Dell Optiplex 330 DDR2 upgrade

This 4 GB kit contains two 2 GB DDR2-800 DIMMs built for the Dell Optiplex 330 desktop. The modules are unbuffered non-ECC memory rated at CL6 timing and 1.8 V operation. They install directly into the system's 240-pin slots to raise total memory to the supported maximum.

Check your Optiplex 330 configuration

Verify the desktop has two free 240-pin DDR2 sockets before ordering. The board accepts a maximum of 4 GB across both slots, so existing modules must be removed if they are already populated. Confirm the BIOS is updated to recognise the full capacity and that the installed CPU supports DDR2-800 speed.

Two-stick kit completes the memory array

The paired DIMMs fill both sockets for dual-channel bandwidth without mixing densities. No heat spreader is fitted, keeping the profile low for the Optiplex 330 chassis. The 1.8 V rating matches the platform's standard voltage, so no manual voltage adjustment is required. The kit frees you from hunting single sticks of different capacities.

Questions about this item

What is included in the box and does anything else need to be purchased?

The box contains two 2 GB DDR2-800 DIMM modules, a 2-piece kit that fills both sockets of the OptiPlex 330. No additional parts are required for installation.

Which capacity should I choose for this system?

The OptiPlex 330 supports a maximum of 4 GB across its two sockets, so the 4 GB kit (2 × 2 GB) is the correct choice to reach that limit.

What does the 800 MHz rating mean once the memory is installed?

The modules run at 800 MHz with CL6 timing and 1.8 V, delivering PC2-6400 bandwidth for the OptiPlex 330's memory controller.
