16GB DDR4 2666MHz SODIMM

This A-Tech module adds 16GB of DDR4 memory to a compatible laptop or all-in-one system. It runs at 2666MHz with CL19 latency and standard 1.2V operation. The 260-pin SO-DIMM form factor fits mainstream notebook slots and uses major-brand chips for reliable performance.

Replaces slower DDR4 or smaller capacity sticks

Upgrading from a 4GB or 8GB module at a lower frequency will raise total memory bandwidth and reduce swapping during multitasking. The jump is worth it when your current system shows high memory usage in everyday workloads and the motherboard supports 2666MHz DDR4 SO-DIMMs.

Suits owners of listed Dell part numbers

Buyers with Dell AA075845, SNPCRXJ16C/16G or SNPCRXJ6C/16G systems get a direct-fit replacement. Users needing ECC, registered buffers or speeds above 2666MHz should look at a different module, as this stick is non-ECC, unbuffered and fixed at the rated frequency.

Questions about this item

Will the 260-pin DDR4 SODIMM fit my laptop's memory slot?

This module uses the standard 260-pin DDR4 SO-DIMM form factor and operates at 1.2V, matching the physical and electrical requirements of compatible laptop slots.

What is the correct way to seat the module so it locks in place?

Align the notch on the module with the key in the slot, insert at a slight angle, press firmly until the side clips click and the module sits flat.

When should I consider replacing this 16GB DDR4 2666MHz CL19 stick?

Replace it if memory diagnostics report errors, the system becomes unstable under load, or you need more capacity or a higher speed than 2666 MHz.
