Two green DDR5 RDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 256GB (2x128GB) DDR5 6400MHz ECC RDIMM 4Rx4 1.1V Supermicro X14SBI-F memory upgrade

SKU CH-X2XG-6VVDS

Adds 256 GB of DDR5 ECC registered memory at 6400 MHz for Supermicro X14SBI-F servers

  • Capacity256GB (2 x 128GB)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • Compatible SystemSupermicro
  • 256 GB total capacity for large server workloads
  • 6400 MHz DDR5 speed with PC5-51200 bandwidth
  • ECC registered RDIMM with 4Rx4 organisation for data integrity

256GB DDR5 ECC RDIMM Kit

This 256GB kit contains two 128GB DDR5 registered DIMMs built for the Supermicro X14SBI-F platform. Error-correcting code and registered signalling protect data integrity in server and workstation workloads. The modules run at 6400MHz with a CL52 latency at 1.1V. IT professionals handling mission-critical environments are the target audience.

Fits Supermicro X14SBI-F DIMM Slots

The 288-pin RDIMMs install directly into the board’s DDR5 slots without adapters or cables. Registered buffering reduces electrical load on the memory controller, freeing headroom for high-density population. No heat spreaders are fitted, so airflow in the chassis must be sufficient for the bare modules. Builders needing unbuffered or non-ECC memory cannot use this kit.

Replaces Lower-Capacity DDR5 RDIMMs

Swapping smaller registered modules for this 2x128GB kit doubles or quadruples usable memory per channel, which benefits virtualisation, large datasets and AI inference workloads. The upgrade is worth it when the application hits capacity limits on the existing configuration. Systems requiring higher frequencies or lower latencies than 6400MHz CL52 will not gain from this change.

Questions sur cet article

Will the 6400 MHz speed hold under continuous server workloads?

The kit is rated at 6400 MHz PC5-51200 with CL52 latency; sustained throughput depends on the Supermicro X14SBI-F memory controller and cooling.

How much heat and power do two 128 GB modules draw at 1.1 V all day?

Each module runs at 1.10 V without a heat spreader; total power scales with load and the platform’s voltage regulation.

What motherboard feature is required to use 4Rx4 registered ECC DIMMs?

The Supermicro X14SBI-F must support DDR5 288-pin RDIMM slots with registered ECC and 4Rx4 addressing.
