576GB DDR5 5600 ECC RDIMM Kit

This 576GB kit contains twelve 48GB DDR5 5600MHz registered ECC RDIMMs built for the Supermicro H13SST-G motherboard. It targets administrators who need maximum registered memory capacity on that platform. The modules operate at 1.1V with CL46 latency and a 2Rx8 organisation. They are designed for server workloads that demand error correction and full-slot population.

288-Pin Registered Form Factor Fit

The 288-pin RDIMM form factor matches the H13SST-G memory slots exactly; UDIMM or SODIMM modules will not fit. Registered buffering reduces electrical load on the memory controller so all twelve slots can be populated at rated speed. ECC circuitry corrects single-bit errors in flight to protect data integrity. No heat spreaders are included, so chassis airflow must cool the bare modules.

576GB Capacity Headroom

Twelve 48GB modules deliver 576GB total, allowing large in-memory databases, virtualisation hosts or HPC datasets to reside in RAM. The 2Rx8 rank structure and 1.1V operation keep power draw predictable across a fully populated board. Capacity scales no further on this kit; systems needing more memory would require a motherboard with additional slots or higher-density DIMMs.

Questions about this item

What is the registered ECC DDR5 capacity and speed limit when all twelve slots on the Supermicro H13SST-G are populated?

The kit provides 576GB total across twelve 48GB modules running at DDR5 5600 (PC5-44800) with CL46 timing at 1.1V, the exact specification the board expects for full-capacity operation.

How do the modules behave thermally and acoustically when the server runs continuously without heat spreaders?

Registered DIMMs offload the memory controller so every slot stays stable at full load, while the 1.1V DDR5 voltage keeps power draw low; with no moving parts the memory itself adds no audible noise.

Which motherboard and form factor must already be installed for this 288-pin RDIMM kit to function?

A Supermicro H13SST-G motherboard with twelve DDR5 RDIMM slots is required; the modules are 288-pin registered ECC and will not fit UDIMM or SODIMM sockets.
