Other World Computing Announces First–to–Market 64GB Memory Upgrade for Late 2015 27" iMacs

Addition of 64GB upgrade kit expands memory capacity to twice that of what is available from Apple

Oct 15, 2015 | Woodstock, IL


Other World Computing (OWC®), a leading zero emissions Mac and PC technology company, announced today that it has expanded its MaxRAM memory upgrade options for the newest Apple iMac 27" with Retina 5K display (Late 2015 iMac) to the maximum capacity of 64GB, twice the capacity of the factory–available options of up to 32GB.

After being the first vendor to provide aftermarket memory options for the new 27" iMac, OWC now offers the OWC MaxRAM Certified Upgrade kit of 64GB. This option provides buyers of the new iMac with greater choice, performance, savings and flexibility in their memory configuration choices.

The new OWC memory modules and kits are fully tested, qualified, and MaxRAM Certified for the most demanding applications. Additional memory is the most cost effective way to increase system performance. For applications that will benefit from more than Apple's current factory maximum of 32GB of total memory, new 27" iMac users will see improved performance gains with more memory provided by the new OWC options of up to 64GB.

OWC Testing Reveals Support for More Memory in New iMacs
The new Late 2015 iMac line was announced October 13, 2015 by Apple, and OWC was able to conduct testing of the computers to confirm they are able to support a maximum of 64GB of memory. New iMacs come with a standard 8GB of memory (two 4GB 1867 MHz DDR3 SDRAM memory modules), with the maximum amount of memory available from the factory consisting of four 8GB modules for a total of 32GB. From reading clues prior to the launch of the new iMacs, OWC suspected that the new 27" iMac would be able to support 64GB of memory, and testing of units purchased direct from an Apple store confirmed that suspicion.

Savings of up to 66% and up to Twice the Memory Possible Versus Comparable Factory RAM Upgrades
The new 27" iMac memory options are available at Upgrade kits up to 32GB that utilize the 4GB and 8GB memory modules are now available for shipping.
