Plug in the CPU fan cable to the 3-pin
CPUFAN1
connector. If you have chassis fan, you
can also plug it in
SYSFAN2
or
SYSFAN3
connector.
This motherboard comes with a 20-pin and 4-pin ATX power connector as shown below.
Make sure you plug in the right direction. We strongly recommend you to insert the 4-pin
connector before connecting the 20-pin connector.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected.
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. The default setting is "table select
mode". You can adjust the FSB from "CPU Host/SDRAM/PCI Clock" for overclocking.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
3. ATX Power Connectors
Note: Some CPU fans
do not have sensor pin
so they cannot support
fan monitoring.
CPUFAN1 Connector
Warning: Intel 845GV supports
maximum 533MHz system bus and
66MHz AGP clock; higher clock
setting may cause serious system
damage.
