Exact-match server kit

This NEMIX RAM kit delivers 256 GB across eight 32 GB DDR4 RDIMM modules rated at 2933 MHz (PC4-23400). Each stick is ECC registered, dual-rank 2Rx8, and timed at CL21 with a 1.20 V operating voltage. The 288-pin form factor matches the ASUS Pro WS C422-ACE workstation motherboard specification exactly.

Verify population rules

Before ordering, consult your motherboard manual for supported capacities per slot and the required DIMM installation sequence. The board demands registered RDIMMs, not unbuffered UDIMMs or SODIMMs, and population order affects whether all eight modules run at the rated 2933 MHz speed. Confirm the BIOS version and maximum supported capacity for your specific CPU configuration.

Suits fully populated ECC builds

Ideal for administrators expanding an ASUS Pro WS C422-ACE system to its maximum registered ECC capacity for virtualization, rendering, or scientific workloads that require error correction. Not suited for consumer desktops, laptops, or boards that accept only unbuffered non-ECC memory. Buyers needing lower capacities, different speeds, or unregistered modules should look elsewhere.

Questions about this item

Does the 256GB kit ship as eight 32GB modules or must I order each RDIMM separately?

The kit arrives as eight 32GB DDR4 2933MHz PC4-23400 2Rx8 1.2V CL21 288-pin ECC Registered RDIMMs in one package, so no additional modules are needed.

My board has eight slots — should I populate all eight with this 8x32GB kit or would a smaller kit leave room for later expansion?

The 8x32GB kit fills every slot on the ASUS Pro WS C422-ACE and delivers the full 256GB capacity the board supports; a smaller kit would leave empty slots but reduce total capacity.

Will the 2933MHz rating run at that speed once installed in the ASUS Pro WS C422-ACE, or does it drop to a lower JEDEC speed?

The modules are spec-matched to the ASUS Pro WS C422-ACE DDR4 2933MHz PC4-23400 profile, so the memory controller recognises the kit and operates it at the rated 2933MHz speed.
