Compatible HP Laptop Upgrade

This OWC SODIMM is built for HP 430, 620, 625, 630 and 635 notebooks. It delivers 2GB of DDR3 memory at 1066MHz with CL7 latency. The module follows the PC3-8500 standard and runs at 1.5V without ECC or buffering. Installation is a straightforward DIY task on supported models.

Buyers Needing Higher Capacity Should Look Elsewhere

The single 2GB stick suits a basic refresh or a slot-filling upgrade on the listed HP machines. It will not help users who need more than 2GB per slot or who require dual-rank density for specific chipset configurations. Systems outside the five named models are not guaranteed to work with this part.

1066MHz DDR3 Speed Decides Fit

The module operates at DDR3 1066 (PC3-8500) with CL7 timing. This exact speed grade must match the memory controller specification of the target HP laptop. If the system requires a different DDR3 frequency or latency, the upgrade will not function correctly.

Questions about this item

What DDR3 speed does the PC3-8500 rating deliver in practice?

The module runs at 1066MHz with CL7 latency under the JEDEC-standard PC3-8500 specification.

Which physical slot does the 204-pin SODIMM require in the HP 430, 620, 625, 630 or 635?

It fits the standard DDR3 SO-DIMM socket used in those HP laptop and mini-PC models.

How is the module installed and what step do people often miss?

Power off, remove battery if accessible, insert the SODIMM at an angle until the gold contacts disappear, then press down until the side clips click — many forget to seat both clips fully.
