  • 5 TB total capacity from twelve 128 GB modules for maximum server density
  • DDR5-4800 PC5-38400 speed with CL40 latency matches rated controller timing
  • Registered ECC RDIMM design offloads the controller and corrects single-bit errors
  • 1 V operation at 2Rx4 rank fits Supermicro H14DST-F memory rules
  • 288-pin RDIMM form factor ensures exact mechanical and electrical compatibility

Exact-Match DDR5 Server Kit

This 1.5TB kit contains twelve 128GB DDR5-4800 registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14DST-F memory controller expects. The modules arrive tested as a matched set so the board recognises the full capacity at rated speed without manual tuning.

Enterprise Workloads Only

Suited for databases, virtualisation clusters and compute nodes that require registered ECC memory and full-slot population on this specific Supermicro platform. Not suited for workstations or desktops that accept only unbuffered UDIMMs, nor for any board that cannot address 128GB dual-rank modules.

Sustained Load Behaviour

Registered buffering reduces electrical load on the controller, allowing all twelve slots to run continuously at 4800MT/s without signal degradation. On-die ECC corrects single-bit errors in real time, preventing silent data corruption during extended heavy-throughput operations.
