Kit composition and target systems

This 128 GB kit contains four 32 GB DDR5 ECC unbuffered UDIMMs built for the ASRock Rack W880D4U-2L2T motherboard. It suits administrators who need maximum registered-style capacity on an unbuffered platform. Buyers who want registered or load-reduced modules cannot use this kit.

DDR5 5600 interface limits

The modules run at 5600 MT/s with a CL46 latency at 1.1 V. DDR5 5600 is the baseline JEDEC speed for this generation; systems that only support lower DDR5 data rates will not reach the rated frequency. Builders who need higher speeds or lower latencies must select a different specification.

Capacity headroom and constraints

Four dual-rank 32 GB modules fill every slot on a typical four-DIMM board, delivering 128 GB of ECC-protected memory for virtualization or large datasets. Workloads that exceed 128 GB or require registered signalling will run out of headroom with this kit.

Highlights

  • 128GB total capacity across four 32GB modules
  • DDR5 5600 speed with PC5-44800 bandwidth rating
  • ECC unbuffered UDIMM for data integrity in servers
  • CL46 latency at 1.1V operating voltage
  • 288-pin DDR5 form factor fits ASRock Rack W880D4U-2L2T

Questions about this item

Should I choose the 128GB kit or a smaller capacity for the ASRock Rack W880D4U-2L2T?

The 128GB kit provides four 32GB modules filling all slots on the ASRock Rack W880D4U-2L2T. Smaller capacities would leave slots empty and limit total memory.

What does the DDR5 5600 rating mean for real-world throughput on this board?

DDR5 5600 runs at 5600 MT/s, delivering up to 44800 MB/s of peak bandwidth per module when the motherboard operates at the rated speed.

Does the 288-pin ECC UDIMM interface limit speed or capacity on the W880D4U-2L2T?

The 288-pin ECC UDIMM format is the native interface for the W880D4U-2L2T, so the kit runs at the full 5600 MT/s without downclocking or capacity restrictions.
