HP Presario CQ50 memory upgrade

This 2GB DDR2 SODIMM is built for HP and Compaq Presario CQ50 notebooks. It runs at 800MHz with CL6 timing and 1.8V voltage. The module uses a 200-pin unbuffered, non-ECC design and carries a major brand chipset. It replaces OEM part numbers such as 451400-001 and 482169-001.

Who this suits and who should look elsewhere

The stick fits CQ50 models including CQ50-100, CQ50-101AU, CQ50-102LA and CQ50-103ER. It is intended for owners upgrading a compatible notebook to the supported memory limit. Buyers whose laptop requires ECC or registered modules, or who need a different pin count, voltage or speed, cannot use this part.

Deciding specification

The memory operates at DDR2 800 (PC2 6400) with CL6 6-6-6 timing. This speed and latency combination determines whether the module matches the notebook's memory controller requirements. Confirm the system specifies PC2 6400 before ordering.

Domande su questo articolo

Does my Presario CQ50 need a free 200-pin DDR2 SODIMM slot to install this 2 GB module?

Yes, the notebook has two SODIMM sockets; one must be vacant for this 200-pin stick to fit.

Will this PC2-6400 800 MHz stick run at its rated speed if the other slot holds slower DDR2 memory?

The memory controller will drop both modules to the lowest common speed, so the new stick will match the slower module.

How can I confirm the 2 GB upgrade is recognised after fitting the CM256646400SO?

Check the BIOS memory summary or Windows Task Manager — both should show the total capacity increased by 2 GB.
