OWC 4GB DDR3 1600 SODIMM

This 4GB DDR3 SODIMM runs at 1600MHz with CL11 latency and 1.5V operation. It uses a 204-pin unbuffered non-ECC design in a 2Rx8 configuration. The module is built to JEDEC standards for direct replacement in compatible notebooks.

For HP Presario CQ42 notebook upgrades

This module suits owners of HP Presario CQ42-303LA, CQ42-320CA or CQ42-324LA models needing a single 4GB stick. Builders requiring ECC, registered DIMMs, higher capacities per slot, or different pin counts should look elsewhere.

Single 4GB capacity for everyday loads

The 4GB capacity handles web browsing, office applications and light multitasking comfortably. Systems needing more memory for virtual machines, heavy creative suites or large datasets will run out of headroom with this module alone.

Questions about this item

Will this 204-pin SODIMM fit the memory slot in my HP Presario CQ42-303LA?

The module is a 204-pin DDR3 SODIMM built to JEDEC standards, matching the slot and electrical spec for the listed Presario models.

Can I pair this 2Rx8 CL11 stick with the original memory already in my laptop?

Mixing ranks and timings may work but is not guaranteed; for best stability use identical modules or run this stick alone.

How do I confirm the module runs at 1600 MHz with CL11 timing after installation?

Open Task Manager or CPU-Z and check the memory tab — it should show 1600 MHz speed and CL11 latency when the system boots correctly.
