the appropriate frequency automatically. Setting DRAM Frequency can adjust DRAM
Timing.
DRAM Voltage
Congure the voltage for the DRAM Voltage.
Innity Fabric Frequency and Dividers
AMD Overclocking Setup Set Innity 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 suciently high
MCLK can negate or overcome this penalty.
DRAM Timing Conguration
External Voltage Settings and Load-line Calibration
Voltage Mode
[OC]
If this option is selected, there is larger range voltage for overclocking.
[Normal]
If this option is selected, there is smaller range voltage for normal system.
CPU Core/Cache Voltage
Input voltage for the processor by the external voltage refulator.
CPU Core/Cache Load-Line Calibration
CPU Core/Cache Load-Line Calibration helps prevent CPU voltage droop when the system
is under heavy loading.
CPU VDDCR_SOC Voltage
Congure the voltage for the VID-requested VDDCR_SOC supply level.
CPU 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
VPPM
Congure the voltage for the VPPM.
2.50V Voltage
Use this to select 2.50V Voltage. e default value is [Auto].
