OWC 2GB DDR3 1600 SODIMM

This 2GB DDR3 1600 SODIMM from OWC upgrades compatible HP Presario CQ42 notebooks. It runs at PC3-12800 speed with CL11 latency and operates at the standard 1.5V. The unbuffered, non-ECC module uses a 1Rx8 configuration on a 204-pin form factor.

Suitable for listed HP Presario models

The module is validated for the HP Presario CQ42-303LA, CQ42-320CA and CQ42-324LA. It is not for systems that require a different DDR generation, ECC capability, registered buffering, or a voltage other than 1.5V. Buyers needing higher capacity per slot or a different pin count should look elsewhere.

2GB capacity per module

This single SODIMM provides exactly 2GB of memory. The capacity determines whether the module meets the target system's maximum supported memory per slot and total system limit.

Questions about this item

Does the 2GB DDR3 1600 SODIMM arrive alone or with any tools or cables?

The package contains a single 2GB DDR3 1600 CL11 1Rx8 204-pin 1.5V Non-ECC SODIMM module only; no tools, cables or additional components are included.

I see one 2GB 204-pin DDR3 1600 CL11 module listed — are there other capacities or speeds for this HP Presario CQ42 series?

This listing offers the 2GB PC3-12800 CL11 1.5V SODIMM; other capacities or speeds are not shown for the CQ42-303LA, CQ42-320CA and CQ42-324LA models.

Will the 1600MHz PC3-12800 rating actually run at 1600MHz inside my HP Presario CQ42-324LA?

The module is rated DDR3 1600 PC3-12800 CL11 1.5V; the laptop's memory controller determines the final operating speed, which may be lower than the rated 1600MHz.
