32GB DDR5 4800 SODIMM for HP laptops

This 32GB DDR5 4800 CL40 SODIMM operates at 1.10V and uses a 262-pin unbuffered non-ECC design. It is built as a direct replacement for HP part numbers N23053-001, N05331-001 and 5S4C0AA and targets owners of compatible HP laptops, notebooks or all-in-one PCs who need a single high-capacity module.

Ideal for HP systems specifying this exact part

Buyers whose HP service manual lists N23053-001, N05331-001 or 5S4C0AA can install this module with confidence. Systems that require ECC or registered memory cannot use this unbuffered non-ECC stick, and laptops with soldered memory or no accessible SO-DIMM slot have no way to add it.

DDR5 4800 CL40 at 1.10V decides fit

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of 40 and a standard DDR5 voltage of 1.10V. If your HP laptop demands a different speed, voltage or latency the module will not meet the required specification.
