Compatible DDR5 ECC UDIMM kit

This 64 GB kit contains four 16 GB unbuffered DDR5 ECC UDIMM modules rated at 5600 MT/s with CL46 latency. It is built for the ASRock Rack W680D4ID-2T/G5/X550 motherboard and runs at 1.1 V without a heat spreader.

DDR5 5600 interface limits

DDR5 5600 sets the maximum data rate and timing the modules can deliver on this platform. The unbuffered design means the memory controller drives each module directly, so total capacity and rank count are bound by the board's qualified vendor list.

Pre-order checks

Verify that your W680D4ID-2T/G5/X550 board lists 4 x 16 GB 1Rx8 ECC UDIMM at 5600 MT/s in its supported memory table. Confirm the four 288-pin slots are free and that the system BIOS is updated to the version that validates this kit.

Questions about this item

Should I pick the 4×16 GB kit or look for a different capacity for this board?

The kit supplies 64 GB total across four 16 GB modules, matching the four UDIMM slots on the ASRock Rack W680D4ID-2T/G5/X550.

What does the 5600 MT/s rating actually deliver once the modules are installed?

The memory runs at DDR5 5600 (PC5-44800) with CL46 latency at 1.10 V, giving the rated throughput the motherboard’s memory controller negotiates.

Does the 288-pin ECC UDIMM interface limit the speed or features on this platform?

The 288-pin DDR5 ECC unbuffered UDIMM format is the native interface for the board, so the kit operates at the specified 5600 MT/s without down-clocking.
