32GB DDR4-2666 ECC kit for ASUS Pro WS C246-ACE

This NEMIX RAM kit supplies 32GB in four 8GB unbuffered ECC UDIMMs. The modules run at DDR4-2666 with CL19 latency at 1.2V and a 1Rx8 rank structure. They match the exact electrical and timing profile the ASUS Pro WS C246-ACE workstation motherboard expects for full-speed recognition.

Replaces non-ECC or mismatched-speed modules

Swapping older non-ECC DIMMs or slower DDR4 kits for this set adds single-bit error correction and restores the board's rated 2666MT/s throughput. The upgrade is worth it when your workloads demand data integrity and the memory controller requires 1Rx8 unbuffered population rules.

Check motherboard manual for population order

Verify the approved DIMM slot sequence and maximum supported capacity per slot before installing. Ensure the system BIOS recognises unbuffered ECC UDIMMs and that no RDIMM or SODIMM requirement exists for your specific configuration.

Questions about this item

Will the 288-pin DDR4 UDIMM modules fit the ASUS Pro WS C246-ACE motherboard slots?

Yes, the kit uses the 288-pin DDR4 UDIMM form factor that the ASUS Pro WS C246-ACE requires; it is not an RDIMM or SODIMM so it matches the board's physical slots.

What is the correct population order for the four 8 GB sticks on the ASUS Pro WS C246-ACE?

Consult the motherboard manual for the approved DIMM population sequence; the board's memory-population rules dictate which slots to fill first for the 4 x 8 GB kit to be recognised at full capacity.

Do these ECC UDIMMs need any firmware updates or periodic maintenance after installation?

No firmware updates are required; the modules run at 1.2 V with CL19 timing and provide on-the-fly error correction, so they operate maintenance-free for the life of the system.
