Apple iMac 27" 5K Mid 2020 DDR4 SODIMM Kit

This 16 GB kit contains two 8 GB DDR4 2666 CL19 modules built to the 260-pin SODIMM form factor. It is made for the Apple iMac 27-inch Retina 5K Mid 2020 and matches the factory speed, voltage and latency of that system.

Upgraders with user-accessible memory slots

Owners of the supported iMac who want more capacity for multitasking, creative applications or virtual machines can install this pair without configuration changes. Builders working on any other platform, or anyone needing ECC, registered modules or a different DDR generation, should choose a kit validated for their hardware.

260-pin DDR4 SODIMM at 2666 MT/s with CL19 timing

The modules run at 1.2 V, are unbuffered and non-ECC, and use a 2Rx8 organisation. If your Mac requires this exact pin count, speed and latency the kit will slot in and be recognised immediately.

Soalan tentang produk ini

Will these DDR4 2666 CL19 modules run alongside the original memory already in my 27" iMac 5K Mid 2020?

Yes — the kit matches the iMac's DDR4 2666 specification and uses standard 1.20 V JEDEC voltage so it will operate with the factory-installed SODIMMs.

How can I confirm the 2x8 GB kit is running at the correct 2666 MT/s speed and CL19 latency after installation?

Open About This Mac and click System Report; the Memory section will show each 8 GB module at 2666 MHz with CAS latency 19.

What exactly ships in the box and is anything else required for the upgrade?

The package contains two 8 GB 260-pin DDR4 SODIMM modules; no tools, cables or additional parts are needed for the iMac's user-accessible memory compartment.
