8GB DDR2 SODIMM kit for Compaq Presario CQ56

This kit provides two 4 GB modules totalling 8 GB of DDR2 800 memory. It is built for the Compaq Presario CQ56 series notebooks listed in the compatibility data. The 200-pin SO-DIMM form factor matches the two memory slots in those laptops. Installation restores the factory maximum memory configuration.

Suits owners of listed CQ56 models needing

Buyers with a compatible CQ56 notebook can reach the 8 GB ceiling supported by the platform. The unbuffered, non-ECC design matches the original specification. It does not suit laptops that use a different pin count or voltage, or systems that require error-correcting or registered modules.

200-pin DDR2 800 (PC2 6400) interface

The modules run at 800 MHz with CL6 6-6-6 timing at 1.8 V. This exact speed, pin layout and voltage are required for the CQ56 series. A mismatch in any of those parameters will prevent the memory from functioning.

Questions about this item

Does the 8GB (2x4GB) DDR2 800MHz kit include both SODIMM modules or must I buy the second stick separately?

The package contains two 4GB 200-pin DDR2 SODIMM modules, so the full 8GB upgrade is supplied in one box.

My CQ56-219WM has two slots — should I choose this 2x4GB kit or a single 8GB module?

The CQ56 series uses two slots with an 8GB maximum, so the matched 2x4GB kit fills both sockets and reaches the limit.

Will the CL6 1.8V timing of these PC2-6400 sticks run at 800MHz once installed in a Presario CQ56?

The modules are rated DDR2-800 CL6 at 1.8V and the notebook's memory controller operates at that speed, so they will run at 800MHz.
