OWC Announces Memory Upgrades From 8GB to 32GB For 2012 27″ Apple iMac

Other World Computing announced today the immediate availability of the OWC Memory Upgrade Kits from 8GB to 32GB for 2012 27″ iMac models that began shipping recently. OWC’s kits offer memory configurations not offered by the factory as well as savings up to over $400 compared to same size factory options. Like all OWC Memory Upgrade Kits, a ‘how-to’ install video and OWC Lifetime warranty are included.

One of Easiest to Upgrade Macs Ever Produced

Unlike the 2012 iMac’s complex install process which requires removing the screen with a custom upgrade kit developed and offered only by OWC, the 2012 27″ iMac has been hailed as one of the easiest to upgrade Macs ever produced. A memory access panel on the rear of the 27″ machine ejects via a simple push button located above the power input. Adding more memory is a simple, several minute process of installing new modules into the memory slots and reinstalling the access panel. Therefore, Mac performance experts recommend selecting the least amount of factory installed RAM when ordering a 2012 27″ iMac.

Savings Up to Over $400 Compared to Factory Upgrade

New iMac owners seeking to max-out the RAM can select the $197.00 32GB OWC memory upgrade and save over $400 compared to the 32GB factory cost of $600. For even more savings, iMac owners can trade-in the two factory base 4GB memory modules.

OWC Memory Upgrades for 2012 Apple iMac 27” 2.9GHz/3.2GHz i5 Models and 3.4GHz i7 Model:

Add to existing 2 x 4GB factory installed modules for 16GB total memory. Offers 75 percent savings vs. factory installed 16GB option.

Add to existing 2 x 4GB factory installed modules for 20GB total memory. Not available as a factory installed option.

51 percent savings vs. factory installed option.

67 percent savings vs. factory installed option.

Up to 32GB Memory Also Available for 2010-2011 iMacs

Owners of 2010-2011 iMacs can add an OWC Memory Upgrade up to 16GB priced from $97.50 to the original factory maximum 16GB installed memory for a total of 32GB. With the benchmark proven ability of OWC’s memory upgrades and the horsepower of up to a 3.4GHz Quad-Core i7 processor, these relatively new iMacs can deliver serious graphics production, A/V editing, and other professional use performance rivaling that of a Mac Pro for far less cost.

It just makes financial and performance sense to select the base level of factory installed RAM when ordering a new 27″ iMac,” said Larry O’Connor, Founder and CEO, Other World Computing. “For hundreds less than the factory, you can select one of our upgrades to deliver the machine’s true potential and install it yourself with a memory access design so easy, the process can be done by nearly anyone.

  • hi am looking to up grade my iMac 27inch late 2012 3.2GHz intel core i5 memory 8GB 1600MHz DDR3 Graphics NVIDIA GEForce GTX 657MX 1024 MB can you help as running out of ram
    thanks Steve

  • As per the article above the price for 32GB RAM is $197 but when I click to buy, the price come up as $269. Could you please look into it.

    Also I was wondering when are you going to release the SSD upgrades for 2012 iMacs?

    Thanks, A

      • Thanks for posting the link to the article.

        However as Apple’s memory pricing is still the same, the percentage saving is your article should be updated. It’s 31% and 32% saving compared to 51% and 67% saving for 16GB and 32GB RAM respectively.

        I saw 67% saving at the time of ordering my iMac and just ordered the 4GB base model. Now will half the saving, I would have preferred factory installed Apple RAM and would have saved on express postage for the RAM as well.

  • It is fantastic how easy it is to upgrade the RAM os the iMac 27″.
    What I would like to do, though, is replace the hard drive by a SSD drive like the Mercury 6G.

    Is it possible to do that.

    The fusion option is a bit skinny on the iMac.



    • We haven’t tested specifically, but I don’t believe you can.

      According to Apple Support Pages:
      If you install an earlier (previous) version of the Mac OS X than what was included, your computer may exhibit unexpected behavior such as:

      • The trackpad or mouse may not respond properly
      • The computer may stop responding
      • Sleep/wake issues may occur
      • The display image may appear to “shrink” with black bars around it, may appear tinted, or have other issues
      • Loss of built-in audio
      • Loss of Bluetooth or AirPort functionality
      • May not start up past the Apple logo
  • I have new 27″ iMac factory installed with 16gb of ram. Can I order 2X8GBs and add to remaining 2 slots or do I need to replace what I have?

  • Can you give us an update on feasibility testing of SSD upgrades for the 27 inch iMac?

  • A second (200th?) request/nudge for SSD internally. Both blade and drive options please.

    Minimally, can you sell a “reseal” kit separately for the 27?

    I’m holding my memory upgrade order to get it all in one shot and can’t wait!

    Thanks gang!

    • The HDD/SSD compatibility testing is currently being performed. Once we finish the testing and can speak authoritatively on what works and what doesn’t, we will report our findings here on the OWC Blog. Believe us, we’re as excited as everyone in discovering the full upgrade paths of every new machine and as soon as we’ve confirmed that either an upgrade is possible, not possible, or possible with exceptions; we will post without delay. But until we’ve finished, we don’t make assumptions.

    • We have not fully completed our compatibility testing yet – just got as far as the memory confirmation as of yet. When we’re completed, we will post all of our findings here on the OWC Blog.
