System-specific DDR4 ECC kit

This NEMIX RAM kit provides 16GB of DDR4 3200 memory in a matched pair of 8GB modules. It is built for ASRock Rack motherboards including the X570D4U, X570D4U-2L2T and X570D4U-2L2T/BCM. The modules are unbuffered ECC UDIMMs rated at CL22 latency and 1.20V operation.

Check motherboard slot count and ECC support

Verify that your board has two free 288-pin DDR4 slots and that it enables ECC with unbuffered modules. Confirm the BIOS is updated to a version that recognises 1Rx8 density at 3200 MT/s. The kit runs at standard JEDEC voltage, so no manual voltage adjustment is required.

Suits ECC workstation and server builds

Builders assembling or upgrading the listed ASRock Rack platforms for data-integrity workloads will benefit from the validated compatibility. Systems that require registered or load-reduced DIMMs, or boards limited to non-ECC memory, cannot use this kit.
