Z270M-STX MXM / B250M-STX MXM
CPU Configuration
Multi Core Enhancement
(for Z270M-STX MXM only)
Improve the system's performance by forcing the CPU to perform the highest
frequency on all CPU cores simultaneously. Disable to reduce power consumption .
CPU Ratio
(for Z270M-STX MXM only)
The CPU speed is determined by the CPU Ratio multiplied with the BCLK.
Increasing the CPU Ratio will increase the internal CPU clock speed without
affecting the clock speed of other components.
CPU Cache Ratio
(for Z270M-STX MXM only)
The CPU Internal Bus Speed Ratio. The maximum should be the same as the CPU
Ratio.
Minimum CPU Cache Ratio
(for Z270M-STX MXM only)
Set the minimum CPU Internal Bus Speed Ratio.
BCLK Frequency
(for Z270M-STX MXM only)
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.
BCLK Spread Spectrum
(for Z270M-STX MXM only)
Enable BCLK Spread Spectrum to reduce electromagnetic interference for passing
EMI tests. Disable to achieve higher clock speeds when overclocking.
Boot Performance Mode
Select the performance state that the BIOS will set before OS handoff.
FCLK Frequency
Configure the FCLK Frequency.
AVX Ratio Offset
(for Z270M-STX MXM only)
AVX 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.
BCLK Aware Adaptive Voltage
(for Z270M-STX MXM only)
When this item is 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.
