Voltage Checkponts: FV1
These voltage checkpont are used to measure the current CPU core/ CPU IO/ CPU_
GFX/ DDR/ PCH voltages. A multmeter (not ncluded) wll be requred to check volt-
ages. To check the voltage, please use the ncluded voltage checkpont connectors
ncluded n the motherboard package. Attach the postve lead of the multmeter to the
voltage checkpont connector and the negatve lead to the ground connector.

CPU core voltage: measure the current CPU core voltage by pluggng the postve
lead n the VCCP pont (Pn 1) and the negatve lead n the GND pont (Pn 6). The
CPU core voltage s the voltage suppled to the CPU core. Hgher overclocks may
requre hgher CPU core voltages to mantan stablty.

CPU I/O Voltage: measure the current system bus nput supply voltage by pluggng
the postve lead n the CPU_VTT pont (Pn 2) and the negatve lead n the GND
pont (Pn 6). The CPU I/O voltage s the voltage suppled to the IMC (Integrated
Memory Controller) on the CPU. Hgher overclocks may requre a hgher CPU I/O
voltage to mantan stablty.

CPU_GFX Voltage: measure the current IGP core voltage by pluggng the postve
lead n the CPU_GFX pont (Pn 3) and the negatve lead n the GND pont (Pn 6).
The CPU_GFX voltage s the voltage suppled to the ntegrated graphcs processor
located on the CPU.
