512GB DDR5 ECC RDIMM kit

This 512GB kit contains four 128GB DDR5 5600 modules built for the ASRock WRX90 WS EVO motherboard. Each stick is a registered 4Rx4 ECC RDIMM running at 1.10V with CL46 latency. It targets workstation and server builders who need maximum registered capacity on this platform.

Verify WRX90 WS EVO slot population rules

Before ordering, confirm that your ASRock WRX90 WS EVO motherboard supports four 128GB 4Rx4 registered DIMMs at the rated 5600 speed. Check the board manual for approved rank-per-channel limits and any BIOS version required for 512GB total capacity. Ensure the CPU installed also supports this memory configuration.

Registered ECC stability under sustained load

The registered buffer and on-die ECC correct single-bit errors in real time while the modules run continuously at 5600 MT/s and 1.10V. Because the kit uses major OEM DRAM chips validated for server workloads, signal integrity remains consistent during extended compute passes without the voltage drift seen in unbuffered consumer modules.

Highlights

  • 512 GB total capacity from four 128 GB modules
  • DDR5 5600 speed rated at PC5-44800 bandwidth
  • ECC registered design protects data integrity under load
  • 1 V operation reduces power draw per module
  • Validated for ASRock WRX90 WS EVO motherboard compatibility
