BCLK Frequency [100.00]
This item allows you to set the BCLK (base clock) frequency to enhance the system
performance. Use the <+> or <‑> to adjust the value. The values range from 40.0 MHz to
500.0 MHz.
We recommend you to set the value based on the CPU specification, as high BCLK
frequencies may damage the CPU permanently.
BCLK Amplitude [Auto]
This item allows you to set the magnitude of the base clock driven for the processor. High
values may improve overclocking stability. Configuration options: [Auto] [700mV] [800mV]
[900mV] [1000mV]
BCLK Frequency Slew Rate [Auto]
This item allows you to set the frequency update rate. Lower values speed up clock changes.
