ASUS DDR4 2666 SODIMM 8GB upgrade

This NEMIX RAM module provides 8GB of DDR4 2666 memory in a 260-pin SODIMM form factor. It is built for ASUS laptops and all-in-one PCs that require non-ECC unbuffered memory. The single-rank 1Rx8 design operates at 1.2V with CL19 latency.

Users with compatible ASUS systems

This upgrade suits owners of ASUS laptops or AIO PCs that accept DDR4 2666 SODIMM modules. It is not for systems that require ECC registered memory or a different DDR generation. Buyers who need more than 8GB per slot or a lower latency profile should look at something else.

CL19 latency at 1.2V

The module runs at CAS latency 19 with a standard 1.2V supply. This timing and voltage combination determines whether the memory matches the platform's supported specifications. Verify that your ASUS system accepts CL19 2666 SODIMMs before ordering.

Questions about this item

How can I verify the 8GB DDR4 2666 SODIMM is running at CL19 and 1.20V after installation?

Open Task Manager or UEFI/BIOS; the memory tab should show 2666 MT/s, 1Rx8 organisation, 1.20V and CAS latency 19.

What does the MS21300-818K1 kit contain and what extra parts are required?

The kit includes one 8GB 260-pin DDR4 SODIMM; no additional modules, tools or cables are needed for a compatible ASUS laptop slot.

Should I choose the 8GB 1Rx8 CL19 version or a different capacity for my ASUS laptop?

Select this 8GB 1Rx8 CL19 module when your system supports a single 260-pin DDR4 2666 SODIMM; match the existing rank and voltage if adding to populated slots.
