Server Memory Kit for Supermicro H13SSF

This 256GB kit contains eight 32GB DDR5 registered ECC RDIMMs built for the Supermicro H13SSF motherboard. It targets administrators who need to populate every slot with validated modules that the board recognises at full capacity.

Registered ECC with 2Rx8 organisation

Each module is a 288-pin DDR5 RDIMM running at 4800 MT/s (PC5-38400) with CL40 latency at 1.1V. The registered buffer and dual-rank 2Rx8 layout match the memory controller requirements so the system boots at rated speed without down-clocking.

Low-voltage operation and thermal profile

The 1.1V supply keeps power draw modest per module and registered buffering reduces electrical load on the memory controller. No heat spreaders are fitted; airflow across the bare PCB in a server chassis is sufficient for normal sustained workloads.

Questions about this item

What does the 4800 MHz rating deliver once the kit is installed in the Supermicro H13SSF?

The modules run at DDR5-4800 (PC5-38400) with CL40 latency and 1.1 V, so the memory controller sees the exact speed, timing and voltage it expects for full 256 GB capacity.

How does the 288-pin RDIMM interface and registered design affect real-world use?

The 288-pin registered DIMM format offloads the memory controller, allowing all eight slots to be populated at 32 GB each while ECC corrects single-bit errors on the fly.

What physical clearance and slot layout does the 8 x 32 GB kit need on the H13SSF?

Each 288-pin RDIMM occupies one standard DDR5 DIMM slot; the board must support eight registered modules in its approved population order for the full 256 GB kit.
