Supermicro H13DSH DDR5-4800 ECC RDIMM Kit

This 32 GB kit contains two 16 GB registered ECC DDR5 modules built to the exact specifications required by the Supermicro H13DSH motherboard. It is intended for server administrators who need to populate memory slots with validated, error-correcting DIMMs for production workloads.

288-Pin Registered DDR5 Form Factor

Each module uses the 288-pin RDIMM interface with a registered buffer that reduces electrical load on the memory controller when all slots are filled. The 1.1 V operating voltage and CL40 latency match the board's native DDR5-4800 timing, allowing the system to recognise the full 32 GB capacity at rated speed without manual tuning.

Major OEM DRAM Components

The kit is assembled with Samsung, Micron or Hynix DRAM chips selected for enterprise-grade stability. This component choice supports the registered ECC architecture that corrects single-bit errors automatically, helping prevent silent data corruption during continuous operation.

Questions about this item

What sustained-throughput limit appears first when the DDR5-4800 1.1V registered ECC kit runs continuous server workloads?

The DDR5-4800 modules operate at 4800 MT/s with CL40 latency and 1.10V, so the memory-controller bandwidth ceiling is reached before thermal or power limits on the registered DIMMs.

How much heat and noise does the 288-pin RDIMM kit add when the Supermicro H13DSH runs all day?

The kit has no heat spreader and draws 1.10V at DDR5-4800 speeds; registered buffering reduces electrical load on the CPU memory controller, keeping thermal and acoustic impact minimal.

Which motherboard slot layout and population rules must the Supermicro H13DSH already support for this 2×16GB 1Rx8 kit to work?

The board must provide 288-pin DDR5 RDIMM slots and follow its manual’s approved population sequence for 1Rx8 registered ECC modules at 4800 MT/s.
