8GB DDR4 2666MHz SODIMM for Dell Latitude

This 8GB DDR4 2666MHz CL19 SODIMM upgrades Dell Latitude 15 5500, 5591, 5300 and 5501 laptops. It runs at 1.2V with 19-19-19 timings and uses a 260-pin unbuffered layout. The module is built for owners who need more memory for everyday workloads on these specific models.

Replaces slower or smaller factory modules

The stick replaces the original memory when the system shipped with less than 32GB total capacity across two slots. A jump is worthwhile when the current configuration leaves headroom below the 32GB maximum or when a single-channel layout limits throughput. It will not suit buyers who need ECC protection or registered DIMMs for server-grade error correction.

Simple slot insertion with matched-pair advice

Installation requires opening the service hatch, aligning the 260-pin edge connector and pressing until the clips engage. Mixing with existing modules forces all memory to run at the slowest installed speed, so a matched pair is recommended for best throughput. A 64-bit operating system is required to address more than 4GB.

Questions about this item

Does the 260-pin SODIMM fit the single memory slot on a Dell Latitude 5300?

The module is a 260-pin DDR4 SODIMM, the standard form factor for the Latitude 5300 and the other listed models.

What is the correct way to seat the module so the 260 pins make full contact?

Insert the stick at roughly a 30-degree angle until the gold edge disappears, then press down firmly until the side clips click into the notches on both sides.

When would the CL19 timing require a matching stick to keep dual-channel performance?

Adding a second 8 GB module with the same 2666 MHz speed and CL19 timing enables dual-channel mode; mismatched timings force all memory to run at the slowest settings.
