Exact-match DDR5-6400 upgrade for Supermicro H13SRA

This 32 GB kit contains two 16 GB DDR5-6400 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SRA-F and H13SRA-TF memory controllers expect. Registered ECC architecture ensures every slot runs fully populated at rated speed while correcting single-bit errors before they reach production workloads.

Registered RDIMM form factor and 1.10 V operation

The 288-pin registered modules fit only boards wired for RDIMMs — they will not seat in UDIMM or SODIMM slots. Buffered signalling offloads the memory controller, allowing full-capacity population without signal degradation, and the low 1.10 V supply matches the platform's native voltage rail.

DDR5-6400 bandwidth ceiling and population rules

The PC5-51200 interface caps throughput at the JEDEC DDR5-6400 rate, so faster modules would downclock to this limit. Server manuals dictate specific slot-filling sequences and maximum per-channel capacities; exceeding those rules prevents boot or reduces performance.

Questions about this item

What DDR5 speed and PC5 rating does this 32GB kit run at?

The kit operates at DDR5 6400 with a PC5-51200 data rate, delivering the exact bandwidth the Supermicro H13SRA-F/TF memory controller expects.

What physical slot and form factor are required to install these modules?

Each module is a 288-pin RDIMM; the motherboard must provide matching DDR5 RDIMM slots — UDIMM or SODIMM sockets will not accept them.

How do I install the two 16GB sticks in the correct population order?

Consult the Supermicro H13SRA-F/TF manual for the approved DIMM sequence, then seat both 1Rx8 registered modules firmly until the retention clips lock on each end.
