FV1: Voltage Checkponts Connector (optonal)
These voltage checkpont are used to measure the current system voltages.
A multmeter (not ncluded) wll be requred to check voltages. To check
the voltage, please use the ncluded voltage checkpont cables ncluded n
the motherboard package. Attach the postve lead of the multmeter to the
voltage checkpont cable and the negatve lead to the ground connector.

Descrpton
GND (pn 6, pn 7)
Ground
PCH_1P05 (pn 5)
PCH 1.5 voltage. The PCH voltage s the voltage suppled to
the Platform Controller Hub.
VCC_DDR (pn 4)
Memory voltage. The DDR memory voltage s the voltage
suppled to the DDR memory modules on the motherboard.
Lower memory tmngs may requre hgher voltages to
mantan system stablty.
CPU_GFX (pn 3)
The CPU_GFX voltage s the voltage suppled to the
ntegrated graphcs processor located on the CPU.
CPU_VTT (pn 2)
CPU IO voltage (Uncore). The CPU IO voltage s the voltage
suppled to the Uncore on the CPU. Hgher overclocks may
requre a hgher CPU IO voltage to mantan stablty.
VCCP (pn 1)
CPU core voltage. The CPU voltage s the voltage suppoed
to the CPU core. Hgher overclocks may requre hgher CPU
core voltages to mantan stablty.
