Getting Started

Voltage Checkpoints

These voltage checkpoints are used to measure the current system voltages. A

multimeter (not included) will be required to check voltages.

FV1: V-Check Connectors

To check the voltage, please use the optional voltage checkpoint cables included in

the motherboard package. Attach the positive lead of the multimeter to the voltage

checkpoint cable and the negative lead to the ground connector.

Description

GND (pin 7~9)

Ground

C_SA (pin 6)

The CPU_SA (CPU System Agent) voltage is the voltage

supplied to the integrated memory controller inside the

CPU.

RING (pin 5)

The CPU Ring is an interface for integrated controllers

inside the CPU. The CPU Ring voltage can affect the CPU

overclocking performance.

GFX (pin 4)

The CPU_GFX voltage is the voltage supplied to the

integrated graphics processor located on the CPU.

CORE (pin 3)

CPU core0 voltage. The CPU voltage is the voltage

supplied to the CPU core. Higher overclocks may require

higher CPU core voltages to maintain stability.

DDR (pin 2)

Memory voltage. The DDR memory voltage is the voltage

supplied to the DDR memory modules on the motherboard.

Lower memory timings may require higher voltages to

maintain system stability.

VCCIN (pin1)

The CPU VCCIN voltage is the CPU power source that is

shared with components of the CPU.
