NEMIX RAM

NEMIX RAM 1.5TB (12x128GB) DDR5 4800 PC5-38400 4Rx4 CL40 288-Pin ECC RDIMM Cisco UCS C220 M7

SKU CH-YH1Y-CRCT4

A 1.5 TB DDR5 registered ECC kit of twelve 128 GB modules running at 4800 MT/s with CL40 latency, built for Cisco UCS C220 M7 rack servers

  • Total capacity1.5 TB (12 × 128 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 5 TB total capacity for large-scale workloads with 12 modules of 128 GB each
  • DDR5 4800 MT/s speed rated at PC5-38400 for high-throughput server tasks

1.5 TB DDR5 RDIMM kit for Cisco UCS C220 M7

This 12-module kit delivers 1.5 TB of registered ECC DDR5 memory built for the Cisco UCS C220 M7 rack server. It targets IT teams that need maximum capacity per channel for virtualisation, databases or high-performance computing workloads. Each module runs at 4800 MT/s with CL40 latency and 1.1 V operation.

4Rx4 registered modules with major OEM chips

Twelve 128 GB 288-pin RDIMMs use 4Rx4 organisation and chips sourced from Samsung Micron or Hynix to ensure signal integrity at full load. The registered buffer reduces electrical load on the server memory controller allowing all twelve slots to be populated without timing compromises. No heat spreaders are fitted so airflow in dense chassis remains unobstructed.

1.1 V DDR5 lowers power draw under load

Operating at 1.1 V the kit draws less power per gigabyte than previous DDR generations while sustaining 4800 MT/s throughput. Registered buffering and on-die ECC maintain data integrity during sustained compute tasks without adding audible noise since the modules are passive. Thermal output scales with total capacity so adequate server airflow is required.
