Exact-match DDR5 RDIMM kit for Supermicro H14DSH

This 384 GB kit contains twelve 32 GB DDR5 6400 registered ECC modules built to the precise rank, voltage and timing the motherboard expects. It is intended for administrators who need the full memory capacity recognised at rated speed without manual tuning.

DDR5 6400 registered ECC constraints

Registered DIMMs buffer address and command signals so the memory controller can drive all twelve slots at 6400 MT/s with CL52 latency at 1.1 V. ECC corrects single-bit errors on the fly, but the standard does not protect against multi-bit failures or replace the need for regular scrubbing.

Twelve-slot population and verification

Installing twelve identical 288-pin RDIMMs demands strict adherence to the board's population order; a single misplaced module will prevent boot or reduce capacity. Verify the manual's approved sequence and BIOS revision before fitting, as mixed ranks or voltages will cause instability.

Questions about this item

Should I choose the 384GB 12x32GB kit or a different capacity for my Supermicro H14DSH?

The 384GB kit provides 12 modules of 32GB each, filling 12 slots with 2Rx8 registered ECC RDIMMs at 1.1V. Verify your motherboard manual for the approved DIMM population order and maximum supported capacity before purchasing.

What does the DDR5 6400 speed rating mean once installed in the H14DSH?

The modules run at DDR5 6400 (PC5 51200) with CL52 latency at 1.1V. The registered ECC design allows all 12 slots to operate at this rated speed when populated according to the board's memory population rules.

How does the 288-pin RDIMM interface and registered ECC design affect real-world use?

The 288-pin RDIMM form factor fits only registered DIMM slots. Registered buffering reduces electrical load on the memory controller, enabling full 12-slot population at 384GB, while ECC corrects single-bit errors to prevent data corruption and unplanned reboots.
