64GB DDR4 ECC UDIMM kit for ASRock Rack servers

This NEMIX RAM kit delivers 64GB of DDR4 3200 ECC unbuffered memory in four 16GB modules. It is built for system integrators and IT teams deploying ASRock Rack X570D4U motherboards where error-correcting code and validated compatibility are required. The 2Rx8 organisation and 1.2V operation match the platform specifications.

Suited for X570D4U builds needing maximum ECC

Administrators populating all four DIMM slots on X570D4U, X570D4U-2L2T or X570D4U-2L2T/BCM boards will reach the platform's supported memory ceiling with this kit. Builders using consumer motherboards without ECC support or systems limited to registered DIMMs should select a different product.

DDR4 3200 CL22 288-pin ECC UDIMM specification

The modules run at DDR4 3200 (PC4-25600) with CL22 latency, 2Rx8 rank structure and 1.2V voltage on a standard 288-pin UDIMM form factor. ECC is active and the modules are unbuffered, so the motherboard must support unbuffered ECC DDR4 at this speed and density.

Questions about this item

Does the 288-pin DDR4 UDIMM fit the ASRock Rack X570D4U motherboard?

Yes, the kit is built for the ASRock Rack X570D4U, X570D4U-2L2T and X570D4U-2L2T/BCM boards and uses the standard 288-pin DDR4 UDIMM form factor.

What is the correct slot order when installing the four 16 GB modules?

Populate all four DDR4 slots; the motherboard manual shows the exact channel order for a 4 x 16 GB 2Rx8 kit.

Will the ECC UDIMM modules need any firmware updates or battery replacements later?

No firmware or battery is required; the DDR4 ECC UDIMMs run at 1.2 V and are covered by a lifetime replacement warranty.
