Kit details

This 32 GB kit contains two 16 GB DDR4 3200 modules rated at CL22 and 1.2 V. Each stick is a 288-pin ECC unbuffered UDIMM built with 2Rx8 organisation using Samsung, Micron or Hynix chips.

Upgrade path

The kit replaces slower DDR4 memory or smaller capacity kits in compatible ASRock Rack motherboards such as the X570D4U series. The jump is worthwhile when ECC data integrity and 32 GB total capacity are required for server or workstation workloads.

Ideal users

Suits administrators building or expanding ASRock Rack X570D4U platforms that need validated ECC unbuffered memory. Not for systems that require registered DIMMs, non-ECC modules, DDR5 slots or capacities beyond 32 GB.

Questions about this item

Does this kit need a 288-pin DDR4 slot and 1.2 V power on the ASRock Rack X570D4U-2L2T/BCM?

Yes, each module is a 288-pin DDR4 UDIMM rated for 1.2 V operation.

What is the correct way to seat the two 16 GB sticks so the board runs in dual-channel mode?

Insert both modules into the same-coloured DIMM slots indicated in the motherboard manual until the retention clips click.

When should the ECC UDIMMs be replaced if they start causing corrected memory errors?

Replace the kit when the system logs show a rising count of corrected ECC events or the modules fail a full memory test.
