16 GB DDR5 UDIMM for ASRock Rack

This 16 GB DDR5 5600 module uses a 1Rx8 organisation and runs at 1.1 V with CL46 latency. It is built as a non‑ECC unbuffered UDIMM on a 288‑pin PCB using major OEM chips from Samsung, Micron or Hynix. The part is validated for the ASRock Rack W880D4U-2L2T motherboard.

Who it suits and who it does not

System integrators upgrading the ASRock Rack W880D4U-2L2T will find a direct fit with this single 16 GB stick. Builders who need error‑correcting code memory or registered modules must choose a different part because this module is non‑ECC and unbuffered.

Deciding specification

The validated compatibility with the ASRock Rack W880D4U-2L2T motherboard is the single specification that confirms this module will operate correctly in the target system.
