HP 430 620 625 630 635 memory upgrade

This OWC module adds 4GB of DDR3 1066 PC3-8500 memory to compatible HP laptops. The 204-pin SODIMM runs at 1.5V with CL7 latency and a 2Rx8 organisation. It is an unbuffered non-ECC part built to JEDEC and ROHS specifications.

Owners of listed HP models needing more RAM

The upgrade suits HP 430, 620, 625, 630 and 635 notebooks that accept a single 4GB DDR3 SODIMM. Builders working on desktops, servers or any system requiring ECC, registered modules or a different pin count should look elsewhere.

204-pin DDR3 SODIMM form factor

The physical 204-pin layout and DDR3 signalling determine whether the module fits the target slot. Only systems designed for this exact form factor and voltage will accept it.

Questions about this item

How can I verify the 4GB DDR3 1066 CL7 SODIMM is recognised correctly after installing it in my HP 630?

Open Task Manager or System Information in Windows and confirm the installed memory shows 4GB at 1066 MHz with CL7 timings; the BIOS POST screen will also list the module speed and capacity.

What comes with the OWC 8S5D32R804GB module and do I need any extra parts for my HP 625?

The package contains only the single 204-pin 1.5V Non-ECC SODIMM; no tools, brackets or additional cables are required for installation in the HP 625.

Which capacity should I choose if my HP 430 currently has one empty SODIMM slot?

This listing is a single 4GB DDR3 1066 module; add it to the empty slot to bring total memory to 4GB or pair it with an identical 4GB stick for 8GB dual-channel operation.
