Hynix HMCT14AGERA206N 256GB PC5-44800 DDR5-5600MHz 8Rx4 ECC

Description

The SK Hynix HMCT14AGERA206N is a next-generation, ultra-high-density DDR5 memory module designed for the most demanding enterprise server environments. It combines a massive 256 GB capacity with a high-speed 5600 MT/s data rate, making it ideal for AI training, large-scale virtualization, and high-performance computing (HPC).

Technical Specifications

Advanced Architecture and Benefits

3DS (Three-Dimensional Stacking)

To reach the 256 GB capacity on a single module, Hynix utilizes 3DS technology with Through-Silicon Via (TSV) interconnects. This allows the vertical stacking of DRAM dies, achieving extreme density without exceeding the physical dimensions of a standard DIMM. The 8Rx4 configuration indicates eight logical ranks, optimized for high-capacity memory mapping.

Increased Bandwidth (5600 MT/s)

Operating at 5600 MT/s (PC5-44800), this module offers a significant performance boost over standard 4800 MT/s DDR5 memory. This increased bandwidth is critical for feeding data to modern processors with high core counts, reducing bottlenecks in data-heavy workloads.

Power Management and Reliability

• On-DIMM PMIC: Features a dedicated Power Management Integrated Circuit on the module. This provides more efficient and stable power delivery directly to the DRAM, which is vital for maintaining the integrity of 256 GB of data at high speeds.

• On-Die ECC: This module includes internal error correction within the chips themselves, complementing the standard system-level ECC for maximum protection against bit-flips and data corruption.

   

• Dual 32-bit Sub-channels: The DDR5 architecture utilizes two independent 32-bit sub-channels per DIMM, doubling the access efficiency and reducing latency compared to DDR4.

Compatibility and Platforms

The HMCT14AGERA206N is a Registered DIMM (RDIMM). It is exclusively compatible with high-end server platforms that support DDR5-5600 speeds, such as:

• Intel: 5th Gen Xeon Scalable (Emerald Rapids) and Xeon 6 (Sierra Forest / Granite Rapids).

• AMD: EPYC 9004 Series (Genoa / Bergamo) that are validated for 5600 MT/s operation.
