Supermicro H14DSH memory kit

This 1.5TB kit contains twelve 128GB DDR5 RDIMM modules built for the Supermicro H14DSH motherboard. It targets administrators who need the maximum registered ECC capacity this platform supports in a single validated package.

Registered ECC for full-slot population

The 288-pin RDIMM form factor and registered architecture let the memory controller drive all twelve slots at the rated 5600 MT/s without signal degradation. ECC corrects single-bit errors on the fly, and the 1.1V operating voltage matches the board's native DDR5 specification.

Sustained throughput at CL46

CAS latency of 46 cycles at DDR5-5600 delivers consistent bandwidth during long-running workloads such as database serving or virtualization. The 2Rx4 organization maintains stable timing across every rank when the system remains fully populated under continuous load.

Questions about this item

Will the 1.5 TB kit run at full DDR5 5600 speed when all 12 slots are populated?

Yes, the registered ECC design lets every DIMM operate at 5600 MT/s even with all twelve modules installed.

Does this RDIMM kit generate noticeably more heat or fan noise than a smaller configuration?

Each module draws 1.1 V and has no heat spreader, so thermal load scales with capacity but stays within standard server airflow limits.

Must the Supermicro H14DSH already have a specific BIOS version or CPU stepping to recognise the full 1.5 TB?

The kit is validated for the H14DSH; consult the motherboard manual for any required BIOS updates before installing all twelve DIMMs.
