AMD X670/B650 Series
VDDP Voltage
VDDP is a voltage for the DDR bus signaling (PHY), and it is derived from your DRAM
Voltage (VDDIO_Mem). As a result, VDDP voltage can approach but not exceed your DRAM
Voltage.
SoC/Uncore OC Voltage(VID)
Allows you to s
pecify the SoC/Uncore voltage (VDD_SOC) to support memory and Infinity
Fabric overclocking. VDD_SOC also determines the GPU voltage on processors with
integrated graphics.
VDD Misc Voltage
Allows you to configure
the PCIe, DP Phy, PLL, ClkGen, and Pmux Supply.
DRAM VDDIO Voltage
Use this item to configure the VDDIO Voltage.
Seperate DRAM VDDIO Voltage Control
Allows you to configure
the Seperate DRAM VDDIO Voltage control setting.
DRAM VPP Voltage
Allows you to configure
the VPP Voltage supportewd by PMIC at DRAM side.
[Auto]
Select this item to apply the default setting.
External Voltage Settings
Press [Enter] to configure the voltage options.
VDDCR_CPU Voltage
Input voltage for the processor by the external voltage regulator.
[Auto]
Select this item to apply the default VDDCR_CPU voltage setting.
[Offset Mode]
°is mode allows you to configure the VDDCR_CPU voltage offset value.
[Fixed Mode]
°is mode allows you to set a fixed VDDCR_CPU voltage value.
VDDCR_CPU Load-Line Calibration
Load-Line is defined by Intel VRM Spec and affects the CPU power voltage. CPU Load-
Line Calibration helps prevent CPU voltage droop when the system is under heavy loading.
