1TB DDR4-3200 ECC RDIMM kit

This NEMIX RAM kit delivers 1TB of registered DDR4 memory across eight 128GB modules rated at 3200 MT/s with CL22 latency. ECC and registered buffering provide the error correction and signal integrity required for stable server and workstation operation. The modules run at 1.2V and use a 288-pin RDIMM form factor.

Suited for ASUS Pro WS WRX80E-SAGE SE WiFi builds

The kit is validated for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard, making it a direct fit for that platform. Systems needing unbuffered UDIMMs, non-ECC memory, lower capacities or different pin layouts should consider other options. Builders targeting consumer desktop chipsets or laptop SO-DIMM slots cannot use these modules.

Sustained load behaviour

Registered buffering and ECC maintain data integrity during continuous multi-threaded workloads such as virtualization, database serving or render farms. The 4Rx4 organisation and major OEM DRAM from Samsung, Micron or Hynix support consistent throughput without the error accumulation seen in non-ECC configurations. Modules operate without heat spreaders, relying on chassis airflow for thermal management.

Questions about this item

What motherboard is required for this 1TB DDR4 3200 ECC RDIMM kit to function?

The kit is built for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard and follows its memory population rules.

Can I keep existing RDIMMs installed while adding these 128GB 4Rx4 modules?

All slots should use identical 4Rx4 modules at 1.2V CL22 to maintain stability; mixing ranks or speeds is not supported by the platform.

How do I confirm the 3200MT/s speed and ECC function are active after installation?

Enter the BIOS and verify the memory reports DDR4 3200, CL22, 1.2V and ECC enabled for all eight modules.
