2GB DDR2 SO-DIMM for Compaq Presario

This 200-pin DDR2 SODIMM delivers 2GB at 800MHz with CL6 timing. It operates at 1.8V and uses unbuffered, non-ECC chips in a 2Rx8 configuration. The module is built with major-brand components and carries a limited lifetime warranty from Computer Memory Solutions.

Owners of CQ61-100EE, CQ61-100ES or CQ61-100EW

The stick is validated for those three Presario models where the system maximum is 8GB across two sockets. Builders working on any other laptop or desktop platform should look elsewhere, as the pin layout, voltage and signalling are specific to DDR2 SO-DIMM slots.

DDR2 800MHz (PC2-6400) speed grade

The module runs at the 800MHz data rate designated PC2-6400. If the target machine requires a different DDR2 speed, a lower CAS latency, ECC support or a 1.5V operating voltage, this part will not meet that requirement.

Questions about this item

Will the 200-pin DDR2 SODIMM fit the memory slots of my Compaq Presario CQ61-100EE?

Yes, this module uses the 200-pin DDR2 SO-DIMM form factor specified for the CQ61-100EE, CQ61-100ES and CQ61-100EW models.

If I keep an existing DDR2 module in the second slot, will this stick run at 800 MHz?

The system will clock both modules to the lowest common speed; if the other module is slower, this stick will down-clock to match it.

How can I confirm the new RAM is detected at 800 MHz after installation?

Check the BIOS memory information or use a tool such as CPU-Z to verify the module reports DDR2-800 (PC2-6400) with CL6 timings.
