16GB DDR4 2666 SO-DIMM kit

This 16GB kit contains two 8GB DDR4 SO-DIMM modules rated at 2666 MT/s with CL19 latency. The 260-pin form factor fits standard laptop memory slots. Black Diamond Memory supplies the modules as a matched pair for dual-channel operation.

Suits laptops needing 16GB at 2666 MT/s

Builders who need a different capacity, a higher speed grade or lower latency timings should look at other kits. Systems that require non-standard pin counts or a different DDR generation cannot use these modules.

260-pin DDR4 SO-DIMM interface

The 260-pin SO-DIMM connector is the single specification that determines physical and electrical compatibility with the laptop slot. Verify that the target system accepts DDR4 SO-DIMM memory before purchase.

Questions about this item

Should I pick the 16GB (2x8GB) kit or look for a single 16GB module?

The 2x8GB kit lets you run dual-channel mode on most laptops, which doubles the data path compared with a single stick and improves integrated-graphics performance.

What does DDR4 2666 (PC4 21300) actually deliver in my laptop?

The modules run at 2666 MT/s with CL19 timing; your CPU memory controller will set the final speed, often matching the rated 2666 MT/s if the platform supports it.

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

Yes — 260-pin DDR4 SO-DIMM is the standard form factor for DDR4 laptop memory, so it installs in any slot designed for DDR4 SO-DIMMs.
