D-Led™ & D-Bracket™ (Optional) - MSI K7T TURBO2 - K7T Turbo 2 Motherboard User Manual

Chapter 1
D-LED™ & D-Bracket™ (Optional)
The optional D-LED™ uses graphic signal display
to help users understand their system. Four LEDs embed-
ded in the mainboard 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 D-Bracket™, which integrates four LEDs, is
optional. The definitions of D-Bracket™ LED signals are the same as D-
LED™.
