Exact-match server kit

This 512GB kit delivers four 128GB DDR5 RDIMMs running at 6400 MT/s with CL52 latency and 1.1V operation. Registered ECC architecture and 2Rx4 rank organisation provide the signal integrity and error correction required by Supermicro H13SRA-F and H13SRA-TF motherboards.

Upgrade path and fitment

The kit replaces partial or slower DDR5 populations to reach full capacity at the board-rated speed. The jump is worth it when your workload needs maximum registered DIMM slots populated with matched rank, voltage and timing so the memory controller recognises every module without downclocking.

Pre-install checklist

Verify your motherboard manual for approved DIMM population order and maximum supported capacity per slot. Confirm the system requires 288-pin Registered ECC RDIMMs rather than unbuffered or SODIMM form factors. Ensure the BIOS version in use supports the full 512GB configuration at 6400 MT/s.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SRA-F motherboard DIMM slots?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor that the H13SRA-F and H13SRA-TF boards require; it is not a UDIMM or SODIMM.

What is the correct population order for the four 128 GB modules on these Supermicro boards?

Consult the motherboard manual for the approved DIMM population sequence; the kit is spec-matched to the board's memory-population rules.

Do the modules need active cooling since they have no heat spreader?

The modules ship without a heat spreader; rely on the server chassis airflow and follow the system vendor's thermal guidelines for fully populated RDIMM configurations.
