OWC 8GB DDR4 3200 SODIMM for HP ProBook

This OWC module provides 8GB of DDR4 memory rated at 3200MHz with CL22 latency. It is built as a 260-pin non-ECC SODIMM operating at 1.2V for compatible HP ProBook laptops. The single-rank design meets JEDEC standards for a straightforward capacity increase.

Verify your ProBook model

Confirm the laptop is an HP ProBook 455 G9 or 635 Aero G7 to match the validated compatibility list. Check how many SODIMM slots the chassis offers and whether a module is already installed in each one. The upgrade requires a free 260-pin DDR4 slot and cannot be used in systems that demand ECC or registered memory.

Sustained workloads benefit from stable JEDEC

The memory runs at standard 1.2V without overclocking, so thermals remain predictable during long sessions. CL22 timings deliver consistent latency for multitasking and large-file handling over extended periods. OWC testing at their in-house lab ensures each stick maintains rated speed without throttling under continuous load.

Questions about this item

What comes in the box with this OWC SODIMM and is anything else required?

The package contains the single 8 GB DDR4 3200 CL22 1.2 V 260-pin SODIMM module; no additional parts or tools are needed for installation.

My ProBook 455 G9 has two slots — should I add a second 8 GB stick or replace the existing one?

OWC recommends matching capacity, speed and manufacturer for optimal performance, so adding an identical 8 GB module is the preferred route if a slot is free.

Will the CL22 latency at 3200 MHz actually improve everyday responsiveness on my 635 Aero G7?

Upgrading to this JEDEC-standard 3200 MHz module increases bandwidth over slower factory memory, giving snappier multitasking and faster large-file handling.
