NEMIX RAM DDR4 2933 128GB 4x32GB CL21 ECC RDIMM ASUS Pro WS C422-ACE memory upgrade

Exact-match 128 GB DDR4-2933 kit

This 128 GB kit contains four 32 GB DDR4-2933 (PC4-23400) Registered ECC RDIMMs built to the exact rank, voltage and timing the ASUS Pro WS C422-ACE motherboard expects. The modules are CL21, 1.20 V, 2Rx8, 288-pin and use major-brand Samsung, Micron or Hynix DRAM so the memory controller recognises the full capacity at rated speed.

Build fit: four-slot population

Each stick is a 288-pin Registered RDIMM, not a UDIMM or SODIMM, so it fits the board's required form factor and population rules when all four slots are filled. Registered buffering offloads the memory controller, allowing stable operation at full capacity, while on-die ECC corrects single-bit errors before they cause silent data corruption or unplanned reboots.

Suited for ASUS Pro WS C422-ACE upgrades

This kit is intended for owners of that specific workstation board who need the full 128 GB validated configuration. Builders using a different motherboard, or who need unbuffered UDIMMs, SODIMMs, a different speed grade, or a smaller capacity, should verify their manual before buying.
