CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU
Ratio.
GT Frequency
Conigure the frequency of the integrated GPU in MHz.
CPU Flex Ratio Override
Enable/Disable CPU Flex Ratio Programming. Flex Ratio can lower maximum non-
turbo, especially for CPU wihout turbo function.
BCLK Frequency
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increas-
ing the BCLK will increase the internal CPU clock speed but also affect the clock
speed of other components.
PEG/DMI Frequency
Configure the PEG/DMI Frequency setting.
BCLK Advanced Setting
Configure the BCLK Advanced setting.
BCLK SSC Mode
Configure the BCLK Spread Spectrum Mode setting.
BCLK Delay
After raising BCLK, BIOS adds a delay time (ms) for stability.
BCLK Aware Adaptive Voltage
BCLK Aware Adaptive Voltage enable/disable. When enabled, pcode will be aware
of the BCLK frequency when calculating the CPU V/F curves. This is ideal for
BCLK OC to avoid high voltage overrides.
Boot Performance Mode
Select the performance state that the BIOS will set before OS handoff. Max Battery
mode will set CPU ratio as xB till OS handoff. This option is suggested for BCLK
overclocking.
