System-Specific 64GB DDR4 ECC Kit

This NEMIX RAM kit provides 64GB across two 32GB unbuffered UDIMM modules. It runs at DDR4 3200 with a CAS latency of CL22 and a voltage of 1.2V. The modules feature ECC error correction and a 2Rx8 rank configuration. They are validated for compatibility with ASRock Rack X570D4U series motherboards.

For ECC Server Builds Not General PCs

This memory suits administrators upgrading ASRock Rack X570D4U platforms that require DDR4 ECC unbuffered DIMMs. It is not for builders needing registered or load-reduced modules. It is also not for desktop users whose consumer motherboards lack ECC support or who prefer modules with heat spreaders.

DDR4 3200 CL22 288-Pin ECC UDIMM

The decisive specification is the DDR4 3200 CL22 288-pin ECC unbuffered UDIMM form factor. Only systems designed for this exact memory type will accept the kit. Verify your motherboard manual confirms support for 32GB unbuffered ECC modules at this speed and rank before purchase.

Questions about this item

Does DDR4 3200 (PC4 25600) run at 3200 MT/s on the X570D4U?

The kit is rated DDR4 3200 (PC4 25600). The X570D4U supports DDR4 3200, so the modules will operate at that speed when installed.

Will the 288-pin UDIMM modules fit the X570D4U's four DIMM slots?

Yes. The kit uses standard 288-pin DDR4 UDIMM form factor, which matches the four UDIMM slots on the X570D4U motherboard.

How do I install the two 32 GB sticks correctly, and what step is often missed?

Power off the system, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click. The step often missed is ensuring both clips fully lock on each stick.
