NEMIX RAM 48GB DDR5 5600 CL46 2Rx8 1.1V 288-Pin UDIMM for ASRock Rack W880D4U-2L2T memory upgrade

48GB DDR5 module for ASRock Rack workstations

This 48GB DDR5 UDIMM is built for the ASRock Rack W880D4U-2L2T motherboard. It targets administrators and integrators who need to expand system memory on that specific platform. The single-module design simplifies slot population in dense server chassis. Non-ECC unbuffered operation matches the board's supported memory type.

DDR5 5600 speed and CL46 timing limits

The module runs at DDR5 5600 (PC5-44800) with a CAS latency of 46 cycles. That frequency ceiling is set by the memory controller on the compatible platform, so the kit cannot exceed 5600 MT/s. CL46 reflects the standard JEDEC timing at this data rate, meaning latency is fixed by the specification rather than a tighter bin. Builders who need lower latency or higher bandwidth must choose a different platform.

Single 48GB rank configuration and voltage headroom

The 2Rx8 organization delivers 48GB in one 288-pin DIMM at 1.1V, leaving other slots free for further expansion up to the motherboard's maximum capacity. Systems that require ECC error correction or registered buffering cannot use this module. Workloads demanding more than 48GB per slot will need higher-density parts when they become qualified for this board.
