8GB DDR4 2666 SO-DIMM Laptop Memory

This 8GB DDR4 2666MHz CL19 module uses a 260-pin SO-DIMM form factor and operates at 1.20V. It is an unbuffered, non-ECC memory upgrade built with major brand chips for laptop, notebook and all-in-one systems.

AMD & Intel Compatible DDR4 Upgrade

The module suits owners of compatible AMD or Intel laptops needing an 8GB DDR4 2666MHz replacement. Buyers whose systems require ECC registered memory, a different voltage, or a higher capacity per slot should look elsewhere.

DDR4 2666MHz PC4-21300 Speed Rating

The decisive specification is the DDR4 2666 (PC4-21300) speed rating combined with CL19 latency; the system must support this exact data rate and timing for the module to function correctly.

Questions about this item

Should I pick this single 8GB stick or add a second one for dual-channel?

This module is a single 8GB DDR4 2666MHz CL19 SODIMM. Adding a second identical stick enables dual-channel bandwidth on platforms that support it, doubling throughput for integrated graphics and memory-bound workloads.

What does the 2666MHz rating deliver in everyday use?

At DDR4 2666MHz (PC4-21300) with CL19 latency, the module runs at the JEDEC standard speed for many recent laptops, giving snappy application launches and smooth multitasking without overclocking.

Will the 260-pin DDR4 SODIMM interface limit performance on my laptop?

The 260-pin DDR4 SODIMM form factor is the standard laptop interface; it carries the full 2666MHz signal at 1.2V, so the slot itself does not cap the module’s rated speed.
