4GB DDR4 2133MHz SODIMM for HP

This 4GB DDR4 2133MHz CL15 SODIMM is a direct replacement for HP part numbers 854977-800 and 865980-001. It runs at 1.2V with a 260-pin unbuffered non-ECC layout. The module targets owners of compatible HP laptops, notebooks and all-in-one PCs who need a straightforward capacity upgrade.

Who this suits and who it does not

Buyers looking to replace a failed stick or add a single 4GB module to a supported HP system will find the correct fit here. It is not for systems that require ECC or registered memory, nor for builds needing higher capacity per slot, faster speeds or lower latency than CL15. Builders assembling desktop PCs should look elsewhere because this is a SO-DIMM form factor.

The specification that decides compatibility

The decisive figure is the 260-pin DDR4 SO-DIMM interface combined with 2133MHz CL15 timing at 1.2V. Your laptop must accept non-ECC unbuffered DDR4 SO-DIMMs at this exact speed and voltage for the module to work. Verify the HP part numbers 854977-800 or 865980-001 against your service manual before ordering.
