Exact-match upgrade for ASUS Pro WS C422-ACE

This 32GB DDR4 2933MHz PC4-23400 2Rx8 ECC RDIMM is built for the ASUS Pro WS C422-ACE workstation motherboard. The registered architecture and CL21 timing match the board's memory controller requirements. It installs as a single 288-pin module operating at 1.20V. Builders needing a different form factor or non-ECC memory should look elsewhere.

Sustained-load behaviour with registered ECC

Registered buffering offloads the memory controller so every slot runs fully populated at rated speed without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs. The 1.20V operation keeps thermals stable under continuous load. Workloads that exceed single-module capacity or require unbuffered memory will not benefit from this design.

Deciding specification: 2Rx8 registered ECC at CL21

The 2Rx8 registered ECC organisation with CL21 latency is the single parameter the ASUS Pro WS C422-ACE memory controller expects for full-capacity recognition. A mismatched rank, voltage, or buffering type will cause the system to downclock, halve usable capacity, or fail to boot. Verify your manual's approved population order before purchasing.

Questions about this item

How much power does this 1.2V DDR4 module draw when the ASUS Pro WS C422-ACE workstation runs continuously?

At 1.20 V the module operates at standard DDR4 voltage, so power draw stays within the JEDEC spec for registered ECC RDIMMs and the motherboard's memory controller manages any throttling.

What motherboard slot and population rules must my ASUS Pro WS C422-ACE already have free to install this 288-pin RDIMM?

The board needs an empty 288-pin DDR4 RDIMM slot and you must follow the manual's population order; the module is a 2Rx8 registered DIMM that only fits registered-memory slots.

Will this CL21 registered ECC kit work alongside older DDR4 RDIMMs I keep in the other channels of my C422-ACE?

Mixed ranks and latencies are supported by the C422 chipset, but the system will run all modules at the slowest common speed and timings; populate per the manual for stability.
