4GB DDR2 Desktop Memory Upgrade

This 4GB DDR2 module adds capacity to desktops that use PC2-6400 memory. It is intended for owners of older systems who need more RAM for everyday tasks. The low-density design helps compatibility with a wider range of motherboards. Condition is new from a supplier with 25 years of component experience.

Replacing Smaller DDR2 Modules

The upgrade makes sense when a system has free slots but less than 4GB installed. Moving from 1GB or 2GB to this module can reduce swapping and improve responsiveness. The jump is worth it if the board accepts low-density 4GB sticks and the operating system can address the extra memory. No other memory types or generations are addressed by this part.

Simple DIMM Installation

Installation requires opening the case and seating the DIMM firmly until the retention clips click. The most common issue is a motherboard that only supports high-density chips or lower capacities per slot. Mixing densities or speeds can also prevent the system from posting. Verify the board manual for supported configurations before fitting.

Questions about this item

Will the 240-pin DDR2 DIMM fit a standard desktop motherboard slot?

Yes — the module uses the standard 240-pin DDR2 form factor used by desktop boards that accept PC2-6400 memory.

What is the common installation mistake with low-density DDR2 modules?

Builders often leave the retention clips unlatched; press firmly until both clips click to seat the 4 GB stick at 800 MHz.

When might the 4 GB DDR2 stick need replacement?

Replace it if memory diagnostics report errors or if the system becomes unstable after 25 years of continuous service.
