CLD0 VDDG IOD Voltage Control
AMD Overclocking Setup VDDG IOD represents voltage for the data portion of the Infinity
Fabric. It is derived from the CPU SoC/Uncore Voltage (VDD_SOC). VDDG can approach
but not exceed VDD_SOC.
DRAM Information
Load XMP Setting
Load XMP settings to overclock the memory and perform beyond standard specifications.
DRAM Frequency
If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assign
the appropriate frequency automatically. Setting DRAM Frequency can adjust DRAM
Timing.
DRAM Voltage
Configure the voltage for the DRAM Voltage.
Infinity Fabric Frequency and Dividers
AMD Overclocking Setup Set Infinity Fabric frequency (FCLK). Auto: FCLK = MCLK.
Manual: FCLK must be less than or equal to MCLK for best performance in most cases.
Latency penalties are incurred if FCLK and MCLK are mismatched, but sufficiently high
MCLK can negate or overcome this penalty.
DRAM Timing Configuration
External Voltage Settings and Load-line Calibration
CPU Vcore Voltage
Input voltage for the processor by the external voltage refulator.
CPU Load-Line Calibration
CPU Load-Line Calibration helps prevent CPU voltage droop when the system is under
heavy loading.
VDDCR_SOC Voltage
Configure the voltage for the VID-requested VDDCR_SOC supply level.
VDDCR_SOC Load-Line Calibration
CPU VDDCR_SOC Load-Line Calibration helps prevent VDDCR_SOC voltage droop when
the system is under heavy loading.U
