  • 288-pin RDIMM form factor verified for ASUS Pro WS C422-ACE workstation motherboard

Capacity and form factor

This 128 GB kit contains two 64 GB DDR4 RDIMMs built to the 288-pin registered standard. It targets administrators upgrading an ASUS Pro WS C422-ACE workstation that requires ECC registered memory.

Registered ECC limits

The registered buffer lets the memory controller drive every slot at full population without signal degradation, while ECC corrects single-bit errors before they corrupt data. UDIMM or SODIMM modules will not fit or function on this platform.

Rank and voltage match

Each module is a 2Rx4 device operating at 1.20 V with CL21 timing at 2933 MHz; the memory controller expects this exact rank structure and voltage to initialise at rated speed.

Questions about this item

Should I choose the 2x64GB kit or a different capacity for my ASUS Pro WS C422-ACE?

The 128GB kit provides two 64GB modules that match the board's DDR4-2933 registered ECC requirements and 2Rx4 rank structure for full-slot population.

What does the 2933MHz rating mean once installed in the workstation?

The modules run at DDR4-2933 (PC4-23400) with CL21 latency at 1.2V, delivering the exact speed and timing the motherboard's memory controller expects.

How does the 288-pin RDIMM interface affect compatibility and performance?

The 288-pin registered DIMM form factor is required by the ASUS Pro WS C422-ACE; the registered buffer offloads the memory controller so all slots operate at full rated capacity.
