Size 512GB 8X64GB

  • 512 GB total capacity for memory-intensive workloads using eight 64 GB modules
  • Registered ECC design corrects single-bit errors on the fly to prevent silent data corruption
  • DDR4-2933 speed at CL21 and 1.2 V matches the board's rated timing exactly
  • 288-pin RDIMM form factor fits the ASUS Pro WS C422-ACE memory slots precisely
  • 2Rx4 dual-rank organisation lets the controller address full density across all populated slots

512GB DDR4-2933 ECC RDIMM kit

This 512GB kit contains eight 64GB DDR4-2933 registered ECC RDIMMs built for the ASUS Pro WS C422-ACE workstation motherboard. Each module runs at 1.2V with CL21 timing and a 2Rx4 organisation. The registered design lets the memory controller drive a fully populated eight-slot configuration at the rated 2933 MT/s speed.

Registered ECC 2Rx4 at 2933 MT/s

The decisive specification is the combination of registered ECC, 2Rx4 rank structure and DDR4-2933 (PC4-23400) speed matching the motherboard's qualified memory list. A UDIMM, a different rank layout or an unsupported data rate will not be recognised at full capacity or will fail to post.

Suited for full-capacity C422 workstations.

This kit suits builders who need the maximum 512GB supported by the ASUS Pro WS C422-ACE with guaranteed stability from registered ECC. It is not for consumer desktop motherboards that only accept unbuffered non-ECC UDIMMs, nor for servers requiring a different voltage, rank configuration or form factor.

Questions about this item

Will the DDR4-2933 speed run at its rated frequency on the ASUS Pro WS C422-ACE?

Yes, the kit is spec-matched to the board's DDR4-2933 (PC4-23400) memory controller so all eight modules operate at the rated 2933 MT/s when installed per the motherboard's population rules.

Does the registered ECC RDIMM interface limit the number of modules I can populate?

The registered architecture offloads the memory controller, allowing all eight 64 GB DIMMs to run fully populated at full capacity while ECC corrects single-bit errors on the fly.

Will these 288-pin RDIMMs physically fit the ASUS Pro WS C422-ACE DIMM slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the slots required by the C422-ACE workstation motherboard; they are not UDIMM or SODIMM modules.
