OWC 4GB DDR4 2133MHz CL15 1.2V 260pin SODIMM 2S1D41R804GB memory upgrade

HP Pavilion 14-al memory upgrade

This 4GB DDR4 SODIMM is built for the HP Pavilion 14-al003ng, 14-al003ni, 14-al004ng, 14-al004ni and 14-al005la notebooks. It runs at 2133MHz with CL15 latency at the standard 1.2V. The unbuffered, non-ECC module uses a 1Rx8 rank layout and has no heat spreader. It is a straightforward drop-in part for those specific models.

Who this fits and who it does not

Owners of the listed Pavilion 14-al laptops who need a single 4GB stick to fill an empty slot or replace a failed one will find this module works without configuration. Systems that require ECC, registered DIMMs, a different voltage, a higher speed grade or a capacity above 4GB per slot cannot use this part. Buyers with other laptop families or desktop boards should verify their platform specifications first.

Speed and form factor decide compatibility

The module is a 260-pin DDR4 SODIMM rated at PC4-17000 2133MHz CL15. That exact speed, pin count and latency combination must match the memory controller and slot keying of the target machine. If the service manual calls for a different DDR4 rate, a different CAS value or a 288-pin DIMM, this stick will not seat or will not train correctly.
