21. Multi-function POST Indicator
Multi-function POST Indicator his is a four-digit POST code reader, which displays in sets of 7-digitLED. The display can be configured to show data in regular decimal format, or hexadecimal, which means the characters available (when working as intended) are 0-9, A-F and has a cap of 255 characters.During POST, the left set of LEDs will display the various POST codes as they cycle through the Power On Self-Test. The POST codes are listed in the troubleshooting section on Page 144. After the system boots, these same set of LEDs can be set to display a hardware monitoring sensor, such as the CPU temperature in Celsius.This temperature EVGA X299 DARK (151-SX-E299)-22 -is specifically for the CPU socket, which will typically read slightly higher than a given CPU core. To read this temp in Fahrenheit, take the value in Celsius, multiply by 9/5 (or 1.8) and add 32.The display can be used to show additional temperatures,or can be configured in tandem with all 4digits to provide live readings for voltages or temperatures. For example,the LEDs can be configured to read voltages,such as1.258 or -55Cfor CPU tempforwhen you are using LN2extreme cooling.Detailed configuration instructions for the Debug Indicator are provided on Page 138.
