Server Memory Kit for Supermicro H13DSH

This 576GB kit contains twelve 48GB DDR5 RDIMM modules built for the Supermicro H13DSH motherboard. Registered ECC architecture and a 1.1V operating voltage match the board's memory controller requirements for full-capacity operation. System administrators scaling database or virtualization workloads gain the registered buffering needed when every slot is populated.

Registered ECC Changes Data Integrity

Registered buffering reduces electrical load on the memory controller so all twelve slots run at the rated 6400MHz speed without signal degradation. ECC corrects single-bit errors in real time, preventing silent data corruption that can halt production services. The CL52 timing and 2Rx8 organization are the exact parameters the platform expects for stable operation.

Verify Motherboard Population Rules

The Supermicro H13DSH manual defines supported capacities, approved DIMM population order, and installation steps that must be followed before ordering. Registered RDIMM form factor is required; UDIMM or SODIMM modules will not fit the 288-pin slots. Confirm your specific BIOS revision and CPU configuration support the full 576GB capacity.

Questions about this item

Will the 12 RDIMM modules need any firmware updates or periodic replacement during their service life?

The modules are a 12 x 48GB DDR5 6400MHz CL52 1.10V 2Rx8 288-pin ECC Registered kit verified for the Supermicro H13DSH; they require no firmware updates and are covered by a lifetime replacement warranty.

What limits sustained throughput when all 12 slots are populated at DDR5-6400?

The registered ECC architecture offloads the memory controller so every slot runs fully populated at the rated 6400MHz speed without down-clocking.

How much heat and power does the 576GB kit generate when running continuously at 1.10V?

Each module operates at 1.10V without a heat spreader; the registered design keeps per-DIMM power low enough for standard server airflow to handle continuous operation.
