OWC has made memory kits available up to 128GB which is as much as four times the capacity Apple's configurations, at a lower price than Apple's RAM. Through OWC, users can jump up to 64GB for $579.99, 96GB for $749.99, and 128GB for $1099.99.
The new 27-inch iMac can be configured at time of purchase with up to 32GB or 64GB of RAM depending on your model. If you choose the 3.0GHz 6-core eighth-generation Intel Core i5 processor, the maximum from Apple is 32GB. The 3.1GHz 6-core 8th-generation i5, 3.7GHz 6-core 9th-generation i5, or the 3.6GHz 8-core 9th-generation i9 processor are limited to 64GB of RAM when purchased from Apple.
From Apple, upgrading from 8GB to 16GB, costs $200, with 32GB ad 64GB upgrades available for $600 and $1000, respectively. Using OWC RAM, 128GB sells for only $100 more Apple's cost for 64GB.
