Targeted iMac Memory Upgrade

This 8 GB DDR4 kit (2 x 4 GB) is built for the 21.5-inch iMac released in mid 2017. It matches the factory DDR4 2133 MHz specification and uses the 260-pin SODIMM form factor required by that model. The modules are non-ECC, unbuffered, and run at 1.20 V.

Drop-In Installation

Each stick fits directly into the iMac’s two SO-DIMM slots without adapters or configuration changes. The 1Rx8 rank layout matches the system’s memory controller expectations, so the computer recognises the full 8 GB immediately after the cover is replaced and the machine restarts.

Replaces Slower Base Configurations

The kit upgrades iMacs that shipped with 4 GB or 8 GB of slower memory, eliminating the bottleneck that appears when multiple apps or browser tabs compete for RAM. It does not serve machines that require ECC, registered DIMMs, or a different DDR generation.

Otázky k tomuto produktu

Does the 2133 MHz DDR4 speed limit bandwidth during sustained workloads?

The modules run at DDR4 2133 MHz (PC4-17000), which sets the maximum data rate for continuous use.

How much heat or power do the 1.20 V unbuffered SODIMMs produce when running all day?

At 1.20 V without a heat spreader, the 1Rx8 chips generate typical DDR4 SODIMM thermals for a 21.5-inch iMac chassis.

Which iMac model identifiers must the machine already show for this 260-pin kit to work?

The system must report iMac18,1 or match Apple order number MMQA2LL/A and model A1418 (EMC 3068).
