Eight green DDR5 RDIMM sticks in a row

NEMIX RAM

NEMIX RAM DDR5 256GB (8x32GB) 6400MHz CL52 1.1V ECC RDIMM Supermicro H13SRH

SKU CH-YEMM-GDGGM

256GB kit of eight 32GB DDR5 ECC registered DIMMs at 6400MHz CL52 1.1V for Supermicro H13SRH servers

  • Total capacity256 GB (8 × 32 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 256 GB total capacity lets you fill all eight slots with 32 GB modules
  • DDR5-6400 speed transfers data at PC5-51200 bandwidth for demanding server workloads
  • Registered ECC architecture buffers signals and corrects single-bit errors to protect data integrity
  • 10 V operation at CL52 latency matches the motherboard's exact voltage and timing requirements
  • 288-pin RDIMM form factor is the precise module type the Supermicro H13SRH memory controller expects

Exact-Match Server Kit

This NEMIX RAM kit delivers 256GB across eight 32GB DDR5 RDIMMs. Each module runs at 6400MHz with CL52 latency at 1.10V, using a 2Rx8 registered ECC design. The 288-pin form factor matches the Supermicro H13SRH motherboard requirements precisely.

Registered ECC Workloads

The registered architecture and ECC function suit virtualization hosts, database servers, and compute clusters that demand full-slot population and silent error correction. Systems requiring unbuffered UDIMMs, SODIMMs, or non-ECC memory cannot use this kit.

DDR5-6400 CL52 RDIMM

The 6400MHz CL52 2Rx8 registered specification is the single figure that determines compatibility with the H13SRH memory controller. Verify your motherboard manual supports this exact speed, rank, and voltage combination before installation.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SRH motherboard slots?

Yes, the kit uses the 288-pin Registered DDR5 form factor required by the H13SRH, so each module seats directly in the board's DDR5 DIMM slots.

What is the correct population order for the eight 32 GB modules on the H13SRH?

Follow the motherboard manual's approved DIMM population sequence; the kit's 2Rx8 registered design allows full capacity when every slot is filled in that order.

Do these registered ECC modules need any firmware updates or battery-backed maintenance later?

No firmware or battery maintenance is required; the ECC and registered architecture handles error correction in hardware for the life of the modules.
