ASUS-compatible DDR4 SODIMM upgrade

This 16 GB DDR4 module is built for ASUS laptops and all-in-one PCs that accept 260-pin SODIMMs. It delivers a straightforward capacity increase for everyday workloads and light multitasking. The unbuffered, non-ECC design matches the memory architecture used in many mainstream ASUS systems.

CL19 latency at 2666 MT/s

The kit runs at 2666 MT/s (PC4-21300) with a CAS latency of 19 cycles at 1.2 V. This timing is the primary specification that determines whether the module will operate at its rated speed in your specific ASUS platform.

Suits single-slot upgrades on supported ASUS models

Buyers with a free SODIMM slot on a compatible ASUS laptop or AIO can add 16 GB in one step. Systems that require ECC, registered DIMMs, or a different pin count should look elsewhere.

Questions about this item

How much bandwidth will the DDR4 2666 CL19 module actually deliver in my laptop?

The module runs at 2666 MT/s with CL19 latency; real-world throughput depends on the platform's memory controller and whether it runs in single or dual-channel mode.

What does PC4-21300 mean for this SODIMM's speed ceiling?

PC4-21300 is the JEDEC designation for DDR4 2666; it sets the maximum data rate at 2666 MT/s and the module will not exceed that speed.

Will this 260-pin SODIMM fit my ASUS laptop's memory slot?

Yes, the 260-pin DDR4 SODIMM form factor matches the slot used in compatible ASUS laptops and all-in-one PCs.
