SoC/Uncore OC Voltage(VID)
Specify the SoC/Uncore voltage (VDD_SOC) in mV to support memory and Innity Fabric
overclocking. VDD_SOC also determines the GPU voltage on processors with integrated
graphics. “SoC/Uncore OC Mode” needs to be enabled to force this voltage.
CLD0 VDDP Voltage Control
AMD Overclocking Setup VDDP is a voltage for the DDR4 bus signaling (PHY), and it is
derived from your DRAM Voltage (VDDIO_Mem). As a result, VDDP voltage in mV can
approach but not exceed your DRAM Voltage.
CLD0 VDDG CCD Voltage Control
AMD Overclocking Setup VDDG CCD represents voltage for the data portion of the Innity
Fabric. It is derived from the CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach
but not exceed VDD_SOC.
CLD0 VDDG IOD Voltage Control
AMD Overclocking Setup VDDG IOD represents voltage for the data portion of the Innity
Fabric. It is derived from the CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach
but not exceed VDD_SOC.
