Onboard Voltage Measurement Module
Users can use a multimeter to measure component voltages, including QPI PLL, IOH core, CPU PLL, DDR,
DDR VTT, QPI VTT, and Vcore. You can employ one of the following two ways to measure component volt-
ages.

Method I (Using the included voltage measurement cable):
Method II (Connecting the multimeter directly):
Steps:
Connect the included voltage measurement cable to a voltage
measurement header and your multimeter as shown. Please
note the red wire is the positive and must be connected to the
pin 1 (+12V).
Steps:
Connect the red lead of the multimeter to the pin 1 (+12V) of
a voltage measurement point and the black lead to the pin 2
(ground).
