Dell Dimension 4400 memory kit

This 2 GB kit contains two 1 GB unbuffered DDR1 DIMMs rated at DDR266 (PC 2100) with CL2.5 timing. It is built specifically for Dell Dimension 4400 desktops that require 184-pin non-ECC memory running at 2.5 V.

Check your current configuration

The system has two memory sockets and a maximum supported capacity of 2 GB. Verify how many slots are already populated and whether the installed modules are 512 MB or 1 GB so you can reach the 2 GB limit without exceeding the socket count.

Thermals and power in normal use

These modules operate at the standard DDR1 voltage of 2.5 V and have no heat spreader, so they rely on case airflow for cooling. Power draw is low and the sticks run silently because they contain no moving parts.

Questions about this item

Does the A109 kit include both memory modules or do I need to buy a second 1GB stick separately?

The kit ships as a matched pair of two 1GB 184-pin DDR266 DIMMs so the full 2GB upgrade is ready to install.

My Dimension 4400 manual only mentions 512MB modules — will this 1GB per slot kit actually work?

The A109 kit is validated for the Dimension 4400 and uses 1GB 2Rx8 modules that let the system reach its 2GB maximum.

What does the PC2100 266MHz rating mean for everyday performance in this desktop?

It sets the memory bus at 266MHz with CL2.5 timing giving the Dimension 4400 its rated bandwidth for office applications and legacy operating systems.
