OWC 4GB DDR4 SODIMM for EliteBook 820 G4 840 G3

This OWC module is a 4GB DDR4 2133MHz SODIMM built for HP EliteBook 820 G4 840 G3 and 850 G3 laptops. It runs at PC4-17000 with CL15 latency and 1.2V operation. The 260-pin non-ECC unbuffered design matches the factory specification for those models.

Not for Systems Outside the Listed EliteBook Range

Buyers who need memory for a different laptop model or a desktop platform cannot use this stick. The part is validated only for the three EliteBook models named above. Systems that require ECC registered modules or a different pin count should look elsewhere.

4GB Capacity Decides the Upgrade Path

The single 4GB capacity determines whether this module fits the target configuration. A slot limited to 4GB or a build that needs exactly one 4GB stick will match this part. Larger capacity requirements mean a different module is necessary.

Questions about this item

Does the 260-pin SODIMM fit the memory slot in an HP EliteBook 840 G3?

Yes, the 260-pin DDR4 SODIMM matches the slot used by the EliteBook 840 G3, 850 G3 and 820 G4 models.

What is the first step when installing this module, and where do people go wrong?

Power off the laptop, remove the battery if accessible, then press the module firmly into the slot until both side clips click; the common mistake is stopping before the clips engage.

Will the 4GB CL15 module need any firmware updates or replacement parts during its service life?

No firmware is required; the JEDEC-compliant DDR4 module has no moving parts and is covered by a limited lifetime warranty, so no scheduled replacement is needed.
