    I have 4GB on my iMac (Late 2009). I'd like to upgrade to 8GB. There are 4 slots, 2 have 2 GB DDR3 1067 Mhz each, the other two are empty. What's the best way to get to 8GB? Do I add two 2GB's or do I replace what I have with two 4 GB's? What is a good brand to buy and about how much should I expect to spend? Also, how do I make sure I got the right kind of memory for my Mac? Is it just DDR3 1067Mhz or is there more to it? Thanks!

    Best way is to add two more 2GB. 2GBs are cheaper and if your goal is only 8 GB then adding super cheap 2GB is better. If your goal is 16 GB then add 2 4GB chips and run with 12.

    2x4GBs are only 40-50 bucks for a matched set.

    Question about your recommendation imac model 10,1 updgrade

    I have the exact configuration as the original question with your response above….
    Is there any disadvantage to mixing up the 2 2GB with 2 4GB? Seems like I heard they slots work best with equal numbers. My goal is to get the max RAM of 16 GB which would mean purchasing all new 4 X 4GB. However, if it is significantly less money to add the 2 X 4GB and have a total of 12GB I would consider that if the performance is comparable.
    I am clueless on this.
    Thank you!
