8GB DDR4 2133 SODIMM for iMac 21.5" Mid 2020
This 8GB DDR4 2133 CL15 module is built specifically for the Apple 21.5-inch iMac released in Mid 2020. It uses a 260-pin SODIMM form factor, runs at 1.2V, and carries a CL15 latency rating. The kit suits owners of that exact iMac model who need a single-slot memory upgrade. It is not ECC or registered memory.
Replaces factory 4GB or 8GB DDR4 2133 sticks
The Mid 2020 iMac ships with soldered or slotted DDR4 2133 memory depending on configuration. This module matches the original speed, voltage, and timing so it works without BIOS changes. The jump is worth it when the system shows memory pressure during multitasking, virtual machines, or large creative projects. It does not add capacity beyond the board’s maximum slot limit.
Steady throughput at CL15 under sustained workloads
Unbuffered DDR4 2133 at CL15 delivers consistent bandwidth during long render, compile, or analysis sessions. The 1.2V operation keeps thermal output low inside the compact iMac enclosure. No heat spreader is fitted, so airflow from the system fans handles cooling directly. Performance scales linearly with the number of populated slots up to the platform maximum.

Preguntas sobre este artículo
Will this 260-pin DDR4 SODIMM fit the memory slot in my 21.5-inch 2020 iMac?
Yes, the 260-pin DDR4 SODIMM form factor matches the slot used in the 21.5-inch iMac from 2020.
What is the correct way to seat the module so the iMac recognises the full 8 GB?
Insert the SODIMM at a slight angle until the gold contacts disappear, then press down firmly until both side clips click into the notches.
Does this non-ECC unbuffered module need any firmware updates or battery replacements over time?
No firmware or battery maintenance is required; the module is a passive component that either works or fails, in which case it would be replaced.
