Dell Inspiron 5593 & 5490 SODIMM

This 8 GB DDR4 2666 MHz SODIMM is built for the Dell Inspiron 15 5593 and Inspiron 24 5000 (5490). It uses a 260-pin layout, runs at 1.2 V and carries CL19 timings. The single-rank module is unbuffered and non-ECC, matching the factory specification for those systems.

Not for ECC or higher-capacity needs

Buyers who want error-correcting code memory should look elsewhere, as this stick is non-ECC. Systems limited to lower speeds will run the module at the slowest installed speed. The platform supports a maximum of 64 GB across two sockets, so this single 8 GB stick leaves room for expansion.

Tool-free slot installation

Insert the module at an angle into the SODIMM slot until the retention clips click. No heat spreader is fitted, so clearance is minimal. Mixing with existing memory is possible but all modules will operate at the slowest timing. A 64-bit operating system is required to address more than 4 GB total.

Questions about this item

Does this 260-pin DDR4 SODIMM fit the two memory slots in a Dell Inspiron 15 5593 or Inspiron 24 5000 (5490)?

Yes, the module matches the 260-pin DDR4 SO-DIMM form factor used by both models, which each provide two sockets supporting up to 64 GB total.

If I keep an existing 2666 MHz CL19 stick and add this 1.2 V unbuffered module, will the system still run at 2666 MHz?

Both modules share the same 2666 MHz speed and CL19 timing, so the memory controller will operate the pair at 2666 MHz without down-clocking.

How can I confirm the new stick is recognised at 2666 MHz and CL19 after installation?

Open Task Manager or a system-information tool and verify the installed memory shows 2666 MHz speed and 19-19-19 timings for the added module.
