Eight green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM 512GB (8x64GB) DDR5 6400MHz ECC RDIMM memory upgrade

SKU CH-8MRJ-XAX9S

Eight 64 GB DDR5 ECC registered modules at 6400 MHz CL52 and 1.1 V for Supermicro X14SBI-F servers

  • Total capacity512 GB (8 × 64 GB)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • Memory rank4Rx4
  • 512GB total capacity scales memory-intensive workloads
  • 6400MHz DDR5 speed accelerates data throughput
  • ECC registered design protects data integrity
  • 1V operation reduces power consumption
  • 8-module kit simplifies Supermicro X14SBI-F deployment

Target Platform

This 512GB DDR5 ECC RDIMM kit is built for the Supermicro X14SBI-F server motherboard. It contains eight 64GB registered modules that operate at 1.1V and carry the PC5-51200 designation for enterprise workloads.

Decisive Specification

The kit runs at DDR5 6400MHz with CL52 latency in a 4Rx4 organisation across 288 pins. That exact speed, rank and voltage combination is what the X14SBI-F memory controller expects for full population without down-clocking.

Fit and Limits

IT teams running virtualisation, AI training or large databases on this specific Supermicro platform will hit the board's maximum supported capacity with one kit. Buyers who need a different form factor, non-ECC modules or a lower total capacity should look at other configurations.

Questions about this item

What does the 6400 MHz speed deliver when installed in a Supermicro X14SBI-F server?

The modules run at 6400 MHz PC5-51200 with CL52 latency, providing the rated bandwidth for DDR5 registered DIMM slots on that platform.

How does the DDR5 RDIMM interface and ECC registration affect usable capacity and error handling?

Each 64 GB stick is a 4Rx4 registered ECC module; the register buffers commands and ECC corrects single-bit errors, so all 512 GB are addressable by the memory controller.

What physical slot and power requirements must the motherboard meet for these 288-pin DIMMs?

They need eight DDR5 288-pin RDIMM slots and operate at 1.10 V; the board must support registered memory and supply that voltage.
