System-specific 8 GB DDR4-2400 SO-DIMM

This NEMIX RAM module delivers 8 GB of DDR4 memory at 2400 MHz with CL17 latency. It uses a 260-pin SO-DIMM form factor and runs at 1.2 V. The stick is built for Apple iMac 27-inch Retina 5K models from 2017.

Suits owners upgrading a 2017 27-inch iMac

Buyers who need ECC error correction or registered buffering should look elsewhere, as this module is non-ECC and unbuffered. Systems that require a different pin count, voltage or speed grade will not be compatible.

260-pin DDR4 SO-DIMM at 1.2 V

The 260-pin DDR4 SO-DIMM interface at 1.2 V is the single specification that decides whether this module fits the target iMac. Verify the slot type and voltage before purchase.

Questions about this item

Is this single 8 GB module the right choice for my 2017 27-inch iMac?

The module is built to match the 2017 27-inch iMac's DDR4 SODIMM slot, so one 8 GB stick adds 8 GB of memory to the system.

Will the CL17 timing slow down everyday tasks on this iMac?

CL17 is the module's rated CAS latency at 2400 MHz; the iMac's memory controller uses that timing automatically, so performance follows the system's standard memory behaviour.

Does the 260-pin DDR4 interface limit the speed to 2400 MHz in this iMac?

The SODIMM is a 260-pin DDR4 device rated at 2400 MHz (PC4-19200), and the iMac's memory controller runs it at that speed.
