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

CORE (pin 6) CPU core power.

RING (pin 5) The CPU Ring is an interface for integrated controllers

inside the CPU. The CPU Ring voltage can aect the CPU

overclocking performance.

SA (pin 4) The SA (CPU System Agent) voltage is the voltage supplied

to the integrated memory controller inside the CPU.

DDR23 (pin 3) Memory voltage for channel C/ D. 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.

DDR01 (pin 2) Memory voltage for channel A/ B. 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.
