Exact-Match Kit for ASUS Pro WS C422-ACE

This 256GB kit comprises four 64GB DDR4-2933 Registered ECC RDIMMs built to the precise rank, voltage and timing the board expects. It is intended for workstation and server builders who need the full 256GB capacity recognised at rated speed without manual tuning.

Registered ECC Headroom and Limits

The registered architecture offloads the memory controller so all four slots run fully populated at 2933MHz, while ECC corrects single-bit errors before they corrupt data. The kit stops at 256GB; buyers who want more storage or higher frequencies must choose a different platform.

288-Pin RDIMM Form Factor Decides Fit

These modules use the 288-pin Registered DIMM form factor required by the ASUS Pro WS C422-ACE. They will not fit UDIMM or SODIMM slots, so verify the board's DIMM population rules before purchase.
