Compatible Memory for ASRock Rack W680D4U-2L2T/G5

This NEMIX RAM module is a 16GB DDR5 ECC unbuffered UDIMM built for the ASRock Rack W680D4U-2L2T/G5 motherboard. It runs at 5600MHz with a CAS latency of CL46 and operates at 1.1V. The single-rank 1Rx8 design uses major OEM chips from Samsung, Micron, or Hynix.

Suited for ECC UDIMM Slots.

This module fits servers and workstations that require DDR5 ECC unbuffered memory in a 288-pin form factor. It is not suitable for systems that need registered DIMMs, load-reduced DIMMs, or non-ECC consumer memory. Buyers without ECC UDIMM support should look at a different memory type.

The Deciding Spec Is ECC Unbuffered UDIMM at DDR5

The single specification that determines fit is the ECC unbuffered UDIMM interface running at DDR5 5600. If the motherboard calls for registered memory, a different voltage, or a non-ECC standard, this module will not work. Verify the board requires exactly this DDR5 ECC UDIMM format before ordering.

Questions about this item

Will the 1Rx8 ECC UDIMM need any firmware updates or periodic re-seating over its lifetime?

No firmware updates are required for this 16GB DDR5 5600 CL46 module. ECC corrects single-bit errors automatically, and the unbuffered design has no moving parts. Standard practice is to leave it installed unless a hardware fault appears.

What thermal or electrical limit appears first when the module runs at 5600 MT/s continuously?

The module operates at 1.10V with no heat spreader, so the DDR5 on-die thermal sensor and the motherboard's memory VRM are the first limits. Sustained full-speed operation stays within JEDEC thermal specifications for 1Rx8 UDIMMs.

How much power does the 16GB DDR5 5600 stick draw and does it produce audible noise under all-day load?

At 1.10V the 16GB module draws only a few watts, well within the 288-pin UDIMM slot budget. It has no fan or moving components, so it runs silently regardless of workload duration.
