ASRock Rack W880D4U-2L2T memory upgrade

This 64 GB kit contains two 32 GB DDR5 ECC unbuffered UDIMMs built for the ASRock Rack W880D4U-2L2T motherboard. Modules run at 5600 MT/s with CL46 latency and 1.1 V operation. The 2Rx8 organisation suits server and workstation workloads that require error correction.

Verify DDR5 ECC UDIMM support and slot count

Confirm the board accepts DDR5 ECC unbuffered UDIMMs and has at least two free 288-pin slots. The kit is validated for the W880D4U-2L2T; other platforms may not boot or may disable ECC. Check the system manual for population rules and maximum capacity per channel.

Low-voltage DDR5 thermals and power draw

Operating at 1.1 V keeps power draw modest for a 64 GB dual-rank kit. No heat spreaders are fitted, so airflow across the modules is the primary cooling path. In typical server chassis with directed airflow the memory runs quietly and stays within thermal limits.

Questions about this item

Does the kit include both 32 GB modules or do I need to buy a second stick?

The package contains a matched 64 GB kit with two 32 GB modules, so nothing else is required for a full 64 GB upgrade.

Should I choose the CL46 5600 MHz version or a different speed grade?

This kit is specified at DDR5 5600 with CL46 timing and 1.10 V; select it when your ASRock Rack W880D4U-2L2T calls for that exact speed and latency.

What does the 5600 MHz rating mean once the memory is installed in the W880D4U-2L2T?

The modules will run at the DDR5 5600 data rate with CL46 latency at 1.10 V, delivering the rated PC5-44800 bandwidth in that motherboard.
