RAM question

[cain772]

Can I mix two different sizes together? My iMac Retina has four slots for RAM and it came with 2 4 GB sticks. Can I put 2 8 GB sticks or does it have to be of matching size?

Yes, you can mix them.

Yes, you can mix different sizes of memory. But for best performance, it is always best to use identical sizes.

Performance shouldn't be affected by using different sizes as long as the RAM is in matched pairs.

There is a slight performance benefit (around 5%) in using matched pairs of RAM. However, if you have two sets of matched pairs, (2x4GB and 2x8GB), you still get that benefit, even if the two pairs are not the same size. If you actually need and will use the added RAM, the increase in RAM will outweigh any benefit of using matched pairs.
