Four green DDR4 ECC RDIMM modules with gold contacts

OWC

OWC 1TB (4×256GB) DDR4 3200 CL22 ECC Registered RDIMM Kit for ASRock WRX80 Creator R2.0

SKU CH-VJFH-XWTKQ

A 1 TB DDR4 ECC Registered RDIMM kit of four 256 GB modules at 3200 CL22 for the ASRock WRX80 Creator R2.0 workstation board

Capacity 1TB (4 x 256GB)

  • 1TB total capacity with four 256GB modules
  • DDR4 3200 speed for high-throughput workloads
  • ECC registered design detects and corrects data errors
  • CL22 latency at 1.2V for efficient operation
  • Validated for ASRock WRX80 Creator R2.0 workstations

Purpose-Built Workstation Memory

This 1TB kit contains four 256GB DDR4 3200 ECC Registered RDIMMs validated for the ASRock WRX80 Creator R2.0 platform. It is designed for workstation and server workloads that require registered memory with error correction. The modules will not operate in standard desktop computers or alongside unbuffered or load-reduced DIMMs.

Thermals Power and Noise

Each module runs at 1.2V under JEDEC-standard DDR4 specifications with CL22 latency. Registered buffering and ECC circuitry add minimal overhead while maintaining signal integrity across all four slots. No active cooling is included or specified for these DIMMs.

Compatibility and Validation

The kit is cross-referenced against Samsung M393ABG40M52-CAE, Hynix HMAT14JXSRB120N and HMAT14JXSRB122N, and Supermicro MEM-DR425MI-ER32 part numbers. OWC testing ensures the modules meet JEDEC and ROHS requirements for the target motherboard. Mixing with other memory types is not supported.

Questions about this item

How do I install the 288-pin RDIMMs on the ASRock WRX80 Creator R2.0 and which step is often missed?

Power off, open the case, align each module’s notch with the slot key, press down until both retention clips click, then verify all four are detected in BIOS before closing the chassis.

What maintenance will the ECC registered kit need over its service life?

No routine maintenance is required; keep the system’s air filters clean so the modules stay within their 1.2 V operating envelope.

What limit appears first when the 3200 CL22 8Rx4 modules run sustained workloads?

The memory controller’s thermal throttle point is reached before the DDR4 JEDEC voltage ceiling, so adequate case airflow becomes the limiting factor.
