2GB DDR2 SODIMM for legacy laptops

This 200-pin DDR2 module delivers 2GB at 533 MHz with CL4 latency and 1.8V operation. It targets owners of older notebooks and all-in-one systems that require PC2-4200 non-ECC unbuffered memory for a straightforward capacity upgrade.

Steady throughput on older platforms

The CL4 timing and standard 1.8V voltage provide consistent bandwidth during extended multitasking sessions without the voltage scaling seen in later DDR generations. Sustained workloads such as background updates or multiple browser tabs remain stable because the module operates within its rated JEDEC specification.

Low heat and silent operation

With no heatsink or active cooling required, the module adds negligible thermal load to the laptop chassis. Power draw stays at the DDR2 standard 1.8V level, so battery runtime and fan behaviour are unaffected in typical daily use.

Questions about this item

How much heat and power does this 1.8V DDR2 533 MHz module draw during all-day use?

It runs at the standard DDR2 voltage of 1.8V with no ECC or registered circuitry, so heat and power draw stay at typical laptop SODIMM levels for continuous operation.

What must my laptop already have for this 200-pin DDR2 SODIMM to work?

A free 200-pin DDR2 SO-DIMM slot that accepts PC2-4200 unbuffered non-ECC memory at 1.8V.

Will this PC2-4200 CL4 stick run reliably next to an existing PC2-4200 module?

Yes, matching speed (533 MHz), voltage (1.8V), latency (CL4), and unbuffered non-ECC design lets it operate in dual-channel if the platform supports it.
