Capacity and fit

This single 48GB module uses the 262-pin DDR5 SO-DIMM form factor built for laptops, notebooks and all-in-one PCs. It targets users who need a large memory upgrade in one slot.

Installation and common issues

The module installs like any standard SO-DIMM: power off the device, open the memory door, align the notch and press until the clips lock. Compatibility varies by system, so verify the supported memory specifications before purchase to avoid a mismatch.

Deciding specification

The memory runs at DDR5 4800 with CL40 latency at 1.10V and is a non-ECC, unbuffered 2Rx8 dual-rank design. If your platform requires ECC, registered DIMMs, a different speed or a lower capacity per slot, this is not the right part.
