OWC®, a leading zero emissions Mac and PC technology company has confirmed support for 128GB memory upgrades for the new 2019 27-inch iMac 5K; doubling the maximum factory offered memory, 64GB, in the 3.1GHz, 3.6GHz and 3.7GHz models and quadrupling it in the 3.0GHz, 32GB base model. OWC high-performing memory kits enable customers to boost performance levels and run more apps, work with larger files, speed up render times, and manipulate larger data sets.

Apple offers 32GB and 64GB memory options in the 2019 27-inch iMac 5K. OWC has certified and supports up to 128GB memory for all 2019 27-inch iMac 5K models, giving users up to four times the factory-available memory. This upgrade is exclusive to OWC and allows users to take new iMacs to their maximum potential, to create with endless possibilities.

OWC’s 64GB Kit also enables users to utilize up to two of the existing factory memory modules to upgrade to 72GB, 80GB, or 96GB depending on what memory is already in the iMac or they can trade in their existing memory for even greater savings on their OWC iMac memory upgrade.
