Eight green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 256GB (8x32GB) DDR5 4800 CL40 1.1V ECC RDIMM memory upgrade

SKU CH-B4NF-XX3QK

Eight 32 GB DDR5 modules deliver 256 GB of registered ECC memory at 4800 MT/s with CL40 latency for Supermicro FatTwin and SuperServer systems

  • Capacity256GB (8 x 32GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 256 GB kit (8 × 32 GB) maximises server capacity
  • DDR5 4800 MT/s (PC5-38400) delivers high throughput
  • ECC registered RDIMM protects data integrity
  • 10 V operation reduces power draw
  • Validated for Supermicro FatTwin SYS-F521E3-RTB and SYS-F511E2-RT

Compatible SuperMicro Server Memory Kit

This 256GB kit contains eight 32GB DDR5 RDIMM modules built for SuperMicro FatTwin and SuperServer systems including SYS-F521E3-RTB, SYS-F511E2-RT and X13SEFR-A. ECC registered operation protects data integrity in mission-critical workloads.

Registered 288-Pin Design Without Heat Spreaders

Each module uses a 288-pin DDR5 RDIMM form factor with 1Rx4 organisation and no heat spreader, allowing dense population in 1U and 2U chassis where vertical clearance is tight. Registered buffering reduces electrical load on the memory controller for stable operation at full capacity.

Low-Voltage DDR5 At 4800 MT/s CL40

The kit runs at 1.10V with a CAS latency of 40, delivering PC5-38400 bandwidth while keeping power draw and thermals modest in typical server deployments. ECC correction and registered signalling maintain reliability under sustained load without active cooling on the modules themselves.
