NEMIX RAM DDR5-6400 ECC Registered RDIMM 384GB (6x64GB) CL52 1.1V 2Rx4 Supermicro H13DSH

SKU CH-DT95-ANCMJ

Six 64 GB DDR5 ECC registered RDIMMs deliver 384 GB at 6400 MHz CL52 1.1 V for the Supermicro H13DSH motherboard

  • Total capacity384 GB (6 × 64 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 384 GB total capacity lets you fully populate the Supermicro H13DSH
  • DDR5-6400 speed with CL52 timing delivers rated throughput at 1.1 V

  • 2Rx4 dual-rank organisation maximises density across all six 64 GB modules
  • 288-pin RDIMM form factor matches the motherboard slot requirement exactly

Exact-match 384 GB DDR5-6400 kit

This registered ECC RDIMM kit delivers 384 GB across six 64 GB modules. It runs at DDR5-6400 with CL52 latency at 1.1 V. The 2Rx4 organization matches the Supermicro H13DSH memory controller requirements. System builders targeting maximum supported capacity on this platform use this kit.

Upgrade from partial populations

Servers running with fewer DIMMs or lower-capacity modules gain full-channel bandwidth and ECC protection across every slot. The jump is worth it when workloads need the full 384 GB address space and registered buffering to keep all channels stable at rated speed. Systems limited to lower densities or UDIMM slots cannot use this configuration.

Capacity headroom for dense workloads

The 384 GB total handles large in-memory databases, virtualization hosts, and HPC datasets that exceed smaller kits. Registered architecture keeps all six slots populated at full frequency without signal degradation. Workloads needing more than 384 GB or a different form factor require a platform change.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the Supermicro H13DSH motherboard slots?

Yes, the kit uses the exact 288-pin Registered RDIMM form factor the H13DSH requires, not UDIMM or SODIMM, so each module seats directly in the board's DDR5 DIMM slots.

What is the correct installation order for the six 64 GB modules on the H13DSH?

Consult the motherboard manual for the approved population sequence; the board's memory-controller rules dictate which slots must be filled first to recognise the full 384 GB at DDR5-6400.

Do these Registered ECC modules need any firmware updates or battery replacements over time?

No, the RDIMMs have no onboard firmware or battery; ECC correction and registered buffering are handled by the memory controller, so the modules themselves require no ongoing maintenance.
