A-Tech 4GB DDR2 667MHz SODIMM

This A-Tech module adds 4GB of DDR2 memory to compatible laptops, notebooks and all-in-one systems. It uses the 200-pin SO-DIMM form factor and runs at 667MHz with CL5 latency. The stick is non-ECC, unbuffered and operates at the standard 1.8V. It suits owners of older DDR2 platforms who want a straightforward capacity increase.

Capacity and headroom for DDR2 platforms

A single 4GB stick fills one slot and raises the total memory available for everyday applications and multitasking. Performance scales with the DDR2 667MHz bus, so workloads that fit within this bandwidth see snappier response. Systems limited to lower densities or fewer slots will hit a ceiling here; the module cannot exceed the platform's maximum supported memory per slot or total capacity.

Thermals noise and power draw in normal use

Standard 1.8V DDR2 SO-DIMMs draw modest power and run passively without a fan. The module produces no audible noise and adds minimal heat inside the chassis. Typical operation stays within the thermal envelope of the laptop's existing cooling design.

Questions about this item

Will this 667 MHz DDR2 module work in a laptop that currently has slower DDR2 installed?

The module runs at 667 MHz and uses the standard 1.8 V DDR2 voltage; it will operate at the speed supported by your laptop's memory controller.

How can I confirm the module is recognised at the correct speed after installation?

Check the BIOS memory information or a system utility such as CPU-Z to verify the module reports 667 MHz (PC2-5300) and CL5 timings.

Does the package include anything besides the 4 GB 200-pin SO-DIMM?

Only the single 4 GB DDR2 667 MHz SO-DIMM is supplied; no additional cables, brackets or tools are included.
