Voltage Group
In this boxed area you will see:
6 voltage groups that the LM78, LM78-j, LM79, WinBond W83781D, WinBond W83782D, WinBond W83783S is monitoring
or
1 voltage group the GL518SM can monitor
or
4 voltages group the GL520SM can monitor
To adjust the % that the voltages can be off, to enable the alarm or to change your Core voltage go to the Voltage Tab.
Some users might want to adjust the +3.3V to another voltage, again this can be done in the Voltage Tab.
