NEMIX RAM

NEMIX RAM 32GB DDR5 5600 CL46 1.1V 2Rx8 288-Pin UDIMM for ASRock Rack W680D4U-2L2T/G5 memory upgrade

SKU CH-TFFH-7H46Y

A 32 GB DDR5 module running at 5600 MT/s with CL46 latency and 1.1 V operation, built for the ASRock Rack W680D4U-2L2T/G5 motherboard

  • Total capacity32 GB
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Buffer typeUnbuffered
  • Rated voltage1.1 V
  • 32 GB capacity adds headroom for heavy workloads
  • DDR5 5600 speed moves data faster than slower modules

Compatible DDR5 upgrade for ASRock Rack

This 32 GB DDR5 UDIMM is validated for the ASRock Rack W680D4U-2L2T/G5 motherboard. It targets system builders and IT professionals who need a straightforward capacity increase for that specific platform. The single-module design leaves additional slots free for future expansion.

Sustained operation at 5600 MT/s with CL46 latency

The module runs at the standard DDR5 5600 speed with a CAS latency of 46 cycles. Its 1.10 V operating voltage aligns with the JEDEC baseline, helping to limit heat during long workloads. The 2Rx8 organisation supports efficient data throughput for multi-threaded server and workstation tasks.

Unbuffered non-ECC build

The stick uses major-brand Samsung, Micron or Hynix ICs without a heat spreader, keeping the profile low for dense chassis. As an unbuffered non-ECC UDIMM it plugs directly into the board's 288-pin slots without registration overhead. The simple pin-out ensures quick installation and reliable daily seating.

Questions about this item

How much heat or power will the 1.1 V DDR5 module add when the system runs continuously?

The module operates at 1.1 V with no heat spreader, so it draws standard DDR5 power and relies on case airflow for cooling during all-day use.

What must the motherboard provide for this 288-pin UDIMM to function?

The board needs a DDR5 UDIMM slot supporting 5600 MT/s, 1.1 V operation and non-ECC unbuffered memory.

Will this CL46 2Rx8 stick work alongside slower DDR5 modules already installed?

Yes, the motherboard will run all populated slots at the speed and timings of the slowest module present.
