Capacity and interface

This is a 1GB DDR2 desktop memory module that runs at 533MHz with a PC2-4200 rating. It uses a 240-pin unbuffered DIMM form factor and operates at the standard 1.8V for DDR2.

Who this suits and who should look elsewhere

It suits owners of older desktop PCs that require DDR2 533MHz non-ECC memory and have a free 240-pin slot. Systems that need ECC, registered modules, or a different DDR generation will not accept this part.

Deciding specification

The module is DDR2 533MHz PC2-4200 unbuffered non-ECC at 1.8V; if your motherboard specifies a different speed, voltage, or memory type this module will not be compatible.
