HP-Compatible DDR4 SODIMM

This 8GB DDR4 2133MHz CL15 module is a direct replacement for HP part numbers 865963-001, 865964-001 and 854978-800. It uses the standard 260-pin SO-DIMM form factor and runs at 1.20V. The unbuffered, non-ECC design suits mainstream laptop and all-in-one memory slots.

Suits HP service parts; not for ECC or higher speeds

Buyers repairing or upgrading compatible HP laptops and all-in-ones with these exact service part numbers will find a matched specification. Systems requiring registered or ECC memory cannot use this unbuffered module. Laptops limited to lower DDR4 speeds or different pin counts should verify compatibility before purchasing.

2133MHz DDR4 speed rating

The module operates at DDR4 2133 (PC4-17000) with a CAS latency of 15. This speed grade determines whether the memory matches the system's supported transfer rate. Installing a module of a different speed grade may prevent boot or force the system to run at a lower frequency.
