Kingston memory for iMac ?

[mysticav]

Hi,

I have a
iMac 2.5Hgz Intel Core i5
4 GB 1333 Mhz DDR3

I want to expand to 8GB. As far as I know, I have 2 free slots available on my mac. So I would like to buy 2 modules, 2GB each.

Mac sells each memory module at 150 USD.

Apparently. this is an alternative:

I would like to know if I can use the kingston memory and if I can combine it with the current mac memory modules already installed.

If so, why the mac price is so high compared with kingston ?

Thanks.

You can use Kingston (or any other brand for that matter) in your iMac along with the stock memory. However, that link will not work, as it is the wrong physical size for your computer. One of these will do the trick for you. Apple just rips you off for upgrades you do through them. Definitely pass on RAM upgrades from them, and you also don't need memory labeled with apple or mac compatible, it's all the same.

I really appreciated your help. I will save more than 200 bucks. But just one question, the size you are recommending me looks very different as the one apple is suggesting me to buy for my iMac:

Can you please help me out with this ?

As far as I know, there's 3 sizes?
SO-DIMM for MacBook Pros, MacBooks and iMacs
regular DIMM is for desktop PC
and I believe there is a Server version for servers and Mac Pros.

SO-DIMM is the one I linked to which is the right size for Macs. However I'd do a bit more research as I've heard some memory is incompatible. Someone on here might know more on that one I posted.
