Intel Desktop Board DX58SO2 Product Guide

Base Clock Frequency Increase Switch

This button switch can be used to overclock the board by increasing the processor’s Base Clock (BCLK) frequency by 1 MHz each time the switch is pressed. If the button is held down for approximately 0.5 seconds, the BCLK frequency will continue to increase by 1-MHz steps approximately once every 0.1 second.

The BCLK frequency is used to set the frequencies of all major functional parts of the system. Among them are processor frequency, the Uncore Clock (UCLK), the memory frequency, and the frequency of the QPI interface

Base Clock Frequency Decrease Switch

This button switch can be used during overclocking to decrease the system’s Base Clock (BCLK) frequency by 1 MHz each time the switch is pressed. If the button is held down for approximately 0.5 seconds, the BCLK frequency will continue to decrease by 1-MHz steps approximately once every 0.1 second.

Power Switch

The power button switch (see Figure 5, C) can be used to turn the desktop board on or off. This power button switch behaves the same as a chassis power switch connected via the front panel header. The onboard power button switch does not remove standby power. To turn off the computer using the onboard power button switch, keep it pressed down for three seconds.

Reset Switch

The reset button switch (see Figure 5, D) can be used to reset the desktop board. This power button switch behaves the same as a chassis reset switch connected via the front panel header. When the reset button switch is pressed, the board resets and runs the POST.
