What this memory kit does

This 32 GB DDR4 SODIMM kit contains two 16 GB modules rated at 2666 MHz with CL19 timings. It is built for the listed Dell Inspiron 15 3593, Inspiron 17 (7790) 2-in-1 and Inspiron 17 3793 notebooks. The unbuffered, non-ECC design runs at 1.2 V and fits the 260-pin slots in those systems.

What the two-module pack changes

Supplying two matched 16 GB sticks fills both memory sockets at once, letting the platform run in dual-channel mode for higher bandwidth than a single module. The kit is tested together so the pair initialises at the rated 2666 MHz without manual timing adjustments. Mixing these with existing modules will force all memory to the slowest installed speed.

Limits of the DDR4 2666 SODIMM interface

The DDR4 2666 standard caps transfer rates at 21300 MB/s per module, so total throughput cannot exceed that ceiling even if the processor supports faster grades. The 260-pin SO-DIMM form factor fits only notebooks and small-form-factor boards with matching slots; it will not install in desktop DIMM sockets. The 32 GB total matches the maximum capacity the compatible models can address.

Questions about this item

Will the CL19 timing or 1.2 V voltage require any future adjustment or replacement?

The modules run at standard 1.2 V with fixed CL19 timings; no maintenance or replacement is needed unless a stick fails.

What limits sustained throughput first on this DDR4-2666 kit?

The DDR4-2666 speed rating sets the maximum data rate, so the memory bus itself is the first ceiling under continuous load.

How much heat and power do the two 16 GB sticks produce during all-day use?

Each stick draws 1.2 V with no heat spreader, so total power stays low and the modules run cool in normal laptop airflow.
