512GB DDR4 3200 ECC RDIMM kit

This NEMIX RAM kit delivers 512GB across four 128GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. ECC and registered buffering protect data integrity in demanding server and workstation workloads. The modules run at 1.2V and use a standard 288-pin RDIMM form factor for compatible platforms.

For ASUS WRX80E-SAGE SE WiFi builds

This memory kit is validated for the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard and suits administrators scaling memory capacity for virtualization, databases or render farms. Buyers needing unbuffered UDIMMs, lower-density modules or non-ECC memory for consumer desktops should look at other product lines instead.

4Rx4 quad-rank organization

Each 128GB module uses a 4Rx4 configuration, so the memory controller must support quad-rank registered DIMMs at this density. Verify that your platform’s BIOS and chipset explicitly allow 4Rx4 RDIMMs before purchase, as some server boards limit rank count per channel.

Questions about this item

How do I confirm the kit runs at 3200 MT/s with CL22 after installation?

Enter the system BIOS or UEFI and verify the memory frequency shows 3200 and the CAS latency reads 22; the registered ECC modules will also report 4Rx4 organisation.

What exactly ships in the box and is anything else required?

The package contains four 128 GB 288-pin DDR4 RDIMM modules totalling 512 GB; no additional cables, brackets or cooling parts are included or needed.

Why choose the 4Rx4 512 GB kit instead of a lower-capacity option?

The 4Rx4 organisation and 512 GB total capacity are required to fully populate the ASUS Pro WS WRX80E-SAGE SE WiFi motherboard's registered ECC memory channels for maximum supported density.
