The 1333 MHz DDR3 RAM dilemma...

Hi guys,

Yesterday I purchased a new iMac 21' with 2 TB HD and 8 GB of RAM- so I thought. Because of a screw up at the store, it came with 2x 2GB 1333 MHz DDR3 RAM. The store apologised and gave me 2x 4GB RAM to install.

Question 1: Will having mismatched RAM (2x 4GB & 2x 2GB) running together be counter productive or damaging to the computer?

Question 2: Is it worth selling the practically brand new 2x 2GB 1333 MHz DDR3 RAM or swapping to one 4GB?

Thanks for your patience!

I'm no mac expert, (I'm sure they will be along soon to advise you), but my 2010 iMac came with 4gig installed (2 x 2gig sticks). I've recently upgraded to 12gig, and got 2 x 4gig sticks.

So I'm running with 4gig and 2gig sticks together and it works tip top

keep the extra and run 12 gig in it

Answer to question 1: no, as long as all the RAM is 1333MHz DDR3.

Answer to question 2: depends on what you can get for it I suppose.
