  • Boosts system responsiveness with 16 GB DDR4 capacity
  • Runs at 2666 MHz PC4-21300 speed for faster application loading
  • Operates at 1.2 V for efficient power use
  • Unbuffered non-ECC design fits standard laptop slots

What this memory is

This is a 16 GB DDR4 SO-DIMM module running at 2666 MHz with a PC4-21300 rating. It operates at 1.2 V using unbuffered, non-ECC 260-pin architecture and is engineered specifically for Dell systems.

Who it suits and who it does not

It fits Dell G3 3579, 3779, G5 15 5587, G7 15 7588, Inspiron 5477 and OptiPlex 3060, 5060, 7060 laptops and desktops. Buyers with non-Dell platforms or systems that require ECC registered memory should look elsewhere.

Behaviour under sustained load

The module is built from OEM-grade components qualified through Dell's certification process. When mixed with existing memory, it operates at the lowest populated speed or the highest speed the system allows, maintaining stability during extended memory-intensive workloads.

Questions about this item

Which Dell laptop models accept this 260-pin SO-DIMM running at 2666 MHz?

This module is qualified for G3 3579, G3 3779, G5 15 5587, G7 15 7588, Inspiron 5477, OptiPlex 3060, 5060 and 7060 systems.

If I keep the original memory in my G5 15 5587, will the new 16 GB stick run at 2666 MHz?

When mixed, the memory operates at the lowest speed populated or the highest speed the system allows, so the 2666 MHz module will down-clock to match the existing stick.

How can I confirm the 16 GB DDR4 module is recognised at the correct speed after installation?

Open Task Manager, go to the Performance tab, select Memory and verify the speed reads 2666 MHz and the total capacity shows the expected increase.
