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.
