48 GB DDR5 ECC UDIMM for ASRock Rack W680D4ID

This 48 GB DDR5 5600 module is built as a single unbuffered ECC UDIMM for the ASRock Rack W680D4ID-2T/G5/X550 motherboard. It targets system builders and IT staff who need validated, error-correcting memory for workstation or server workloads on that specific platform.

Major-brand DRAM at 1.1 V with 288-pin DDR5 layout

The stick uses major OEM Samsung, Micron or Hynix chips in a 2Rx8 organisation and runs at 1.10 V with CL46 latency. No heat spreader is fitted, so airflow across the bare PCB is the only cooling path; the standard 288-pin DDR5 keying ensures it seats only in a DDR5 UDIMM slot.

Check DDR5 UDIMM slot count

Verify that your W680D4ID-2T/G5/X550 board has a free DDR5 UDIMM slot and that its BIOS enables ECC on unbuffered modules. This kit is a single 48 GB rank pair; buyers who need more total capacity or a matched multi-module set must look elsewhere.
