Exact-match upgrade for Supermicro H14DSH

This 512GB kit delivers four 128GB DDR5 4800 modules built to the precise rank, voltage and timing the H14DSH memory controller expects. Registered ECC RDIMM architecture ensures every slot runs fully populated at rated speed. The modules arrive new and ready for immediate installation in compatible systems.

2Rx4 registered ECC at 1.1V

Each DIMM uses a dual-rank 2Rx4 organisation with registered buffering and on-die ECC operating at 1.10V. This combination offloads the controller, corrects single-bit errors on the fly and prevents silent data corruption across the full 512GB capacity. The 288-pin DDR5 form factor matches the board's physical and electrical requirements exactly.

Sustained stability under full population

Registered buffering maintains signal integrity when all channels are loaded, so throughput remains consistent during long compute runs rather than throttling after a short burst. ECC continues to catch and correct errors throughout extended workloads, protecting data integrity without unplanned reboots. The kit is validated for continuous operation in the target platform.

Questions about this item

How does the 4800 MT/s DDR5 speed behave once the four 128 GB modules are installed in a Supermicro H14DSH?

The kit runs at DDR5-4800 (PC5-38400) with CL40 timing at 1.1 V; the registered design lets all four slots operate at the rated frequency without down-clocking.

What does the 288-pin RDIMM interface cap in practice for this server board?

The 288-pin registered form factor is exactly what the H14DSH requires; it prevents use of UDIMM or SODIMM modules and ensures the memory controller recognises the full 512 GB capacity.

What physical clearance does the 2Rx4 128 GB module need to fit the H14DSH memory slots?

Each module is a standard-height 288-pin RDIMM without a heat spreader, so it fits the H14DSH DIMM sockets as long as the board's population order is followed.
