Dell Precision M4400 upgrade

This 8 GB kit contains two 4 GB DDR2 800 SO‑DIMM modules built for the Dell Precision Mobile Workstation M4400. They run at 1.8 V with CL6 6‑6‑6 timing and use unbuffered non‑ECC chips. The 200‑pin form factor matches the factory memory slots exactly.

Not for other laptops

Owners of notebooks that take a different pin count, voltage or DDR generation cannot install these modules. The kit is also unsuitable for desktops, servers or any system that requires ECC or registered memory. Buyers needing more than 8 GB total capacity must look elsewhere.

200‑pin DDR2 SO‑DIMM interface

The decisive specification is the 200‑pin DDR2 SO‑DIMM interface combined with 800 MHz speed and 1.8 V operation; only systems designed for that exact combination will accept the sticks.

Questions about this item

Should I choose the 8 GB kit or a single 4 GB module for my M4400?

The 8 GB kit fills both 200‑pin slots with two 4 GB modules, reaching the workstation's 8 GB maximum; a single 4 GB stick would leave one slot empty and limit total capacity.

What does the PC2‑6400 800 MHz rating deliver in the Precision M4400?

It runs at the platform's native DDR2‑800 speed with CL6 6‑6‑6 timing and 1.8 V, providing the maximum bandwidth the M4400 memory controller supports.

Will this 200‑pin DDR2 SO‑DIMM work in other laptops that take DDR2 memory?

The modules are built to the 200‑pin DDR2 SO‑DIMM standard, but Computer Memory Solutions validates them specifically for the Dell Precision M4400; compatibility with other systems is not guaranteed.
