Imac 2021 Memory Slots

With the advent of the larger screens, Apple doubled the number of memory slots from two to four. Consequently, the maximum memory capacity was also doubled (to 16 GB), and for Intel Core i-series (27-inch), quadrupled, to 32 GB.

If you have a recent model 21.5-inch iMac and are looking to boost its performance, OWC now offers a 64GB RAM upgrade kit. The kit is compatible with 2017 and later models of the smaller iMac, including the Retina 4K display model …

  • The 27-inch iMac has four memory slots and comes with at least 8 GB of 2666 MHz DDR4 memory installed. The more memory you choose, the more apps you can run simultaneously with a higher rate of performance. More memory (RAM) increases performance and enables your iMac to perform better and at a higher speed.
  • Among the moves the company has in mind: bringing back the SD card memory slot to this year's MacBook Pro. The upcoming MacBook Pro is an example of Apple’s renewed focus on Mac loyalists. The company is planning to bring back an SD card slot for the next MacBook Pros so users can insert memory cards from digital cameras.

This allows 21.5-inch iMac owners to max out their machines.

Continuing in the tradition of being first to certify and deliver DIY upgrade solutions for Mac owners, OWC is pleased to provide these high-performing memory kits to their customers making it possible to max-out upgradeable memory slots, allowing owners to boost performance levels to run more apps, work with larger files, speed up render times, and manipulate larger data sets.

As you’d expect, the 64GB RAM upgrade kit isn’t cheap, at $899 for the complete kit (with tools included) or $895 for the RAM on its own – but it still represents a 36% savings over Apple’s own pricing. OWC will also let you trade in your old RAM to further boost savings. If you’re upgrading from 32GB, you’ll get $180 back, and you have 60 days to mail in the RAM to receive your rebate check.

Professional Installation Highly Recommended. While this upgrade kit itself should not void your warranty, the installation process is very complex and thus it is recommended to be performed by a trained professional.
