OWC 4GB DDR3 SODIMM for HP Presario CQ43

This module is a 4GB DDR3 1333 PC3-10600 CL9 SODIMM built to upgrade HP Presario CQ43 series laptops using DDR3 memory. It runs at 1.5V with a 2Rx8 unbuffered layout and carries JEDEC and ROHS compliance for a warranty-safe installation.

Suits owners of compatible CQ43 models.

The 204-pin form factor fits the HP Presario CQ43 series specified in the compatibility list. Builders working on different laptop families, desktop boards, or systems requiring ECC or registered memory should look at other parts.

Single 4GB CL9 DDR3 1333 module

Capacity, speed and latency are fixed at 4GB, DDR3 1333 (PC3-10600) and CL9. If your CQ43 needs a different capacity, a lower voltage, or a different rank configuration, this module will not match the requirement.

Questions about this item

Should I choose the 4GB SODIMM or a different capacity for my HP Presario CQ43?

The module is a single 4GB DDR3 1333 SODIMM. If your CQ43 has two slots you can add a second identical stick for 8GB total, or replace the existing stick if only one slot is free.

What does the PC3-10600 1333MHz CL9 rating deliver inside the laptop?

It runs at 1333 MT/s with CAS latency 9 at 1.5V, giving the CQ43 the standard DDR3 bandwidth the chipset expects for everyday multitasking and larger file handling.

Will the 204-pin DDR3 SODIMM interface work in my CQ43 without changes?

Yes. The 204-pin unbuffered non-ECC DDR3 SODIMM matches the CQ43 DDR3 slot keying and voltage, so it installs directly with no adapter or BIOS update needed.
