Description

GND (pin 6, pin 7)

Ground

PCH_1P05 (pin 5)

PCH 1.5 voltage. The PCH voltage is the voltage supplied to

 

the Platform Controller Hub.

VCC_DDR (pin 4)

Memory voltage. The DDR memory voltage is the voltage

 

supplied to the DDR memory modules on the mainboard.

 

Lower memory timings may require higher voltages to

 

maintain system stability.

CPU_GFX (pin 3)

The CPU_GFX voltage is the voltage supplied to the

 

integrated graphics processor located on the CPU.

CPU_VTT (pin 2)

CPU IO voltage (Uncore). The CPU IO voltage is the voltage

 

supplied to the Uncore on the CPU. Higher overclocks may

 

require a higher CPU IO voltage to maintain stability.

VCCP (pin 1)

CPU core voltage. The CPU voltage is the voltage suppoied

 

to the CPU core. Higher overclocks may require higher CPU

 

core voltages to maintain stability.
