System-Specific DDR4 ECC UDIMM

This 8 GB DDR4 module is built for ASRock Rack X570D4U series motherboards. It targets administrators and integrators who need validated ECC memory for server or workstation deployments.

Sustained-load behaviour

The module operates at 1.20 V with CL22 latency and 1Rx8 organisation, delivering steady throughput under continuous workloads without a heat spreader. ECC correction maintains data integrity during extended operation in compatible ASRock platforms.

Deciding specification

ECC unbuffered UDIMM format at DDR4 3200 (PC4-25600) is the single factor that determines fit; only systems accepting this exact type and speed will recognise and use the module correctly.

Questions about this item

How much heat and power does the 1.20V DDR4 3200 module draw when the server runs continuously?

At 1.20 volts the UDIMM stays cool without a spreader and draws only the standard DDR4 3200 power envelope, so sustained loads add minimal heat to the chassis.

What must the motherboard provide for this 288-pin ECC UDIMM to function?

The board needs a DDR4 slot that supports 3200 MT/s ECC unbuffered memory and the ASRock X570D4U chipset to match the validated configuration.

Will the CL22 1Rx8 stick work alongside older DDR4 modules I already have installed?

It will run at the speed and latency of the slowest module present; mixing ranks or CL values is possible but may reduce overall throughput.
