Exact-fit DDR5 server upgrade

This 128 GB kit delivers two 64 GB DDR5 6400 registered ECC RDIMMs built to the precise 2Rx4 rank, 1.10 V voltage and CL52 timing the Supermicro H13SRA-F and H13SRA-TF memory controllers expect. The modules install in the standard 288-pin slots and run at their rated PC5-51200 speed when populated according to the board's population rules.

For registered-ECC platforms only

Administrators expanding Supermicro H13SRA-F or H13SRA-TF servers with fully populated, error-correcting memory will find the spec-matched kit ready for production workloads. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC memory or consumer DDR5 speeds should select a different product line.

Ready-to-install matched pair

The kit supplies both modules in a single package so the dual-rank configuration reaches full 128 GB capacity without mixing batches. No heat spreaders are included, and no additional software or cables are required beyond the motherboard's standard memory installation procedure.

Questions about this item

Must the Supermicro H13SRA-F motherboard support DDR5 6400 RDIMM memory for this kit to function?

Yes, the motherboard must support DDR5 6400 RDIMM modules. This kit provides 288-pin registered DIMMs at 1.1V with CL52 timing, matching the board's required specifications.

Will these 2Rx4 registered ECC modules work in slots previously filled with 1Rx8 or 2Rx8 RDIMMs on the same board?

The H13SRA-F/TF memory population rules determine mixed-rank support. Consult the motherboard manual for approved DIMM population order before mixing 2Rx4 modules with other ranks.

How can I confirm the kit is running at DDR5 6400 CL52 with ECC active after installation?

Enter the BIOS or use a hardware monitoring tool to verify the memory speed reads 6400 MT/s, CAS latency shows CL52, and ECC status reports as enabled or active.
