  • Built with major OEM Samsung, Micron or Hynix chips for consistent quality

Exact-fit DDR5 ECC kit

This 128GB kit delivers four 32GB DDR5 5600 unbuffered ECC UDIMMs at 1.1V CL46. The modules match the ASUS ProArt B850-CREATOR WiFi NEO motherboard's required 288-pin form factor, rank structure, voltage and timing so the board recognises full capacity at rated speed without manual tuning.

Workstations needing error-correcting memory

Builders who need ECC protection for data integrity in professional workloads will benefit from single-bit error correction that prevents silent corruption and unplanned reboots. Systems that require registered DIMMs, SODIMMs or non-ECC modules cannot use this kit, and boards with different population rules or voltage requirements should look elsewhere.

128GB across four slots

Four populated slots provide 128GB of ECC capacity for large datasets, virtualisation and content-creation tasks. The 2Rx8 organisation and CL46 latency support the board's rated DDR5 5600 throughput. Expanding beyond this kit would require a motherboard with additional slots or higher-density modules, neither of which this configuration provides.

Questions about this item

Does this 128GB DDR5 kit require an ASUS ProArt B850-CREATOR WiFi NEO motherboard to function?

Yes, the kit is verified for that specific board and its 288-pin DDR5 UDIMM slots; other motherboards may not support the 2Rx8 ECC configuration at 5600 speed.

Can I add these four 32GB modules alongside existing DDR5 memory already installed?

Mixing with other DDR5 modules is not recommended because the board's population rules expect identical 2Rx8 1.1V CL46 sticks in all populated slots for stable operation.

How do I confirm the full 128GB is running at DDR5 5600 with ECC active after installation?

Enter the BIOS and verify the memory frequency reads 5600 MT/s, total capacity shows 128GB, and ECC status reports enabled for each channel.
