CPU overclocking how to set in BISS

There are two main brands of BIOS on the market today, one is PHOENIX-Award?BIOS and the other is AMI?BIOS, here is Award?BIOS for example.?

First, start your computer and press DEL to enter the motherboard's BIOS setup screen. Select SoftMenu?III?Setup (Figure 3) from the BIOS, this is the SoftMenu overclocking function of the Ascend motherboard.

After entering this function, we can see that the system automatically recognizes the CPU as 1800+. We have to enter here to change the default recognized model to User?Define (manual setting) mode (Figure 4).?

Once set to manual mode, the grayed out unselectable CPU external and multiplier frequencies are now selectable (Figure 5).?

If you need to overclock using a boosted external frequency, enter here at External?Clock: 133MHz. There are a number of external frequencies to adjust here, and you can crank it up to 150MHz or higher frequency options. Since raising the external frequency will increase the system bus frequency and affect the stability of other devices, be sure to use a PCI frequency lock.

The Multiplier?Factor item is where you adjust the CPU multiplier, enter the options area (Figure 6), and select a multiplier based on the actual CPU, such as 12.5, 13.5, or higher.

Rookie: If the system fails to boot up properly or works erratically after overclocking the CPU, I've heard that this can be fixed by increasing the CPU's core voltage, is there a reason for this?

Ameng: Yeah. This is because the power consumption of the CPU increases when it is overclocked. If the supply current remains the same, some CPUs will not work properly and stably due to insufficient power consumption. And after boosting the voltage, the CPU gains more power, making overclocking easier to succeed and more stable.?

The CPU core voltage can be set and adjusted in the BIOS (Figure 7). The Default state can be selected under normal circumstances. If the system is not stable after CPU overclocking, you can add voltage to the CPU core. However, the side effects of adding voltage are significant, firstly, CPU heat will increase, and secondly, it is easy to burn the CPU if the voltage is too high, so you must be careful when adding voltage, and generally add 0.025V, 0.05V, or 0.1V in steps of 0.025V upwards.
