System-specific 4 GB DDR4 SODIMM

This 4 GB DDR4 module is built for Dell Inspiron 15 models 5565, 5566, 5567, 5568 and 7569. It uses a 260-pin SO-DIMM form factor and runs at 2133 MHz with CL15 latency. The kit suits owners of those laptops who need a straightforward capacity increase.

Low-voltage operation keeps thermals modest

At 1.2 V the module draws minimal power and generates little heat inside a compact chassis. No heat spreader is fitted, so airflow from the laptop’s existing fan handles cooling. The JEDEC-standard design avoids extra noise or thermal load during everyday workloads.

Fits the listed Dell slots without extra parts

The unbuffered, non-ECC stick installs directly into the factory memory slot on compatible Inspiron 15 units. It requires no BIOS update, adapter or proprietary tool. Builders who need ECC, registered memory or capacities beyond 4 GB per module should look elsewhere.

Questions about this item

How do I install the 260-pin SODIMM in my Dell Inspiron 15 5567?

Power off the laptop and remove the battery if possible. Open the memory access panel, align the notch on the module with the slot key, insert the module at an angle, then press down until the retention clips click into place.

What maintenance or replacement will this 4GB DDR4 module need later?

No routine maintenance is required for this non-ECC, unbuffered memory. If a memory error appears, run the Dell built-in diagnostics to confirm a module fault, then replace the stick.

What limit appears first when the 2133MHz CL15 RAM runs under sustained load?

The CL15 latency at 1.2V is the first constraint; sustained heavy workloads will hit timing and voltage limits before thermal throttling, since the module has no heat spreader.
