16 GB DDR4 SODIMM for HP ProBook

This 16 GB DDR4 SODIMM runs at 3200 MHz with CL22 latency and 1.2 V operation. It is built to JEDEC PC4-25600 specifications and uses a 260-pin unbuffered non-ECC design. The module targets HP ProBook 455 G9 and 635 Aero G7 notebooks that accept standard laptop memory upgrades.

Suits owners of listed ProBook models needing more

Buyers whose laptops are not the HP ProBook 455 G9 or 635 Aero G7 should look elsewhere because this module is validated only for those systems. Users who require ECC error correction or registered memory must choose a different product since this stick is non-ECC and unbuffered.

Verify your laptop model and free SODIMM slot

Check that your device is exactly an HP ProBook 455 G9 or 635 Aero G7 before ordering. Confirm the machine has an available 260-pin DDR4 SODIMM socket and that the BIOS supports 3200 MHz PC4-25600 memory at 1.2 V. Matching capacity and speed across all installed modules is recommended for best stability.

Questions about this item

What laptop models must I own for this 260-pin DDR4 SODIMM to be compatible?

This module is validated for the HP ProBook 455 G9 and the HP ProBook 635 Aero G7. Both systems accept 260-pin DDR4 Non-ECC SODIMMs at 1.2V.

How will this CL22 3200MHz module behave if I keep an existing DDR4 stick in the second slot?

The system will run both modules at the lowest common speed and highest shared latency. Matching capacity, speed and manufacturer is recommended for optimal performance.

How can I verify the 16GB module is running at 3200MHz CL22 after installation?

Open Task Manager or a hardware monitor and confirm the memory shows 3200 MT/s with CAS latency 22. The BIOS memory info screen will also list PC4-25600 timing.
