Hi, I just bought my i7 27" iMac and now I need RAM.
Which one do I need?

SO-DIMM 204pin DDR3 1333 ?
What do I have to look for?

Will this be the right one:

Corsair ValueSelect SO-DIMM Kit 8GB PC3-10667S CL9 (DDR3-1333)
?
 
nod here for crucial... but corsair is one of the best out there. been using corsair in gaming rigs forever without issue.

I also buy from newegg for components usually.

Thanks for the link, because I initially went to the "Mac" section of their memory browser, under which there were only 3 selections listed under their 204-pin 10600 sticks.

If you go through the "Laptop Memory" section, there's 31 different sticks to choose from.

I ended up picking the one you linked, as it has the most reviews, best reviews, and cheapest. What could be better?

And sorry for digging up a slightly old thread.

Be careful with that particular model. It seems to give my iMac random freezes. All memory tests are negative though. I am still unsure if its really because of the RAM, but the probability is there.

I'd suggest you go with Crucial, because they offer money-back on memory which you choose using their memory configurator tool.
 
I put 2 sticks of Samsung from Amazon in mine and it loves it.

Samsung 4GB

so this ram works for iMac even it's labelled as laptop memory?

are there any performance differences compared to crucial ram for instance?

iMac requires laptop memory. The performance characteristics of all cheaper brands are virtually identical, you should only really care about the brand if you plan to overclock.

excuse my ignorance, but what does overclock mean?
I probably will not since I don't even know what that means. :eek:

I guess $100 for 16GB ram from G-Skill is pretty good right?
 
is it ok to leave the 2 x 2gb that came with the system and just install 2 x 4gb in the 2 extra slots for a total of 12gb??

is there a problem with the system not running in dual channel mode ?

It will be running in dual channel mode. Two sticks of stock RAM = dual channel, two sticks of your RAM = dual channel. The RAM slots are pairwise matched.
 
ahhhh wtf i just paid 55 dollars other day for this i could have loved to get it for 30+ tax less nooooo
