1GB DDR2 desktop memory module

This 1GB DDR2 module plugs into a standard 240-pin DIMM slot on a desktop motherboard. It is suited for systems that require a single stick of dual-rank memory running at 1.8V.

Upgrade path for legacy DDR2 platforms

The module replaces an empty slot or a lower-capacity stick in a board that accepts DDR2 memory. The jump is worthwhile when the existing configuration cannot hold the operating system and active applications together.

Build integration with 1.8V DDR2 boards

The stick needs a motherboard with 240-pin DDR2 slots and a memory controller that supports 128M x 72 organisation at 1.8V. It frees one slot for additional modules while keeping the voltage requirement consistent across the array.

Questions about this item

Will the 240-pin DIMM fit my motherboard slots?

The module uses the standard 240-pin DIMM form factor for DDR2 desktop memory. Check that your board has DDR2 DIMM slots and supports 1.8V operation before installing.

How do I install the 1GB DDR2 module correctly?

Power off the PC, open the case, align the notch on the module with the slot key, press firmly until both retention clips click. The step often missed is verifying the clips fully lock on both ends.

Does the 128M x 72 dual-rank module need any future maintenance?

No routine maintenance is required for this DDR2 DIMM. If errors appear later, run a memory diagnostic and reseat the module; replacement is only needed if the module itself fails.
