Target System Upgrade

This 2 GB DDR2 module is built for the eMachines ET1331-40E, ET1331-45, ET1331G-03W and ET1331G-05W. It delivers a single 240-pin DIMM rated at 800 MHz with CL6 timings. The unbuffered, non-ECC design matches the original specification for these desktop systems.

Slot And Limit Check

Verify that your motherboard has a free 240-pin DDR2 slot and that the total installed memory will not exceed the 4 GB maximum supported by these models. The board provides four sockets, so population order may matter. Ensure the BIOS is current enough to recognise a 2Rx8 density module at 1.8 V.

Steady State Operation

Running at the standard 1.8 V without a heat spreader, the stick relies on case airflow to maintain temperature during extended workloads. The Major Brand Chipset components are specified for continuous operation at the rated 6-6-6 timing. No overclocking headroom is implied or guaranteed.

Questions about this item

Does the box contain anything besides the single 2GB DDR2 800MHz DIMM, or do I need to buy extra modules separately?

The package includes one 2GB 240-pin DDR2-800 module and nothing else; additional sticks must be purchased separately if you want more capacity.

The listing mentions several eMachines ET1331 models — which ones are confirmed for this 2GB stick?

Compatibility is guaranteed for the ET1331-40E, ET1331-45, ET1331G-03W and ET1331G-05W systems.

What does the PC2-6400 800MHz rating actually deliver once the module is installed in a compatible machine?

The module runs at 800MHz with CL6 timing at 1.8V, providing 2GB of non-ECC unbuffered memory for the supported eMachines desktops.
