512GB DDR5 RDIMM kit for Supermicro H13DSH

This 512GB kit contains 16 registered ECC DDR5 RDIMMs, each 32GB, built to the exact DDR5-4800 PC5-38400 specification the Supermicro H13DSH motherboard requires. The 2Rx8 organisation, 1.1V operation and CL40 timing match the board's memory controller expectations so the full capacity is recognised at rated speed. It is intended for administrators upgrading a compatible Supermicro server to its maximum supported memory.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing all 16 slots to remain fully populated at DDR5-4800 without downclocking during extended workloads. ECC circuitry detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots that would otherwise interrupt production services. The modules operate at the standard 1.1V DDR5 voltage throughout continuous operation.

Verify DIMM population rules before ordering

Server memory support varies by model and BIOS revision, so consult the Supermicro H13DSH manual for approved capacities, slot population order and any firmware requirements before purchase. The kit uses 288-pin RDIMMs only; UDIMM or SODIMM modules are physically and electrically incompatible. Ensure your chassis and airflow can accommodate 16 dual-rank modules running continuously.

Questions about this item

How much power does the 1.1 V DDR5 kit draw when all 16 modules run continuously in a fully populated server?

Each module operates at 1.1 V and the registered design reduces electrical load on the memory controller, allowing all 16 slots to run at the rated 4800 MT/s without exceeding the platform's power budget.

Does the Supermicro H13DSH motherboard need a specific BIOS revision or CPU generation to recognise the full 512 GB kit?

The kit is validated for the H13DSH platform; the motherboard manual defines the supported DIMM population order and any BIOS version required for 32 GB registered DIMMs.

Will these 2Rx8 CL40 RDIMMs run at 4800 MT/s if I keep lower-capacity DDR5 modules in the remaining slots?

The memory controller will train all installed DIMMs to a common speed; mixing ranks or capacities can force the kit to run below its rated 4800 MT/s, so the manufacturer recommends a matched 16-module kit for full performance.
