Voltage Checkpoints - MSI X99S GAMING 9 AC Guide Rapide

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
Ground
CPU core power.
VPP VR power source for channel C/ D DDR memory.
VPP VR power source for channel A/ B DDR memory.
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.
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.
The CPU VCCIN voltage is the CPU power source that is
shared with components of the CPU.
