D-LED™ (Optional)
The D-LED™ (Diagnostic LED) uses graphic signal display to help users
understand their system. Four LEDs (LED1 ~ LED4) embedded on the main-
board provide up to 16 combinations of signals to debug the system. The 4
LEDs can debug all problems that fail the system, such as VGA, RAM or other
failures. This special feature is very useful for the overclocking users. These
users can use the feature to detect if there are any problems or failures. The
definitions of LED signal combinations are listed below:
