Hynix HMT31GR7BFR4A-H9T7AC 8GB

Product Description

Hynix (SK Hynix) 8GB DDR3 ECC Registered RDIMM – 1Rx4 Organization

This Hynix HMT31GR7BFR4A-H9T7AC is an 8GB DDR3 server memory module with ECC. Featuring a 1Rx4 (Single Rank, x4) organization and 1333MHz speed, it is designed for performance and compatibility in a wide range of legacy enterprise servers where single-rank modules are specified for optimal memory channel loading.

Key Specifications:

• Capacity: 8GB

• Type: DDR3 SDRAM with ECC

• Speed: 1333 MHz (PC3-10600R)

• Voltage: 1.5V

• Module Type: 240-pin ECC Registered DIMM (RDIMM)

• Organization: 1Rx4 (Single Rank, x4)

• Part Number: HMT31GR7BFR4A-H9T7AC

Compatibility & Applications:

• Target Systems: Broadly compatible with DDR3-era servers such as Dell PowerEdge R610/R710, HP ProLiant DL360p/380p G7, IBM/Lenovo System x3550 M3, and Supermicro X9 series motherboards.

• Optimal Use: Ideal for maintaining or upgrading older virtualization hosts, database servers, and application servers where 8GB 1Rx4 RDIMMs are a standard building block for memory configurations.

• ⚠ Important Note: 1Rx4 modules have specific population rules and are often used to maximize the number of DIMMs per channel. Mixing different ranks (e.g., 1Rx4 with 2Rx8) within the same memory channel is typically not supported.
