AVX2 Ratio Offset
AVX2 Ratio Offset specifies a negative offset from the CPU Ratio for AVX workloads. AVX
is a more stressful workload that lower the AVX ratio to ensure maximum possible ratio
for SSE workloads.
CPU E-Core Ratio
The E-Core speed is determined by the E-Core Ratio multiplied with the BCLK. Increasing
the E-Core Ratio will increase the internal E-Core clock speed without affecting the clock
speed of other components.
Configuration options: [Auto] [All Core] [Per Core] [Specific Per Core]
CPU Cache Ratio
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU Ratio.
Min Cache Ratio
The CPU internal bus speed minimum ratio. To align cache ratio with P-Core ratio for
non-K CPU, you can try to sync Min Cache Ratio Limit with CPU Cache Ratio.
GT Frequency
Allows you to configure the frequency of the integrated GPU in MHz. This item appears
when you use the onboard graphics.
CPU Flex Ratio Override
Allows you to enable or disable CPU Flex Ratio Programming. Flex Ratio can lower
maximum non-turbo, especially for CPU without turbo function.
Configuration options: [Auto] [Enabled]
CPU Flex Ratio
This value must be between Max Efficiency Ratio (LFM) and Maximum non-turbo ratio
set by Hardware (HFM).
BCLK Frequency
The CPU speed is determined by the CPU Ratio multiplied with the BCLK. Increasing the
BCLK will increase the internal CPU clock speed but also affect the clock speed of other
components.
PEG/DMI Frequency
Allows you to configure the PEG/DMI Frequency.
