Restore usable headroom in older notebooks and compact systems with this 4 GB DDR4 SoDIMM from EDGE Tech. Built to PC4-2133 specifications, it delivers 2,133 MHz transfer rates in a 260-pin, 1.2 V module designed for compatible laptop memory slots. This module is a practical choice when a system needs more breathing room for everyday productivity, browser tabs, email, and light business applications. The non-ECC design fits standard client platforms that do not require server-grade error correction, while the single-module configuration keeps installation simple. For IT teams supporting mixed fleets, this part is useful when extending the service life of legacy mobile hardware where a full refresh is not yet justified. It provides a measured capacity increase without overspending on features the platform cannot use. When the goal is to keep endpoints productive and stable, a verified-fit memory upgrade is often the most cost-effective path.
