System-specific DDR2 SO-DIMM kit

This 4 GB kit contains two 2 GB modules built to the DDR2-667 (PC2-5300) standard. It is designed as a direct upgrade for the Dell Inspiron 15 1525 notebook. The modules use a 200-pin SO-DIMM form factor and operate at 1.8 V. They are unbuffered, non-ECC memory with CL5 5-5-5 timing.

Capacity and headroom for DDR2 systems

The paired modules fill both memory sockets of the compatible notebook, reaching the platform's 4 GB maximum. This configuration suits everyday office applications and light multitasking on legacy hardware. It will not meet the needs of modern operating systems, 64-bit workloads, or users who require more than 4 GB of system memory.

Two-module kit simplifies installation

The matched pair enables dual-channel operation where the platform supports it, delivering the full bandwidth available to the chipset. No heat spreaders are included, keeping the modules low-profile for tight notebook chassis. The package supplies only the two SO-DIMM sticks; no software, tools or additional accessories are bundled.

Questions about this item

Will the 200-pin DDR2 667MHz SODIMM kit work in a Dell Inspiron 15 1525 that currently has one 2GB module installed?

Yes, the kit is built for the Inspiron 15 1525 and matches its DDR2 667 (PC2-5300) specification; adding the two 2GB sticks fills both slots for the 4GB maximum.

How can I confirm the new RAM is running at the rated 667MHz CL5 timing after installation?

Open Task Manager or CPU-Z; the memory tab should show 667MHz speed and 5-5-5-15 timings at 1.8V.

Does the package include anything besides the two 2GB SODIMM sticks, or do I need a screwdriver and anti-static strap separately?

The box contains only the two memory modules; a small Phillips screwdriver and an anti-static wrist strap are not included.
