128 GB DDR5 ECC UDIMM kit for ASRock Rack W680D4ID

This 128 GB kit contains four 32 GB DDR5 5600 modules built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard. ECC unbuffered operation protects data integrity in server and workstation workloads. The 2Rx8 organisation and CL46 latency suit multi-threaded applications that need large memory capacity.

1.1 V operation with no heat spreader

Each module runs at 1.10 V, keeping power draw low in densely populated slots. The absence of a heat spreader reduces height, allowing tight spacing in 1U or 2U chassis where airflow is directed across bare PCBs. Passive cooling from chassis fans is sufficient for typical sustained loads.

288-pin DDR5 form factor fills four UDIMM slots

The kit occupies all four UDIMM slots on the target board, delivering the maximum supported capacity without mixing module sizes. No registered or buffered memory is required, simplifying BIOS configuration. Builders needing more than 128 GB must choose a platform with additional memory channels.
