ASRock Rack X570D4U ECC UDIMM Upgrade

This NEMIX RAM module adds 16 GB of DDR4 3200 ECC unbuffered memory to compatible ASRock Rack motherboards. It runs at 1.2 V with CL22 latency and a 2Rx8 organisation. The 288-pin UDIMM fits standard DDR4 slots without a heat spreader.

For servers needing ECC integrity.

Builders running ASRock Rack X570D4U, X570D4U-2L2T or X570D4U-2L2T/BCM boards gain error-correcting protection for data-critical workloads. Systems that do not support ECC unbuffered DDR4 cannot use this module. Buyers who need registered or load-reduced DIMMs should look elsewhere.

DDR4 3200 CL22 ECC unbuffered 2Rx8 at 1.2 V

The single decisive specification is the DDR4 3200 ECC unbuffered UDIMM profile with CL22 timing and 2Rx8 rank structure. Verify that your motherboard qualifies this exact combination before purchase.

Questions about this item

Will the 3200 speed run at that rate in my ASRock X570D4U?

The module is rated DDR4 3200 PC4-25600; the X570D4U supports that speed natively so it will operate at 3200 MHz without manual tuning.

Does the ECC unbuffered design work with standard desktop boards?

This is a 288-pin DDR4 ECC UDIMM; it requires a motherboard that explicitly supports unbuffered ECC — the ASRock X570D4U and listed variants do, typical consumer boards do not.

Will the 288-pin stick fit in a standard DDR4 DIMM slot?

Yes, it uses the standard 288-pin DDR4 UDIMM form factor and 1.2 V operation, so it installs in any DDR4 UDIMM slot that accepts unbuffered ECC modules.
