Supermicro H13SSF DDR5 upgrade

This 256 GB kit (2 x 128 GB) is built for the Supermicro H13SSF motherboard. It uses the 288-pin DDR5 RDIMM form factor that the board requires and matches the exact rank, voltage and timing the memory controller expects.

Capacity and registered headroom

Two 128 GB registered ECC modules give 256 GB total, allowing full population of supported slots at rated DDR5-4800 speed. Registered architecture offloads the memory controller so every slot runs fully populated, while ECC corrects single-bit errors on the fly. Systems needing more memory than the board supports or requiring unbuffered UDIMMs cannot use this kit.

Thermals and power draw

Modules operate at 1.10 V with CL40 latency and no heat spreaders, relying on server chassis airflow for cooling. The low voltage and registered design keep power draw modest under normal loads, while the bare PCB allows unrestricted airflow in dense configurations.

Vragen over dit artikel

Will this 256GB DDR5 4800 ECC RDIMM kit work with existing DDR5 modules in my Supermicro H13SSF?

Mixing kits is not recommended. The H13SSF requires registered ECC RDIMMs with matching 2Rx4 rank, 1.1V voltage, and CL40 timing for stable operation across all populated slots.

How can I confirm the 2x128GB modules are running at DDR5 4800 with ECC active after installation?

Enter the BIOS and verify the memory speed shows 4800 MT/s, total capacity reads 256GB, and ECC status is enabled. The registered design also reduces electrical load for reliable full-population operation.

Does the MR38400-724K2 kit include heat spreaders or any cables, or just the two 288-pin RDIMMs?

The package contains only the two 128GB DDR5 4800 ECC registered RDIMMs. No heat spreaders, cables, or additional accessories are included with this kit.
