Onboard LEDs

The motherboard comes with a set of LEDs that indicate the voltage conditions of CPU, memory,
northbridge and southbridge. You may adjust the voltages in BIOS. There are also an LED for
hard disk drive activity and an onboard switch for power status. For more information about
voltage adjustment, refer to 3.3 Extreme Tweaker menu.
1. Voltiminder LED II
Voltiminder LED II provides not only many measurement spots for various voltages
but LEDs indicating which voltage is being polled. This is especially useful when
debugging overclock failures. Voltiminder LED II consists of the following LED set:
GND, CPU_VCORE, CPU_VSA, CPU_VTT, PCH_1.1V, PCH_1.5V, DRAM_AB, and
DRAM_CD. For example, when you fail to post and see the LED for CPU_VTT light up,
the system is alerting you that the setting for CPU VTT should be readjusted.
