The conguration options for this section vary depending on the CPU and DIMM model you
installed on the motherboard.
Ai Overclock Tuner
Allows you to select the CPU overclocking options to achieve the desired CPU internal
frequency. Conguration options:
[Auto] Loads the optimal settings for the system.
[Manual] Allows you to individually set overclocking parameters.
The following items appear only when you set the Ai Overclocking Tuner to [Manual].
BCLK Frequency
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 98.0000
MHz to 538.0000 MHz.
We recommend you to set the value based on the CPU specication, as high BCLK
frequencies may damage the CPU permanently.
BCLK Spread Spectrum
This item allows you to enhance the BCLK overclocking capability or reduce the EMI
(electromagnetic disturbance) generated by the BCLK. Set this item to [Enabled]
for EMI reduction, or set this item to [Disabled] to enhance BCLK overclocking.
Conguration options: [Auto] [Disabled] [Enabled]
