Error C5 Asus ROG Crosshair X670E Hero indicates a specific issue during operation.
Error C5 ram issue reported. I thought it might be related to the RAM but based on my research, I know the motherboard supports XMP and 6000mhz. I checked everything carefully, updated the BIOS, and tried connecting RAM one at a time. Now I'm focusing on slot A2 and B2 connection, which is one of the solutions suggested. Could you provide more guidance or alternatives? Thank you for your help!
Place them in slots A2 and B2 for a guaranteed fix. The board uses a daisy chain design, making A2 and B2 the best positions on that chain. With DDR5 technology and its speed, the system often fails to boot unless placed correctly due to signal integrity problems in the chain. You could attempt updating the BIOS via BIOS flashback, but swapping A2 and B2 should resolve the issue—just follow the 2-minute memory training afterward.
