Exact-match server kit

This 64GB kit contains four 16GB DDR5 6400 RDIMMs built to the exact rank, voltage and timing the Supermicro H13SRA-F and H13SRA-TF memory controllers expect. Registered ECC architecture offloads the controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly. The 1.1V CL52 specification matches the board's native profile without manual tuning.

Sustained enterprise stability

Registered buffering keeps electrical load low across all four slots during continuous multi-threaded workloads, preventing the signal degradation that can appear when consumer modules fill every channel. ECC detection and correction operates transparently under sustained write pressure, stopping silent data corruption before it reaches storage or network layers. The 1Rx8 organisation maintains consistent latency across the full 64GB capacity during long-running compute or virtualization tasks.

DDR5 platform limits

DDR5 6400 (PC5-51200) is the maximum JEDEC speed this motherboard family supports with four ranks populated, so the kit cannot run faster without exceeding the platform's qualified memory controller specification. The 288-pin RDIMM form factor is mandatory; UDIMM or SODIMM modules will not fit the server's DIMM slots. Consult the Supermicro manual for approved population order and maximum supported capacity per channel before installation.

Questions about this item

Does the 1.1 V DDR5 kit run cool enough for a fully populated server chassis?

The modules operate at 1.1 V with no heat spreader, so they rely on the chassis airflow that Supermicro specifies for the H13SRA-F and H13SRA-TF platforms.

What motherboard slot type must my system provide for these 288-pin RDIMMs?

The kit requires DDR5 RDIMM slots on a Supermicro H13SRA-F or H13SRA-TF motherboard; UDIMM or SODIMM sockets will not accept the 288-pin registered form factor.

Can I mix the 1Rx8 Registered ECC modules with unbuffered UDIMMs already installed?

No, the registered architecture and ECC function are only supported when every populated slot uses matching RDIMMs; mixing with unbuffered memory will prevent the system from booting.
