HMT31GR7BFR4A-H9 Hynix 1x8GB DDR3 RDIMM ECC RAM

Enterprise DDR3L RDIMM Server Memory Module for Legacy Platforms with the HMT31GR7BFR4A-H9

The HMT31GR7BFR4A-H9 is an 8GB DDR3L ECC Registered DIMM designed to keep DDR3-based server estates stable, serviceable, and consistent across mixed node populations. As a 240-pin RDIMM, it targets platforms where registered buffering is required for signal integrity at scale, supporting predictable memory behavior in older Intel Xeon and AMD Opteron generations.

Built around JEDEC DDR3-1333 (PC3L-10667R) operation at 1.35V, the HMT31GR7BFR4A-H9 balances performance and power within legacy constraints while maintaining ECC protection across a 72-bit data path. Registered architecture helps preserve timing margins when populating multiple DIMM slots per channel, and the dual-rank layout improves compatibility with common DDR3 server memory routing and controller limits. The low-profile module height with heat spreader supports dense 1U/2U deployments and airflow-managed chassis designs, making the HMT31GR7BFR4A-H9 a practical spare for maintaining PCIe-era expansion and SATA/SAS storage nodes that must remain in production.

Why Choose the HMT31GR7BFR4A-H9?

The HMT31GR7BFR4A-H9 provides a controlled path to extend the lifecycle of DDR3 infrastructures by delivering server-grade ECC RDIMM reliability with registered buffering for higher slot population stability. It supports standardized refresh and replacement practices, enabling consistent capacity planning and minimizing downtime risk during maintenance windows.

Hynix memory engineering emphasizes validated component selection, tight process control, and compliance with modern data center handling expectations, including RoHS and halogen-free/lead-free requirements for enterprise supply chains.

Key Applications:

• Legacy DDR3 server maintenance and spares
• Virtualization hosts on DDR3 platforms
• General-purpose compute on older Xeon/Opteron
• Entry databases and infrastructure services
