    I just bought a 27" iMac and store did not RAM upgrades. I just went to Apple website and RAM is super expensive. Can you suggest some compatible RAM? I am looking to add 2X4GB to already existing 2X2GB total of 12GB

    On the fence
    You just need 204-pin DDR3 1333MHz memory. No need to bother with anything with some sort of "for Mac/Apple" branding either. If you're in the US, any of these will work nicely.

    id also like to add as a side note 2009 imac with the 2.8 i7's will not only accept 1333 but will run at that speed too(there was a thread about this that i have been meaning to reply to but i cant find it, i pulled the trigger on it and its been running magically ever since). i suggest waiting for frys.com to have a sale on kingston notebook value ram because it is PERFECT for unibody imacs (at least the ones without fsb restrictions)

    Good find -- anyone know the difference or if there even is one b/t the Corsair above on Amazon and the one Newegg carries? Very subtle product ID difference -- CMSO8GX3M2A1333C9 (Amazon) vs. CMSA8GX3M2A1333C9 (Newegg) -- Corsair says the 'A' version is their Mac memory.


    The funny thing is the newegg Mac product ID doesn't even exist on Corsair's website search, and if you look there under Mac memory they don't list any 1333MHz -- only a 1066MHz product.

    Here's their product sheet on the Amazon listed sticks:

    Same specs, and $15 cheaper for the 'non-Apple' memory from Amazon w/ the $10 rebate. I've been burned by memory issues in the past and the time spent diagnosing isn't worth $15 unless it is pure marketing.....what else could be different?

    Edit: Newegg actually carries both. The 'non-Apple' version also has a rebate there:

    I did the same thing and installed them last night. Everything is working well, I am happy to report! I now have 12 gigs of RAM on my new iMac 27".

    Just picked up my iMac yesterday. I ordered 4 x 4gb sticks from Amazon at a whopping (sarcasm) $90 for Kingston 16GB of memory. The memory industry pricing has sunk to an all time low.


    I past on Corsair this time around as the first pair of modules i bought for my Mac Mini were bad and had to be exchanged.
