System-Specific DDR4 ECC Kit

This 32 GB kit contains four 8 GB unbuffered UDIMM modules built for ASRock Rack B550D4 motherboards. It targets administrators and integrators who need validated ECC memory for server or workstation deployments.

Sustained-Load Behaviour

Modules are stress-tested under load at 3200 MT/s with CL22 timings and 1.2 V operation. The 1Rx8 organisation and major-brand Samsung, Micron or Hynix ICs maintain error correction without registered buffering during continuous workloads.

Deciding Specification

ECC unbuffered UDIMM format on 288-pin DDR4 is the single attribute that determines fit. Systems requiring registered DIMMs, non-ECC memory or a different pin count cannot use this kit.

商品問答

How much power do these 1.20V DDR4 modules draw under continuous load?

The kit runs at 1.20V, the standard DDR4 voltage, keeping power draw low during all-day operation.

Which motherboards must I already own for this 288-pin ECC UDIMM kit to work?

It is validated for ASRock Rack B550D4-4L, B550D4ID-2L2T, B550D4M, B550D4U and B550D4U-2T boards.

Will the CL22 3200MHz sticks run stably with slower DDR4 modules I keep installed?

The memory operates at DDR4 3200 with CL22 timing; the system will clock all installed modules to the lowest common speed.
