16 GB DDR4 SODIMM kit

This 16 GB kit contains two 8 GB DDR4 SODIMM modules running at 2666 MHz with CL19 timings. The unbuffered, non-ECC memory operates at 1.2 V and uses a 260-pin form factor. It is designed for notebooks or small-form-factor systems that accept DDR4 SO-DIMMs.

CL19 latency at 2666 MHz

The modules are rated for a CAS latency of 19 at the rated 2666 MHz speed, expressed as 19-19-19 timings. This single timing figure determines how quickly the memory responds to read commands. Systems will run all installed memory at the slowest module’s speed, so matching this latency matters for consistent performance.

Dual-channel upgrade for compatible laptops

Installing the pair in matched slots enables dual-channel operation on platforms that support it. The kit requires a 64-bit operating system to address the full 16 GB capacity. Because the modules are unbuffered and non-ECC, they suit standard consumer notebooks rather than servers or workstations that demand registered or error-correcting memory.

Questions about this item

What total capacity does the 2666 MHz kit provide when both modules are installed?

The kit supplies 16 GB of DDR4 memory across the two 8 GB SODIMM modules.

The modules are listed as PC4 21300 — what does that rating cap in everyday use?

PC4 21300 denotes the peak DDR4 2666 transfer rate; the system will run at the lowest speed among the CPU, motherboard and any other installed memory.

Will these 260-pin SODIMMs fit a standard laptop memory slot?

Yes, each module uses the 260-pin DDR4 SODIMM form factor used by most current notebooks and small-form-factor PCs.
