Compatible Dell Dimension upgrade

This 1 GB kit contains two 512 MB DDR1-2100 modules designed for Dell Dimension 2300C, 2350, 2400, 4400, 4550, 4500 and 4500s desktops. It suits owners restoring or maintaining those specific systems.

Simple 184-pin DIMM installation

Each module fits a standard 184-pin DDR slot; alignment notches prevent reversed insertion. The only common issue is mixing these 266 MHz sticks with faster DDR modules, which forces the bus to the slowest speed.

1 GB total capacity for legacy workloads

The paired 512 MB modules provide the maximum memory many of the listed Dimension models officially recognise. Systems requiring more than 1 GB or a different memory type will not benefit from this kit.
