Sixteen green DDR5 RDIMM modules with silver heat spreaders and gold contacts

NEMIX RAM

NEMIX RAM 2TB 16x128GB DDR5 6400 ECC RDIMM 2Rx4 1.1V

SKU CH-1YRC-DJRJS

A 2TB registered DDR5 server memory kit with sixteen 128GB modules at 6400MHz, ECC, 2Rx4 and 1.1V

  • Total capacity2 TB (16 × 128 GB)
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Massive 2 TB capacity from 16 modules of 128 GB each
  • DDR5 6400 speed rated at PC5-51200 for high throughput
  • ECC registered design detects and corrects data errors automatically
  • Low 1.1 V operation reduces power draw per module
  • Dual-rank 2Rx4 organisation maximises density per DIMM slot

Server-grade DDR5 capacity

This kit delivers 2TB of DDR5 memory across 16 registered DIMMs, each rated at 128GB. ECC and registered signalling protect data integrity in multi-socket servers and workstations that demand maximum capacity per channel.

288-pin registered DIMM installation

The modules use the standard 288-pin DDR5 RDIMM form factor and operate at 1.1V. They require a platform with DDR5 RDIMM slots and registered memory support; they will not function in desktop or laptop SO-DIMM sockets or in systems that only accept unbuffered DIMMs.

Sustained throughput at 6400 MT/s

Rated at DDR5 6400 (PC5-51200) with a CAS latency of 52, the kit maintains its specified transfer rate under continuous server workloads. The 2Rx4 organisation and major OEM DRAM chips provide stable operation during extended compute or virtualisation tasks.

Questions about this item

What CAS latency limit applies to this 6400 DDR5 kit under sustained load?

The kit operates at a fixed CAS latency of 52 cycles at DDR5 6400 speeds.

How much heat or power does the 1.1 V registered design generate during all-day server use?

Each module runs at 1.1 V; registered buffering and ECC add minimal overhead compared with unbuffered DIMMs.

Which motherboard slot and chipset combination is required for these 288-pin RDIMMs to function?

A server board with DDR5 288-pin RDIMM slots and registered-ECC support is required; consumer desktop boards will not work.
