A520M-HDVP/DASH
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 Infinity
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 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.
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
+1.8 Voltage
Configure the voltage for +1.8.
DRAM Voltage
Use this to configure DRAM Voltage. °e default value is [Auto].
