OWC 4GB DDR4 2400 SODIMM for HP ProBook

This 4GB DDR4 2400MHz CL17 module is built for specific HP ProBook laptops. It runs at 1.2V as a 260-pin non-ECC unbuffered SODIMM with a 1Rx8 rank configuration and no heat spreader. OWC tests every unit in-house to meet JEDEC and RoHS standards for a warranty-safe upgrade.

Suits owners of listed ProBook models needing

Buyers whose laptop is not an HP ProBook 445R G6, 455 G6, 455R G6, 640 G3 or 650 G3 should look elsewhere. Systems requiring ECC registered memory or a different DDR generation will not accept this module. It is a single 4GB DIMM, so configurations needing higher capacity per slot or matched pairs must consider other options.

Check your ProBook model number

Verify the exact model name matches the supported list before ordering. Confirm the laptop has an available 260-pin DDR4 SODIMM slot and that the BIOS recognises 2400MHz CL17 1.2V unbuffered memory. OWC recommends using identical capacity, speed and manufacturer modules for optimal performance.

Questions sur cet article

What laptop slot does the 260-pin SODIMM fit into?

The module plugs into any standard DDR4 260-pin SO-DIMM slot found in the HP ProBook 445R G6, 455 G6, 455R G6, 640 G3 or 650 G3.

Can I mix this CL17 2400 MHz stick with slower DDR4 already in my ProBook?

Yes, the system will run all installed modules at the speed of the slowest stick, so existing slower DDR4 will still work alongside this module.

How do I confirm the 4 GB module is recognised at 2400 MHz after installation?

Open Task Manager or BIOS and verify the installed memory shows 4 GB running at 2400 MHz with CL17 timings.
