Exact-match DDR5 upgrade for Supermicro H13SSF

This 48 GB DDR5-4800 Registered ECC RDIMM is built to the precise rank, voltage and timing the Supermicro H13SSF memory controller expects. It installs as a single 288-pin module and is recognised at full capacity without manual configuration.

Registered architecture for full-slot populations

The registered buffer offloads the memory controller so every slot can run fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption and unplanned reboots in production workloads.

48 GB capacity at CL40 1.1 V

The module delivers 48 GB of DDR5 memory at PC5-38400 with CL40 latency and 1.10 V operation. It suits workloads that fit within a single 48 GB DIMM; systems needing more total memory will require additional qualified modules.

Questions about this item

Will the 48GB DDR5 4800MHz CL40 2Rx8 module run at full rated speed when all slots on the Supermicro H13SSF are populated?

Yes, the registered architecture offloads the memory controller so every slot can run fully populated at the rated 4800MHz speed and 48GB capacity.

How much power does each 48GB DDR5 module draw at the specified 1.1V operating voltage during continuous operation?

The module operates at 1.1V DDR5 standard voltage; registered buffering reduces electrical load on the motherboard for stable all-day operation.

Does the Supermicro H13SSF motherboard require registered ECC RDIMMs for this 48GB DDR5 upgrade to function correctly?

Yes, the H13SSF requires 288-pin registered ECC RDIMMs; this 2Rx8 CL40 module matches the exact form factor and ECC type the board expects.
