System-specific DDR4 SODIMM kit

This NEMIX RAM kit supplies 16 GB of DDR4 memory as two 8 GB SODIMM modules. The sticks run at 2400 MT/s with CL17 latency at 1.2 V. They use the 260-pin form factor and are built with unbuffered, non-ECC chips from major OEM suppliers. The kit is designed as a direct upgrade for compatible Apple iMac all-in-one desktops.

Suits iMac owners needing 16 GB at 2400 MT/s

This kit fits users who want to raise an eligible iMac to 16 GB using matched 8 GB modules at the specified speed and latency. It will not suit buyers who need ECC error correction, registered modules, a different pin count, or a higher total capacity than 16 GB. Systems requiring DDR5 or a faster DDR4 grade should look elsewhere.

Deciding spec: 260-pin DDR4 SODIMM at 2400 MT/s

The 260-pin DDR4 SODIMM interface at 2400 MT/s is the single specification that decides compatibility. Only Apple iMac models that accept this exact pin layout, voltage, and speed will recognise the modules. Verify the system documentation for 260-pin DDR4 2400 support before purchasing.

Questions about this item

Does the kit contain two 8 GB modules or do I need to buy a second stick?

The package includes two 8 GB SODIMMs for a total of 16 GB, so no extra modules are required.

Should I choose the DDR4 2400 CL17 kit or the DDR4 2666 ECC version listed in the model field?

Select the DDR4 2400 CL17 kit; the 2666 ECC entry is a different specification and is not compatible with this non-ECC unbuffered upgrade.

What does the 2400 MHz rating mean once the memory is installed in an iMac?

The modules will run at 2400 MHz with CL17 latency at 1.2 V, delivering the rated PC4-19200 bandwidth in supported iMac models.
