    Hi guys, quick question. I got my late 2013 iMac last week (27" 3.2ghz i5 with 1tb fusion drive)

    I only chose 8gb ram as standard as Apple charge way too much.

    I want to upgrade the ram, and was going to add 16gb more in addition to the standard 8gb to give total 24gb.

    These are my options:

    http://www.ramexperts.com/corsair-c...ddr3-so-dimm-1600mhz-1-35v-laptop-memory.html

    http://www.ramexperts.com/ddr3/lapt...dr3l-so-dimm-1866mhz-1-35v-laptop-memory.html

    http://www.ramexperts.com/corsair-c...-pin-ddr3l-so-dimm-2133mhz-laptop-memory.html


    They are all 1.35v so should all work fine. Which do you think will work best? I am thinking of getting the 2133mhz one, as it will simply be under clocked and should work better, also it is not too much more expensive than the 1600mhz one. Does anyone have any experience with corsair vengeance ram in an iMac 2013? Or any other suggestions of what is the best possible ram to add in addition to the 8gb Apple give?

    Thanks a lot

    Download the crucial system checker from their website. Run it and find out what is exactly compatible. Then shop elsewhere for a cheaper price.

    When it comes to Macs they can be temperamental with clock speeds so only use what's recommended and match whatever is already in the system.

    As for brand names like vengeance and all that *****. It's just marketing nonsense. Ram is Ram and don't for one second let anyone tell you otherwise, it's simply rebranded factory Ram in order to give system builders bragging rights. You'll get hardcore performance nuts arguing that different brands of ram make a difference but to be honest you'd never notice it in a million years.

    Just make sure whatever you buy has got a good return policy and warranty, Ram can go bad or be faulty but it doesn't happen too often.

    • Memory modules get finicky and may not function properly when under clocked.
    • 2133MHz CL11 memory at 1600MHz will be slower than 1600MHz CL9 memory in that same system.
    • And finally your Mac expects memory modules to fall within a certain spec range - if you get memory that falls outside that range you may have issues.

    Great thanks for the replies. So I think I will most likely go for the 1600mhz CL9 version. This should work perfectly as it fits all Apples spec. Does anybody else have any experience using this specific memory (http://www.corsair.com/en/vengeance...op-memory-upgrade-kit-cmsx16gx3m2b1600c9.html) combined with original Apple memory?

    Which is better, the Corsair or Crucial? Or any other recommendations?

    Thanks a lot
