Targeted Dell Laptop Upgrade

This 16 GB DDR4 SO-DIMM is built for Dell Inspiron 15 3593, Inspiron 17 3793 and Inspiron 17 7790 2-in-1 models. It delivers a single 16 GB module rated at 2666 MHz with CL19 timing and 1.2 V operation. The 260-pin unbuffered design fits directly into the factory memory slot.

Not for Other Platforms

Buyers who need memory for a different laptop brand or a desktop motherboard cannot use this module. The 260-pin SO-DIMM form factor and the validated compatibility list limit installation to the three Dell Inspiron series named above. Systems requiring ECC or registered memory should look elsewhere.

Speed and Capacity Gate

The decisive specification is the DDR4 2666 (PC4 21300) rating combined with a single 16 GB rank of 2Rx8 chips. If the target laptop supports 2666 MHz and has a free slot, this stick will run at that speed; otherwise the system will downclock to the lowest common denominator.

Questions about this item

Does the CM2048642666SO stick ship alone or with tools and manuals?

The package contains one 260-pin DDR4 SO-DIMM module and nothing else; no tools, cables or documentation are included.

My Inspiron 15 3593 has two slots and a 32 GB limit — should I buy one 16 GB module or two 8 GB modules?

One 16 GB CM2048642666SO fills a single slot and leaves the second free for a future upgrade to the 32 GB maximum.

The sticker says 2666 MHz CL19 — what speed will it actually run at inside my Inspiron 17 3793?

It will operate at 2666 MHz CL19 provided the processor and BIOS support that rate; otherwise it down-clocks to the highest speed the platform allows.
