Two green DDR5 RDIMM modules, no heat spreaders, 288-pin gold contacts

NEMIX RAM

NEMIX RAM 32GB 2x16GB DDR5 4800 CL40 ECC RDIMM SuperMicro memory upgrade

SKU CH-57RH-7EFVS

A 32 GB DDR5 ECC RDIMM kit (2 × 16 GB) at 4800 MT/s CL40 for SuperMicro servers

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • ECC protection prevents data corruption with registered DDR5 modules
  • 32GB dual-channel kit (2x16GB) expands server memory capacity
  • 4800MHz speed with CL40 latency optimises throughput
  • 1V operation reduces power draw in dense configurations
  • Validated for SuperMicro X13SEM and SYS-211E SuperServer platforms

Compatible SuperMicro DDR5 RDIMM Kit

This 32GB kit uses two 16GB DDR5 4800 RDIMM modules built for SuperMicro SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-T servers. It delivers registered ECC memory for enterprise workloads that require data integrity and platform validation.

Capacity and registered ECC headroom

The 32GB total capacity suits virtualization, database and file-service roles where error correction and signal buffering matter. Workloads that exceed 32GB or demand higher frequencies than DDR5 4800 will need additional DIMM slots or faster modules.

DDR5 4800 CL40 interface limits

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V on the 288-pin RDIMM interface. Systems that require speeds above 4800 MT/s, lower CAS latency, or non-registered DIMMs cannot use this kit.

Questions about this item

Will this DDR5 4800 ECC RDIMM kit work alongside existing DDR5 modules in my SuperMicro server?

Mixing memory kits is not recommended; for best stability populate all slots with identical 4800 CL40 1Rx8 registered modules so the memory controller runs a single timing set.

How can I verify the kit is running at DDR5 4800 CL40 with ECC active after installation?

Enter the BIOS or use a tool like CPU-Z to confirm the memory reports 4800 MT/s, CL40 latency, 1.10 V, and ECC enabled on each 16 GB module.

What is included in the package and do I need any extra parts to install it?

The box contains two 16 GB 288-pin DDR5 RDIMMs (32 GB total); no additional hardware is required beyond a compatible SuperMicro motherboard with free RDIMM slots.
