1.
Pull up the CPU socket lever and up to
90-degree angle.
2.

5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.05V to 1.825V. It is not necessary to set CPU Core Voltage
Setting CPU Frequency
This motherboard is CPU jumper-less design, the system can detect the CPU frequency
automatically, and no jumpers or switches are needed.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
