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.

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.
