Questions about this item

Does my HP Presario CQ43 need an empty 204-pin SODIMM slot to install this 2GB DDR3 1333 module?

Yes, the module requires one free 204-pin DDR3 SODIMM slot in the CQ43. The laptop must support DDR3 memory at 1.5V and accept non-ECC, unbuffered 1Rx8 modules.

Can I keep an existing PC3-10600 CL9 stick in the other slot and add this OWC module alongside it?

Yes, this module matches the DDR3 1333 PC3-10600 CL9 1.5V specification. Pairing it with an identical stick will run in dual-channel mode if the CQ43 supports it.

After fitting the module, how do I confirm the CQ43 recognises the full 2GB at 1333 MHz?

Open Task Manager or System Information in Windows and verify the installed memory shows 2GB running at 1333 MHz. The BIOS memory summary on boot will also list the correct speed and capacity.
