Jp23 Adjust Fsb/Pci Clock - AOpen MX36LE-UI Installation Manual

3. Installing CPU & Housing Fan
Plug in the CPU fan cable to the 3-pin CPUFAN connector. If you have a housing fan,
you can also plug it on FAN2 connector.
FAN2

4. JP23 Adjust FSB/PCI Clock

This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if
you are not an overclocker, we recommend you to set at the default setting.

Note: Some CPU fans do not have
sensor pin, so that they cannot
support fan monitoring.

5. Setting CPU Voltage & Frequency
CPU Core Voltage Auto-Detection
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected. It is not necessary to set CPU Core Voltage.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through the
BIOS setup, and no jumpers or switches are needed.
BIOS Setup > Frequency/Voltage Control > CPU Host Clock (CPU/PCI)
Core Frequency = CPU FSB Clock * CPU Ratio
