Supermicro H13SSH 384GB DDR5 kit

This NEMIX RAM kit delivers 384GB across six 64GB DDR5-5600 Registered ECC RDIMMs built for the Supermicro H13SSH motherboard. Each module runs at 1.1V with CL46 timing and a 2Rx4 organisation. The registered design is required by the board's memory controller for full-capacity operation.

Sustained-load behaviour

Registered architecture buffers every command so all six slots stay stable at the rated 5600 MT/s during continuous server workloads. On-die ECC corrects single-bit errors in real time, preventing silent data corruption that would otherwise trigger unplanned reboots under heavy utilisation.

Installation notes

The 288-pin RDIMM form factor fits only the H13SSH's DDR5 RDIMM slots; UDIMM or SODIMM modules will not seat. Consult the motherboard manual for the approved population sequence before installing all six modules. No heat spreaders are present, so ensure adequate chassis airflow over the bare PCBs.

Questions about this item

How much heat or power draw should I expect from this 384GB DDR5-5600 kit running 24/7 in a Supermicro H13SSH?

Each 64GB module operates at 1.10V with a CL46 timing; the registered design reduces electrical load on the memory controller, so total power scales with the six 2Rx4 DIMMs installed.

What must my Supermicro H13SSH already have for this 6x64GB RDIMM kit to be recognised at full capacity?

The board needs all six 288-pin DDR5 RDIMM slots free and a BIOS that supports 384GB of registered ECC memory populated per the manual's population order.

Will these 5600MHz CL46 modules downclock reliably if I keep older DDR5 DIMMs in the same H13SSH?

The kit is validated for DDR5-5600 at 1.1V; mixing ranks or speeds forces the controller to run every slot at the lowest common speed and voltage.
