OWC 4GB DDR4 2400MHz SODIMM for HP ProBook

This 4GB DDR4 2400MHz module is built for HP ProBook 430 G5, 430 G6, 440 G5, 440 G6 and 450 G5 laptops. It runs at CL17 latency with a 1.2V operating voltage. The unbuffered non-ECC design matches the factory specifications for these models.

Easy SODIMM installation for listed HP laptops

The 260-pin SODIMM fits the memory slot on the compatible ProBook models without tools in most cases. A mismatch in speed, voltage or pin count will prevent the module from seating or booting. Using a different DDR generation or an ECC module causes compatibility failures.

Check your ProBook model and current memory specs

Verify the exact model number on the service tag matches 430 G5, 430 G6, 440 G5, 440 G6 or 450 G5 before ordering. Confirm the existing RAM is DDR4 2400MHz non-ECC SODIMM to ensure the new module matches. Systems requiring ECC or a different voltage will not work with this part.

Questions about this item

How can I verify the 4GB DDR4 2400MHz module is running at CL17 1.2V after installing it in my HP ProBook 430 G5?

Enter the BIOS or use a tool like CPU-Z to confirm the memory reports 2400 MT/s, CAS latency 17 and 1.2 V operation.

What comes with the OWC 2S4D41R804GB SODIMM and do I need any extra parts for my HP ProBook 440 G6?

The box contains the single 4GB 260-pin DDR4 SODIMM only; no tools, brackets or additional cables are required for installation.

Which capacity should I choose between the 4GB stick and a higher-density option for my HP ProBook 450 G5?

Select the 4GB module if you are replacing one slot or adding to an empty slot; choose a larger capacity only if your model supports more than 4GB per slot and you need the extra total memory.
