The HMA81GU7AFR8N-UH is an 8GB DDR4 2133MHz Unbuffered DIMM (UDIMM) memory module manufactured by Hynix Semiconductor. This module is typically used in desktop computers and entry-level servers. While it lacks ECC (Error Correcting Code) functionality, it provides a cost-effective memory solution for general computing tasks. The absence of ECC makes it less suitable for critical server applications where data integrity is paramount.

Applications

• Desktop Computers: Used in consumer and business desktop computers for general office productivity, web browsing, and multimedia applications.
• Entry-Level Servers: Suitable for entry-level servers with light workloads where ECC memory is not strictly required.
• Small Business Servers: Employed in small business servers for file sharing, print services, and basic application hosting.
• Home Servers: Integrated into home servers for media streaming, file storage, and personal cloud services.
• Gaming PCs: Used in gaming PCs to provide sufficient memory for running games and other entertainment applications.

Features

• 8GB Capacity: Provides a good amount of memory for most general computing tasks.
