Hey,

My new iMac 27 Ultimate will soon arrive from apple with factory installed 8 GB RAM, which according to the apple store website consist if 2 x 4 GB 1333 MHz DDR3 ram.

I will upgrade this to 16 GB ram, but can't find Samsung ram in Denmark where I live.

So will try to get 2 blocks of 4 GB Kingston 1333 MHz DDR3 ram and hope they will work together with the factory installed ram from Apple.

I bought the 2 x 4 Kingston ram for $100 and can exchange them if they are not compatible with the iMac.

Anyone have any experience with Kingston ram in iMacs and mixing two brands of ram ?

I will make sure to install the same type of ram in each of the slots, so the Kingston hoes into the two left slots and the factory ram in the right two slots (or the other way around)

Cross my fingers this will work, so I get 16 nice GB's of DDR3 ram ;)

I put kingston into mine. Works well. Any ram that meets the specifications will work well.

Thanks for that info.

A bit excited though if I can mix 2 of the ram blocks from apple ( which for sure is not Kingston ) with the 2 Kingston blocks of ram.....
And if I should mount the 2 Kingston blocks in the right slots or the lower slots to have a greater chance of success with the ram upgrade ?

On my 2009 imac 27inch with a 3.06 C2d. I tried everything I could think of with ram.
1gb sticks with 2 gb sticks with 4gb sticks two company mix and three company mix..

hynix, samsung ,micron. were the stick makers


I was unable to do wrong. every combo worked with every program. Based on that I don't think you can go wrong. Right now I run it with two 1gb sticks and two 4gb sticks..

Samsung are the 1gb and hynix are the 4gb.

Problem is that all 3 ram makers you refer to ate the ones that Apple use as their ram supplier in the iMacs. I can't get these ram brands in Denmark - so have to stick with Kingston, Corsair, OCZ, G Skill or Crucial.

any ddr3 1333 204 pin ram will work. brand is irrelevant. Also hynix is nothing but rebranded kingston ram they produce for Apple.
 
21.5 i3 refurb

I just ordered a 21.5 i3 refurb with 4gb or ram 2x2gb. How many memory slots does an imac have and are they already filled with those 2 2gb sticks.

Although I guess technically thats incorrect -- since iMacs now support 32 gigs of ram.

But at $3200 for four 8 gig sticks, I dont think anyone is rushing to buy it.
 
Has anyone tried mixing speeds? I have:

2x2GB 1333 Installed (Default)

I want to add memory I already have:

2x1GB 1066

Has anyone tried this or think it'll work? Thanks!
