4GB DDR4 2133MHz SODIMM for HP ProBook

This OWC module adds 4GB of DDR4 memory at 2133MHz with CL15 timing. It uses a 260-pin SODIMM form factor and runs at 1.2V. The part is designed for specific HP ProBook models including the 430 G4, 470 G4, 640 G2, 650 G2 and 655 G3.

Suits owners of listed ProBooks needing a single

Buyers whose laptop is not in the compatibility list should verify before purchase. Systems requiring ECC or registered memory cannot use this non-ECC unbuffered module. Users needing higher capacity per slot or faster speeds must select a different part.

260-pin DDR4 SODIMM form factor decides fit

The module matches the physical slot and electrical specification of the supported ProBooks. A different pin count or memory generation will not install or function in these machines.

Questions about this item

Will the 260-pin SODIMM fit the memory slot on my HP ProBook 430 G4?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor that matches the slot in the listed ProBook models.

What is the correct way to seat the module so it locks in place?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click — many people stop before the clips engage.

When should I consider replacing this 4GB stick?

Replace it if memory diagnostics report errors, if the system becomes unstable under load, or when you upgrade to a higher-capacity kit.
