Compatibility-Specific DDR3 SO-DIMM Kit

This 8 GB kit contains two 4 GB DDR3 1333 SO-DIMM modules built for Compaq Presario CQ57-439WM and G42-164LA notebooks. The 204-pin form factor matches the factory memory sockets exactly. CAS latency is CL7 with 7-7-7 timings at 1.5 V. Unbuffered, non-ECC operation suits the original platform.

Owners of the Listed Compaq Models

The kit suits anyone restoring or maxing out a CQ57-439WM or G42-164LA to the 8 GB system limit across two slots. Buyers with other laptops, desktops or a different DDR generation cannot use these modules. Systems that require ECC, registered DIMMs or a voltage other than 1.5 V should look elsewhere.

Two-Slot 8 GB Maximum

The Compaq platforms named above support a total of 8 GB across two SO-DIMM sockets. This matched pair fills both slots and reaches that ceiling in one step. Installers must verify their exact model number before ordering.

Questions about this item

Will the 204-pin DDR3 SO-DIMM modules fit the two memory slots in my Compaq Presario Cq57-439Wm?

Yes, the kit matches the notebook’s two 204-pin SO-DIMM sockets and the 8 GB maximum the system accepts.

Can I keep one existing 4 GB stick and add a single 4 GB module from this kit?

The kit is sold as a matched pair; mixing ranks or timings with an unknown module can cause instability, so replacing both sticks is recommended.

How do I verify the CL7 timing and 1333 MHz speed are active after installation?

Open Task Manager’s Performance tab or run CPU-Z; both will show 1333 MHz and the 7-7-7 timing if the modules are running as specified.
