  • 576 GB total capacity from six 96 GB modules for large-scale workloads
  • DDR5 4800 speed rated at PC5-38400 for high bandwidth
  • Registered ECC design with 2Rx4 organisation corrects single-bit errors on the fly
  • 1 V operation at CL40 latency matches the controller's exact timing
  • Verified fit for Supermicro H14DST-F using 288-pin RDIMM form factor

Exact-match server upgrade

This 576GB kit contains six 96GB DDR5 4800 Registered ECC RDIMMs built for the Supermicro H14DST-F motherboard. The 2Rx4 organisation, 1.10V operating voltage and CL40 timing match the board's memory controller requirements so the full capacity is recognised at rated speed. It is not suited to workstations or desktops that accept only unbuffered UDIMM modules.

Thermals and power

Registered buffering reduces the electrical load on the memory controller, allowing all slots to run fully populated without signal degradation. The 1.10V DDR5 baseline keeps per-module power draw low, and the absence of a heat spreader means airflow across the bare PCB handles normal server chassis cooling. No active cooling or extra voltage headroom is required for standard operation.

Build and connectors

Each module uses the 288-pin RDIMM form factor keyed for DDR5 server boards, so it cannot be inserted into UDIMM or SODIMM slots. The six-DIMM kit fills a typical multi-channel population sequence, but the exact slot order must follow the motherboard manual. Samsung, Micron or Hynix major-OEM DRAM chips are used depending on supply, all meeting the same registered ECC specification.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules in the Supermicro H14DST-F and what population order does the manual require?

The kit contains six 96GB 2Rx4 registered DIMMs; install them in the exact slot sequence shown in the H14DST-F manual so the memory controller recognises the full 576GB at DDR5 4800.

What ongoing maintenance or replacement will the 576GB DDR5 4800 ECC RDIMM kit need?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and a module is only replaced if it develops uncorrectable faults.

What limit appears first when the 6×96GB 2Rx4 RDIMM kit runs sustained workloads at 1.1V?

The memory controller's maximum supported capacity and rank-per-channel limit is reached before thermal or voltage headroom becomes an issue.
