Targeted Notebook Upgrade

This 4GB DDR3 SODIMM is built for HP and Compaq notebooks including the 625, 621, 620, 630, 635, 435 and 431. It suits owners of those models who need a single-module memory increase without guessing compatibility.

Capacity And Speed Limits

The stick provides 4GB at 1333MHz with CL7 7-7-7 timing and runs at 1.5V. It handles everyday multitasking and older 64-bit operating systems, but 4GB will feel tight with many browser tabs or modern office suites.

Build Integration

The 204-pin unbuffered non-ECC module drops into an empty SODIMM slot on the listed notebooks. No heat spreader keeps the profile low for cramped chassis, and the single stick leaves a second slot free for a matching upgrade later.

Questions about this item

Will this 1333 MHz CL7 SODIMM run stably alongside the original 1066 MHz memory in my HP 625?

Yes, the module is rated at 1333 MHz with CL7 timing and will down-clock to match the slower 1066 MHz sticks already installed, operating at the standard 1.5 V DDR3 voltage.

How can I verify the stick is recognised at the correct speed after installation?

Open Task Manager or a tool like CPU-Z; the memory tab should show a single 4 GB 204-pin DDR3 module running at 1333 MHz (PC3-10600) with 7-7-7 latency.

Does the package contain only the memory stick or are any tools or adapters included?

The box contains one 4 GB 204-pin DDR3 SODIMM and nothing else; no screwdriver, adapter or extra cables are supplied.
