Hynix HMA451R7MFR8N-TFTDAA 4GB

Product Description

Hynix (SK Hynix) 4GB DDR4 ECC Registered RDIMM – High-Speed, Low-Density

This Hynix HMA451R7MFR8N-TFTDAA is a distinctive server memory module that combines high 3200MHz speed with a very low 4GB capacity. As a 1Rx8 (Single Rank, x8) ECC Registered RDIMM, it is engineered for niche applications where memory channel population and raw speed are prioritized over total capacity, such as in certain high-performance computing (HPC) or specialized OEM configurations.

Key Specifications:

• Capacity: 4GB

• Type: DDR4 SDRAM with ECC

• Speed: 3200 MHz (PC4-25600R)

• Voltage: 1.2V

• Module Type: 288-pin ECC Registered DIMM (RDIMM)

• Organization: 1Rx8 (Single Rank, x8)

• Part Number: HMA451R7MFR8N-TFTDAA

Compatibility & Applications:

• Target Systems: Likely used in latest-generation servers from OEMs like Dell (PowerEdge 15G/R750), HPE (Gen10 Plus/Gen11), or Supermicro (X12/X13) that support 3200MHz memory and were configured for specific low-latency or high-bandwidth tasks.

• Primary Use: Specialized/OEM configurations only. This module is not a standard upgrade part. Its value lies in exact replacement for failed modules in existing systems, or for building custom configurations that require populating all memory channels with single-rank modules at maximum speed.

• Critical Note: The 3200MHz speed requires a compatible server platform (CPU & motherboard). Mixing speeds will cause all memory to run at the lowest common denominator.
