy two of them, you would get the 16GB you aiming at. The only downside is that, since mid-2010 iMacs have only 4 memory slots, you'll have to ditch the two 2GB modules that originally came with your machine. You may want to consider keeping the original modules and add only one pair of 4GB modules, to a total of 12GB, if it's not crucial for you to reach 16GB.

yes,from 4gb to 8gb of ddr2,now 1gb on each slot to 2gb on each.It has 4 slots totals,thanks.

I was wondering the same thing . . . and can you just add a 1GB chip in that additional slot?? We have one arriving today -- so I'll check out the documentation.

You can use up to 2 GB per slot, so the max would be 8 GB (up to PC2-6400 speed), I have not tried 4 GB memory in one slot, it may work, but isn't officially supported.

Thank you very much, Jose. Very helpful response! I was hoping it had room for 2 modules, but might go ahead with it any way.

It is one module, But: It can only take a total of 8GB of RAM. I read Dave's comment (no offence Dave) and bought two banks of 8GB and it only recognized 8GB if it. Called Technical Support and they verified it can only handle up to 8GB. So now I have one bank of 8 in the puter and one bank of 8 and 4 in my drawer; can't nave to much backup memory:)

I'm with Jeff S....you are going to want to put memory in pairs, so I would only recommend 12gb if you find 2x6GB chips. A 16GB kit (2x8GB chips) are pretty reasonably priced at this point, so that would by my recommendation.

Yes it has an extra slot... and yes it only has in a single stick of 2gb.... think it was a nanya... just buy a 4gb kit and sell the stick in it on ebay... I bought two when i was buying mine... so one upgraded the other and i bought a another 4gb kit for mine...

I checked the specs of your computer, you have a max load of 4gb. With 2 cards in there now it should be 1gb. So if you have 2 slots left, you could get bigger cards of 1gb for all slots depending in how much you need. Your serial shows its unbuffered ram. Look for PC2-4200 ram or DDR2 240pin SDRAM.Should be 533Mhz for speed. This is critical.

Got one soldered slot with 4gb stick and one that can be upgraded up to 8gb (in that slot), with 12gb total.

I would assume you could if you put that single card in slot one, but as far as going for more than 32 gb, that would be an experiment, I'd be interested in knowing the answer to as well XD
