  • Type260-Pin DDR4 SO-DIMM
  • Ready for 64 GB capacity across 2×32 GB modules
  • Runs at 2666 MHz DDR4 speed for quick data access
  • Low 1.2 V operation keeps system cool and efficient
  • CL19 latency timing supports responsive multitasking
  • Fits 260-pin SO-DIMM slots in compatible 2018–2020 Macs

64 GB DDR4 SO-DIMM kit for select Apple Macs

This 64 GB kit contains two 32 GB DDR4 2666 MHz CL19 SO-DIMM modules built to 260-pin 1.2 V specification. It targets owners of the 27-inch iMac models from 2019 and 2020 plus the Late 2018 Mac mini who want to reach the maximum memory capacity those systems officially accept.

Dual-rank modules and Mac-specific validation

Each 32 GB stick uses a dual-rank 2Rx8 organisation based on 1024 x 8 components. The supplier validates every module for voltage, temperature, signal integrity and macOS compatibility, and includes a note to wait 30 seconds after installation so the firmware can recognise the new memory.

2666 MHz DDR4 speed and 260-pin form factor

The modules run at PC4-21300 / PC4-21333 speeds with CL19 latency in the standard 260-pin SO-DIMM form factor. Systems that require a different DDR generation, a higher frequency, ECC or registered memory will not accept this kit.

商品問答

Will the 2×32 GB SO-DIMMs need any firmware updates or periodic reseating after installation?

No firmware updates or scheduled reseating are required; the modules are validated for voltage, temperature and signal integrity at the component level and carry a lifetime warranty from the purchase date.

What is the first limit reached when the memory runs at 2666 MHz CL19 under sustained load?

The JEDEC-standard 1.2 V operating voltage and CL19 latency are the fixed electrical limits; the modules are tested for stability at those parameters.

How much heat and power does the 64 GB kit draw when the iMac or Mac mini runs all day?

Each 32 GB module operates at 1.2 V DDR4 standard voltage; total power draw stays within the SO-DIMM slot specification and the Mac’s thermal design handles the heat.
