2GB DDR2 SODIMM for Compaq Presario

This 2GB DDR2-667 SO-DIMM is built for Compaq Presario CQ56 models including the 160Ep, 160Sv and 180Ep. It uses a 200-pin unbuffered design with CL5 timing at 1.8V. The module suits owners restoring or upgrading these specific legacy notebooks.

Straightforward notebook installation

Installation follows the standard SODIMM procedure: power off, remove the battery, open the memory door and press the stick into the slot until the clips latch. The 200-pin keying prevents mis-insertion. The only common issue is exceeding the two-slot, 8GB maximum supported by the CQ56 platform.

2GB single module capacity

One 2GB stick adds usable memory for everyday tasks on these machines. Two such modules fill both slots and reach the 8GB ceiling reported for the series. A single module leaves one slot open for future expansion, while a third stick cannot be used because the platform provides only two sockets.

Questions about this item

How can I verify the 2GB DDR2-667 SODIMM is running at the correct 667 MHz speed after installation?

Open the BIOS or a system information tool such as CPU-Z and confirm the memory frequency reads 667 MHz with timings of 5-5-5 at 1.8 V.

What is included in the package and do I need any extra parts for my Compaq Presario CQ56?

The box contains one 2 GB 200-pin DDR2 SO-DIMM module; no additional components are required for installation.

Which capacity should I choose if my CQ56-140SI has two slots and supports up to 8 GB?

Each slot accepts a 2 GB module, so installing two of these kits will reach the 8 GB maximum.
