8GB DDR5-4800 laptop upgrade

This 8GB DDR5-4800 SO-DIMM targets owners of compatible laptops, notebooks and all-in-one systems who need a straightforward memory increase. The module runs at the standard 1.1V and uses unbuffered, non-ECC architecture with 1Rx16 organisation. It is built as a direct replacement for the Patriot PSD58G480041S part.

262-pin DDR5 SO-DIMM fit

The 262-pin edge connector matches the DDR5 SO-DIMM slot found in supported mobile platforms. No heat spreader is fitted, keeping the profile low for tight chassis clearances. Major-brand DRAM ICs are used throughout and every unit undergoes quality-assurance testing before it leaves the factory.

Replaces Patriot PSD58G480041S

This module replaces the Patriot PSD58G480041S stick when that original part is unavailable or when a single 8GB upgrade is preferred. The jump is worthwhile when the system currently runs less memory or a slower DDR5 speed and the platform supports DDR5-4800 operation. Buyers needing larger capacities or dual-rank configurations should look elsewhere.
