Capacity and Form Factor

This 48 GB DDR5 module uses the 262-pin SO-DIMM layout built for laptops, notebooks and all-in-one computers. It delivers a single 48 GB stick rated at 4800 MHz with CL40 latency and standard 1.10 V operation.

Compatibility Check

Verify that your system supports DDR5 SO-DIMM memory at 4800 MHz and accepts a non-ECC, unbuffered module of this capacity before ordering. The motherboard must provide a 262-pin slot and run at the standard 1.10 V DDR5 voltage.

Build Integration

The module installs directly into an available SO-DIMM slot and requires no heat spreader or additional cooling hardware. Adding 48 GB in one stick leaves any second slot free for future expansion while immediately raising the memory ceiling for multitasking and heavier workloads.
