OWC 512GB (2x256GB) DDR4 3200 CL22 ECC Registered RDIMM Kit for ASUS Pro WS WRX80E-SAGE SE WiFi

SKU CH-HRBE-XPNZ1

512 GB DDR4 3200 CL22 ECC registered RDIMM kit with two 256 GB 8Rx4 modules for the ASUS Pro WS WRX80E-SAGE SE WiFi workstation

Capacity 512GB (2 x 256GB)

  • ECC registered design protects data integrity in workstations and servers
  • 512 GB kit built from two 256 GB modules for high capacity
  • DDR4 3200 speed with CL22 latency for responsive performance
  • 2 V operation and 288-pin RDIMM form factor match platform requirements
  • Validated against Samsung, Hynix and Supermicro reference modules

System-Specific ECC RDIMM Kit

This 512GB kit contains two 256GB DDR4 3200 CL22 ECC Registered RDIMM modules built for the ASUS Pro WS WRX80E-SAGE SE WiFi workstation. It targets professionals who need maximum registered memory capacity for server-grade workloads and cannot use standard desktop RAM.

288-Pin Registered Platform Fit

Each module uses a 288-pin 1.2V 8Rx4 registered design that requires a WRX80 chipset motherboard supporting octal-rank ECC RDIMMs. The kit cannot be mixed with unbuffered or load-reduced DIMMs, so all slots must follow the same registered specification for stable operation.

JEDEC-Compliant Module Assurance

Modules are validated against Samsung M393ABG40M52-CAE, Hynix HMAT14JXSRB120N and HMAT14JXSRB122N, and Supermicro MEM-DR425MI-ER32 reference parts. OWC testing confirms JEDEC and RoHS compliance, giving installers confidence that the upgrade meets industry specifications without additional configuration.

Questions about this item

Will the CL22 latency become a bottleneck when the 512GB kit runs at 3200 MT/s for hours?

The modules are rated CL22 at 3200 MT/s; sustained workloads stay within that timing because the JEDEC-compliant DDR4 ICs maintain rated speed without throttling.

How much heat and power do two 256GB ECC Registered RDIMMs draw at 1.2V under continuous load?

Each 288-pin RDIMM operates at 1.2V; the octal-rank design spreads thermal load across 8Rx4 chips so the kit runs cool and quiet in a populated server chassis.

Does the ASUS Pro WS WRX80E-SAGE SE WiFi need any specific BIOS setting or matching DIMM population for this 512GB kit to post?

The kit is validated for that motherboard; populate the two 256GB RDIMMs in the recommended slots, enable ECC in BIOS, and the system will recognise the full 512GB at 3200 MT/s.
