16GB DDR4 2133MHz SODIMM Upgrade

This A-Tech module adds 16GB of DDR4 memory at 2133MHz with CL15 latency. It uses the 260-pin SO-DIMM form factor and runs at the standard 1.20V. The kit is built with major-brand chips and is tested for reliability in laptop, notebook and all-in-one systems.

Compatibility and Limits

The stick is unbuffered and non-ECC, so it fits consumer laptops that accept standard DDR4 SO-DIMMs. Systems that require ECC or registered memory cannot use this module. Buyers should confirm their device supports 2133MHz DDR4 and has a free 260-pin slot before ordering.

Deciding Specification — Single-Rank CL15 Timing

The module operates at CL15 latency with a 2Rx8 organisation, which determines whether the memory controller can run it at the rated 2133MHz without down-clocking. If your platform only supports tighter timings or a different rank structure, the DIMM may not reach its specified speed.

Questions about this item

Should I choose a single 16GB stick or a 2x8GB kit for my laptop?

This listing is a single 16GB module; add a second identical stick later if your board supports dual-channel.

Will the 2133MHz speed actually run at that frequency in my system?

The module is rated at 2133MHz, but the laptop's memory controller may downclock it to the highest supported speed.

What does the 260-pin DDR4 SO-DIMM interface mean for compatibility?

It fits standard DDR4 laptop SO-DIMM slots and runs at the DDR4 standard voltage of 1.20V.
