Kit purpose and target system

This 768GB kit contains sixteen 48GB DDR5 RDIMMs built for the Supermicro H14DSH motherboard. It serves administrators who must populate every slot with registered ECC memory that the platform recognises at full capacity and rated speed.

Build quality and connector implications

Each module uses a 288-pin registered DIMM interface with a 2Rx8 organisation and operates at 1.1V. The registered architecture buffers address and command signals so the memory controller remains stable when all slots are filled, while on-die ECC corrects single-bit errors before they affect workloads.

Bundled contents and practical effect

The package delivers the complete 16-module set matched to the board's population rules, removing the need to source individual sticks or verify rank compatibility manually. Technical support is available for installation guidance and configuration checks.

Questions about this item

What DDR5 speed and bandwidth does this 4800MHz CL40 kit actually deliver?

The kit runs at DDR5-4800 (PC5-38400) with CL40 latency at 1.10V, so the memory controller sees the rated 4800 MT/s throughput across all 16 modules.

Will these 288-pin RDIMMs fit the Supermicro H14DSH slots and clear the CPU coolers?

Yes — they are 288-pin registered RDIMMs, the exact form factor the H14DSH requires; with no heat spreaders they sit low enough for standard server heatsinks.

What is the correct population order for all 16 slots on the H14DSH?

Consult the Supermicro H14DSH manual for the approved DIMM population sequence; the board’s memory-controller rules dictate which of the 16 slots must be filled first for full 768GB operation.
