Step 1: Press Delete to enter the BIOS.

Step 2: Select "Frequency/Voltage Control" in the main menu.

If your motherboard interface is in Chinese, please select "Frequency/Voltage Control".

Part III: After seeing "Host cpu/DIMM/PCI Clock" and "cpu Clock Ratio", the former option is set to cpu external frequency, and the latter option is set to CPU frequency doubling.

When changing the external frequency, move the cursor to "Host CPU/DIMM/PCI Clock" and press the Page Up key or the Page Down key to change.

Step 4: Its value can be adjusted from 100MHz to 133MHz, which is to improve the performance of CPU by increasing its external frequency.

Step 5: CPU with unlocked frequency multiplication can overclock by increasing frequency multiplication. Choosing the appropriate frequency doubling in the "PU clock ratio" option can greatly improve CPU performance. But now the CPU is usually locked.
