8 GB DDR4 SODIMM for 2017 iMac

This module is an 8 GB DDR4 2400 CL17 SODIMM built for Apple iMac 2017 27-inch Retina 5K and 21.5-inch Retina 4K systems. It runs at 1.2 V without ECC or a heat spreader. The part uses major OEM chips and fits the 260-pin slot.

Suits single-slot upgrades on compatible iMacs

Owners adding memory to a supported 2017 iMac will find the correct speed, voltage and form factor here. Builders working on non-Apple laptops or desktops that require a different DDR4 speed, rank configuration or voltage should look elsewhere.

2400 MT/s DDR4 speed

The memory operates at DDR4 2400 (PC4-19200) with CL17 latency. If the target system demands a higher or lower data rate, this stick will not match the required specification.

Questions about this item

Which capacity should I choose for my iMac?

This module provides a single 8 GB stick; add one or more to reach the total memory your 2017 27-inch Retina 5K model supports.

What does the 2400 MT/s speed deliver in my iMac?

The DDR4 2400 rating means the memory runs at 2400 million transfers per second, matching the specification Apple used for these iMacs.

How does the 260-pin SODIMM interface limit performance?

The 260-pin DDR4 SODIMM slot caps the module at the advertised 2400 MT/s and CL17 latency; no higher speed or lower latency is possible in this form factor.
