Capacity 8GB

  • 8GB capacity lets you run more apps simultaneously
  • DDR4 2666MHz speed loads programs faster
  • CL19 latency improves system responsiveness
  • 2V operation reduces power consumption
  • 260-pin SODIMM fits compatible Mac models

Compatible Mac upgrade

This 8 GB DDR4 SODIMM is built for mid 2020 and mid 2019 27‑inch iMacs and the late 2018 Mac mini. It uses a 260‑pin unbuffered non‑ECC layout at 1.20 V. The module targets owners of those specific Apple systems who need a straightforward memory increase.

Sustained workload behaviour

Rated at 2666 MHz with CL19 latency, the stick delivers steady throughput for long rendering, compilation or virtual‑machine sessions. The validated voltage and signal integrity keep data rates stable when the system runs under continuous load rather than short bursts.

Thermals and power draw

Operating at the standard 1.2 V DDR4 level, the module adds minimal heat inside the tight iMac or Mac mini enclosure. Low voltage keeps fan activity quiet during typical productivity work while the unbuffered design avoids extra power overhead.

Questions about this item

How much heat and power does the 1.2V DDR4 module draw when the iMac runs all day?

The SODIMM operates at 1.2V and is tested for voltage and temperature resistance, so it stays within standard DDR4 thermal limits during continuous use.

What must the Mac already have for this 260-pin DDR4 2666MHz stick to work?

A free SODIMM slot in a compatible 27-inch iMac (Mid 2020 or Early 2019) or Late 2018 Mac mini, each of which accepts DDR4 2666 SO-DIMM memory.

Will this CL19 2666MHz module run correctly alongside the original Apple memory in a 2019 iMac?

Yes, it matches the factory DDR4 2666 CL19 specification used in those iMacs, so it will operate at the same speed and timings as the installed modules.
