  • 768 GB total capacity from twelve 64 GB modules for maximum server density
  • DDR5-5600 speed with PC5-44800 bandwidth matches the platform's rated memory clock
  • CL46 latency at 1.1 V delivers specified timing without voltage overhead
  • Registered ECC 2Rx4 design offloads the controller and corrects single-bit errors on the fly
  • 288-pin RDIMM form factor verified for Supermicro H14DSH motherboard compatibility

Exact-match DDR5 kit for Supermicro H14DSH

This 768GB kit contains 12 modules of 64GB DDR5 5600 PC5-44800 registered ECC RDIMMs. It matches the precise rank, voltage, and timing the H14DSH memory controller expects for full-capacity recognition at rated speed. The 2Rx4 organization and 1.1V operation align with the board's population rules.

Replaces partial or mismatched DDR5 populations

When a server runs with fewer than 12 slots filled or mixes ranks and speeds, the controller downclocks or limits capacity. Installing this complete 12-module kit eliminates those compromises so every channel runs at DDR5 5600 with registered buffering and ECC active. The jump is worth it when the workload demands the full 768GB address space and zero silent data corruption.

768GB headroom for memory-bound workloads

Twelve 64GB dual-rank modules deliver 768GB across all channels, comfortably handling large in-memory databases, virtualization hosts, and HPC datasets that exceed smaller configurations. The registered architecture offloads the controller so every slot stays stable at full population. Capacity runs out when the application working set grows beyond 768GB or the motherboard's maximum supported limit is lower.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H14DSH motherboard slots?

Yes, the kit uses 288-pin DDR5 RDIMM form factor which matches the Supermicro H14DSH motherboard memory slots exactly.

What is the correct installation order for the 12 modules on the Supermicro H14DSH?

Consult the Supermicro H14DSH manual for the approved DIMM population sequence; the board requires specific slot filling order for all 12 modules to be recognised at full 768GB capacity.

Do the Samsung, Micron or Hynix chips on these RDIMMs require any firmware updates or periodic maintenance?

No firmware updates or periodic maintenance are needed for the memory chips; the modules are validated for continuous operation at 1.1V with ECC error correction active.
