Exact DDR5-5600 ECC upgrade

This 128 GB kit contains two 64 GB unbuffered UDIMM modules built to the DDR5-5600 (PC5-44800) standard with CL46 latency and 1.1 V operation. It is validated for the ASUS ProArt B850-CREATOR WiFi NEO motherboard and will be recognised at full capacity and rated speed by the board's memory controller.

Cool and efficient operation

The modules run at the standard 1.1 V DDR5 voltage and carry no heat spreader, so they rely on normal chassis airflow for cooling. Power draw stays within the DDR5 baseline for 5600 MT/s operation, and the unbuffered design adds no active components that would increase noise or thermal load.

ECC protection for data integrity

On-die error-correcting code detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots during long compute sessions. Buyers who need registered DIMMs or non-ECC memory for a different platform cannot use this kit.
