Exact-match DDR5 kit for Supermicro H13SSW

This 64GB kit contains two 32GB DDR5 RDIMMs rated at 6400MT/s with CL52 latency and 1.1V operation. Registered ECC architecture and 2Rx8 organisation match the memory controller requirements of the Supermicro H13SSW motherboard so the system recognises the full capacity at rated speed.

288-pin RDIMM form factor and registered design

The modules use the 288-pin RDIMM form factor required by the H13SSW, not UDIMM or SODIMM. Registered buffering reduces electrical load on the memory controller allowing every slot to run fully populated while on-die ECC corrects single-bit errors to prevent silent data corruption and unplanned reboots in production workloads.

Samsung Micron or Hynix chips with lifetime support

Major OEM DRAM from Samsung, Micron or Hynix underpins the kit and the package includes only the two RDIMMs. Lifetime replacement coverage and free US-based technical support are provided so deployment issues can be resolved without additional cost.

Questions about this item

What DDR5 speed and CAS latency does this 64GB kit run at?

The kit operates at DDR5-6400 (PC5-51200) with a CL52 latency, matching the exact timing the Supermicro H13SSW memory controller expects for full rated performance.

Will these 288-pin RDIMMs physically fit the Supermicro H13SSW motherboard slots?

Yes. The modules are 288-pin Registered DDR5 RDIMMs, the precise form factor the H13SSW requires; they are not UDIMM or SODIMM and will seat correctly in the server's DIMM slots.

In which order should I populate the two 32GB modules on the H13SSW for proper operation?

Consult the Supermicro H13SSW manual for the approved DIMM population sequence; the board's memory-population rules dictate the exact slot order for a two-module 64GB configuration.
