Voltage Check Pont Lte
These voltage checkpont are used to measure the current system voltages. A multmeter
(not ncluded) wll be requred to check voltages. To check the voltage, set the voltmeter
swtch to “DC”, put the postve lead (red) on the postvtve pont of the voltage source
pont and the negatve lead (black) on the GND (ground) pont. The followng table
descrbes the voltage check ponts.

Pont Descrpton
PCH_1P1V PCH 1.1 voltage. The PCH voltage s the voltage suppled to
the Platform Controller Hub.
DDR_C/D Memory channel C and D voltage. The DDR memory voltage
s the voltage suppled to the DDR memory modules on the
manboard. Lower memory tmngs may requre hgher voltages
to mantan system stablty.
DDR_A/B Memory channel A and B voltage. Refer to DDR_C/D.
CPU_SA CPU system agent voltage (MC). The CPU SA voltage s the
voltage suppled to the IMC (Integrated Memory Controller)
on the CPU. Hgher overclocks may requre a hgher CPU SA
voltage to mantan stablty.
CPU_IO CPU IO voltage (Uncore). The CPU IO voltage s the voltage
suppled to the Uncore on the CPU. Hgher overclocks may
requre a hgher CPU IO voltage to mantan stablty.
CPU_CORE CPU core voltage. The CPU core voltage s the voltage suppled
to the CPU core. Hgher overclocks may requre hgher CPU
core voltages to mantan stablty.
