Apple Mac DDR4 2666 SODIMM kit

This 64 GB kit contains two 32 GB DDR4 2666 MHz SO-DIMM modules built for select Apple computers. It targets owners of compatible iMac and Mac mini models who want a straightforward memory increase.

260-pin DDR4 2666 specification

The modules run at DDR4 2666 (PC4-21300) with 1.20 V, non-ECC unbuffered 2Rx8 organisation and use major-brand chips. The 260-pin SO-DIMM form factor is the single detail that decides physical and electrical fit.

Suits listed iMac and Mac mini models

It matches the Apple order numbers and model IDs supplied for 2019-2020 iMac and 2018-2020 Mac mini systems. Buyers with other Macs, Windows laptops or desktops needing different speeds, ECC, RDIMM or other form factors should look at something else.

Questions about this item

How does 64 GB of DDR4 2666 memory change real-world performance in a supported iMac or Mac mini?

The kit adds two 32 GB SO-DIMMs running at 2666 MHz, giving the system more room for simultaneous apps and large files without swapping to storage.

What does the PC4-21300 label tell me about the module interface and its practical limit?

PC4-21300 confirms DDR4 2666 on a 260-pin SO-DIMM; the Mac’s memory controller sets the actual operating speed.

Will these 260-pin sticks physically fit the memory slots in a 2019 or 2020 iMac and a 2018 or 2020 Mac mini?

Yes, the modules use the standard 260-pin SO-DIMM form factor required by those iMac and Mac mini models.
