Six green DDR5 server memory modules with gold contacts and black heat spreaders

NEMIX RAM

NEMIX RAM 144GB (6 x 24GB) DDR5 6400MHz PC5-51200 2Rx8 1.1V 288-PIN ECC RDIMM server RAM

SKU CH-YNQY-YPDPA

Six 24GB DDR5 modules deliver 144GB of registered ECC memory at 6400MHz with CL52 latency and 1.1V operation

  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx8
  • High capacity for demanding server workloads with 144GB total memory
  • Fast data throughput at DDR5 6400MHz PC5-51200 speed
  • Error-correcting code protects data integrity in critical applications
  • Registered design reduces electrical load for stable multi-module operation
  • Low 1.1V voltage improves efficiency in dense server configurations

Capacity and Purpose

This 144 GB kit ships as six 24 GB modules built for DDR5 6400MHz PC5-51200 registered ECC server platforms. The 2Rx8 organisation and 1.1 V operation target enterprise workloads that demand high density and error correction.

Sustained Load Behaviour

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded throughput. CAS latency of 52 cycles and the 1.1 V baseline keep power draw predictable when all slots are populated under extended compute cycles.

Build and Connectivity

Major OEM Samsung Micron Hynix components populate each 288-pin RDIMM for consistent signal quality across the kit. The registered interface requires a compatible server motherboard; standard desktop boards cannot accept these modules.

Questions about this item

Does the 1.1 V DDR5 6400 RDIMM kit produce noticeably more heat or fan noise when running continuously at full load?

Registered DDR5 modules at 1.1 V are designed for efficient server operation; the 2Rx8 organisation spreads workload across ranks, helping thermal performance during sustained all-day use.

What server platform must I already have to use this 288-pin ECC registered kit?

You need a DDR5-capable server motherboard with RDIMM slots that support 6400 MT/s PC5-51200 registered ECC memory and a CPU memory controller qualified for 2Rx8 modules.

Can I mix these 24 GB 2Rx8 modules with smaller single-rank DDR5 RDIMMs already in my server?

Mixing 2Rx8 dual-rank modules with single-rank DDR5 RDIMMs is possible only if the server firmware and memory controller explicitly support mixed-rank populations at 6400 MT/s.
