Eight green DDR4 RDIMM modules in static bags

NEMIX RAM

NEMIX RAM 512GB 8x64GB DDR4 2933MHz ECC Registered RDIMM memory upgrade

SKU CH-7RCT-SFSHG

Eight 64 GB DDR4 2933 MHz ECC Registered RDIMMs provide 512 GB of server-grade memory with CL21 latency and 1.2 V operation for the ASUS WS C621E SAGE workstation motherboard

  • Total capacity512 GB (8 × 64 GB)
  • Rated speedDDR4 2933 (PC4 23400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeRegistered

Size 512GB 8X64GB

  • 512 GB kit enables maximum server capacity with eight 64 GB modules
  • ECC and registered design correct single-bit errors and stabilise fully populated slots
  • DDR4-2933 CL21 timing matches the ASUS WS C621E SAGE controller exactly
  • 20 V low-voltage operation reduces power draw at full 512 GB load
  • 288-pin RDIMM form factor fits the workstation motherboard without adapters

Exact-match server kit

This NEMIX RAM kit delivers 512GB across eight 64GB DDR4 2933MHz registered ECC RDIMMs. It is built for the ASUS WS C621E SAGE workstation motherboard and matches the board's required 288-pin RDIMM form factor, 1.2V operation and CL21 timing.

Upgrade from partial or mismatched sets

The 8x64GB 2Rx4 configuration satisfies the motherboard's full-population rules so every slot runs at rated speed. It replaces smaller-capacity kits or mixed-rank modules that limit total memory or force downclocking, and the registered buffer offloads the memory controller for stable operation under sustained load.

Suits workstation builders needing maximum

Buyers who need the full 512GB supported by this platform get a single matched kit with lifetime replacement coverage. Builders who require a different DIMM count, lower total capacity or non-ECC unbuffered memory should look at other configurations.

Questions about this item

Will the 288-pin RDIMM modules fit the ASUS WS C621E SAGE motherboard slots?

Yes. The kit uses the 288-pin Registered DIMM form factor that the C621E SAGE requires; it is not a UDIMM or SODIMM, so it seats directly in the board's DDR4 slots.

What population order should I follow when installing all eight 64GB sticks?

Consult the ASUS WS C621E SAGE manual for the approved DIMM population sequence; the board's memory-controller rules dictate which of the eight slots must be filled first for full 512GB recognition.

Do these Registered ECC modules need any periodic maintenance or replacement?

No routine maintenance is required; the ECC function corrects single-bit errors automatically, and the modules are covered by a lifetime replacement warranty if a hardware fault ever develops.
