The HMA81GU6CJR8N-UH is an 8GB DDR4-2400 Registered ECC SODIMM (Small Outline Dual In-Line Memory Module) memory module manufactured by Hynix Semiconductor. This module is designed for use in servers, networking equipment, and embedded systems requiring high-performance and reliable memory in a compact form factor. The Registered ECC (Error-Correcting Code) functionality provides enhanced data integrity by detecting and correcting single-bit errors. The registered design helps improve signal integrity, making it suitable for systems with limited space and high memory density.

Applications

• Servers: Used in blade servers, microservers, and other space-constrained server environments.
• Networking Equipment: Employed in routers, switches, and other networking devices.
• Embedded Systems: Integrated into industrial computers, medical devices, and other embedded applications.
• Industrial PCs: Used in industrial PCs for reliable operation in harsh environments.

Features

• 8GB Capacity: Provides 8GB of memory capacity.
• DDR4 Technology: Utilizes DDR4 (Double Data Rate 4) technology for high-speed data transfer.
• 2400MHz Clock Speed: Operates at a clock speed of 2400MHz.
• Registered ECC (Error-Correcting Code): Detects and corrects single-bit memory errors, improving data integrity.
• SODIMM Form Factor: Compact form factor suitable for space-constrained applications.
• 260-Pin Connector: Features a 260-pin connector for DDR4 SODIMM memory slots.

Benefits

• Improved Performance: High-speed DDR4 memory enhances system performance.
• Data Integrity: ECC memory ensures data integrity and reduces the risk of data corruption.
• Increased Reliability: ECC and high-quality components contribute to system reliability.

Additional Details

The HMA81GU6CJR8N-UH is designed to operate at a voltage of 1.2V. The module complies with JEDEC standards for DDR4 memory. Hynix datasheets provide detailed information on the timing parameters, power consumption, and thermal characteristics of the memory module. Before installing, it is essential to verify that the target system (server, networking device, or embedded system) supports DDR4 Registered ECC SODIMM memory. The Registered ECC feature is crucial in environments where data corruption can have serious consequences. The 'UH' suffix most likely denotes specific manufacturing or testing parameters, usually associated with the server-grade memory modules. The SODIMM form factor makes it ideal for use in applications requiring a small footprint without sacrificing performance or reliability.
