Exact-match server upgrade

This 48GB DDR5 6400MHz PC5-51200 module is a 2Rx8 Registered ECC RDIMM built to the precise rank, voltage and timing the Supermicro H13SRA-F and H13SRA-TF motherboards expect. It operates at 1.1V with CL52 latency and uses the 288-pin form factor required by these boards so the memory controller recognises full capacity at rated speed.

Ideal for capacity-bound workloads

It suits administrators expanding memory on the listed Supermicro platforms where registered ECC and the 2Rx8 organisation are mandated by the memory population rules. Builders needing unbuffered UDIMMs, SODIMMs, non-ECC modules or a different rank configuration should look elsewhere because this module will not function in those slots.

Verify population rules first

Consult the system or motherboard manual for supported capacities per slot, approved DIMM installation order and any BIOS version requirements before ordering. The registered architecture allows full-slot population but the exact sequence and maximum total capacity are defined by the platform documentation.

Questions about this item

My Supermicro H13SRA-F board needs DDR5 RDIMMs — will this 48GB 6400MHz kit work without a BIOS update?

The module is spec-matched to the Supermicro H13SRA-F and H13SRA-TF motherboards at DDR5 6400 PC5-51200, 2Rx8 registered ECC, 1.1V, CL52, so the board's memory controller recognises it at full capacity and rated speed.

If I populate the remaining slots with other DDR5 RDIMMs of different rank or speed, what happens?

Registered architecture offloads the memory controller, but mixed ranks or speeds force all channels to the lowest common speed and may violate the board's population rules — check the manual for approved DIMM order.

After installation, how do I confirm the kit is running at 6400MHz with ECC active?

In the BIOS or UEFI, verify the memory frequency reads 6400 MT/s (PC5-51200), CAS latency shows CL52, voltage reads 1.1V, and ECC status reports enabled or active.
