Dell Inspiron 15 memory upgrade

This 4GB DDR4 SODIMM is built for the Dell Inspiron 15 3565, 3567, 5568, 5578 and 7566. It installs in a 260-pin slot and runs at 2133MHz with CL15 latency. The module uses 1.2V power and follows JEDEC PC4-17000 specifications.

Users adding a single stick to a free slot

This suits owners who have an empty SODIMM socket and want a straightforward capacity increase. It will not help systems that already run two matched modules in dual-channel mode, nor machines that require ECC or registered memory. Buyers needing more than 4GB per slot should look elsewhere.

The deciding spec is 4GB capacity at DDR4-2133

If your laptop accepts a 260-pin DDR4 SODIMM at this speed and voltage, the module will work. The 4GB limit per stick is the figure that determines whether this part fits your upgrade plan.

Questions about this item

How do I verify the 2133 MHz CL15 DDR4 module is running correctly after installing it in my Inspiron 15 5568?

Enter the BIOS or use a system-information tool such as CPU-Z to confirm the memory reports 2133 MHz, CL15 timings and 1.2 V operation.

What comes in the box with the 4 GB SODIMM and what else must I purchase separately?

The package contains only the 4 GB 260-pin DDR4 SODIMM; no tools, screws or additional modules are included.

Which capacity should I choose between the 4 GB stick and higher-capacity kits for my Inspiron 15 7566?

This listing is for a single 4 GB module; if your laptop has two slots and supports more total memory, adding a second identical stick will give you 8 GB in dual-channel mode.
