NEMIX RAM 64GB (4x16GB) DDR5 6400 CL52 1.1V ECC RDIMM 1Rx8 288-pin memory upgrade

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.
