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 manboard package. Attach the
postve lead of the multmeter to the voltage checkpont cable and the negatve lead to
the ground connector.

PCH 1.5 voltage. The PCH voltage s the voltage suppled to
the Platform Controller Hub.
Memory voltage. The DDR memory voltage s the voltage
suppled to the DDR memory modules on the manboard.
Lower memory tmngs may requre hgher voltages to
mantan system stablty.
The CPU_GFX voltage s the voltage suppled to the
ntegrated graphcs processor located on the CPU.
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.
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.
