Does anyone know how to set up the jumper on the Songjing 694X motherboard?

Forget it! That's great! You can burn the CPU!

Try them one by one and find out.

Fooling around, it can't be broken anyway. Besides, this computer is too old to tinker with, and it will be replaced if it is broken.

Each motherboard is different, I can't say, I can only read the manual by myself.

A jumper is a small switch that controls the flow of current on a circuit board. Its function is to adjust the on-off relationship of different electrical signals on the device, and to adjust the working state of the device, such as determining the motherboard voltage, the master-slave relationship of the driver, etc. The jumper is basically composed of two parts, one part is fixed on the motherboard, hard disk and other equipment, and is composed of two or more metal jump pins (as shown in Figure 1; The other part is the jumper cap (as shown in Figure 2), which is a movable part, the outer layer is insulating plastic, and the inner layer is conductive material, which can be inserted on the jumper pins to connect the two jumper pins.

Figure 1: Metal skipping stitch.

Fig.2. Jumper caps.

When the jumper cap is buckled on the two jumper pins, it is in the ON state, and there is a current passing through, which we call on; On the contrary, when the jumper cap is not buckled, it means that it is disconnected, which is called off. Let's take a look at Zheng Yun, where are the jumpers?

Tips: It is very important to adjust the jumper, if the jump is wrong, it will crash, and even burn the entire equipment in serious cases, so you must read the manual carefully when adjusting the jumper, and check the jumper name, jumper column number and on-off relationship.

1. CMOS jumper.

CMOS jumpers are mostly near the motherboard battery. It's relatively simple to set up, and there are only two ways: normal and clear CMOS (there will be a jumper description near the jump line in the CMOS jumper).

When set to 1-2 (shorted), it is normal; When set to 2-3 (shorted), it can be used to clear the CMOS password and boot password to clear the CMOS settings (as shown in Figure 6).

Clear CMOS content jumpers are firm with two, horizontal with three pin angles.

Motherboard manual.

Look directly at what you can't generally understand.

are marked on the motherboard. You can also read the manual.

Look at it, there is a picture, it is very clear.

The frequency doubling front sideband x the outer frequency are all above 133.

You take a closer look at what is on the board.

Be careful not to pick a burn.

You can go to ** to download it, and there will be a silk screen description on the motherboard in the jumper, but it's very small, and you have to pay attention to it.

There is an official station, you can go and be it.

That's because the positive and negative poles of your Power LED and HDD LED light-emitting diodes are reversed, The motherboard generally has a diagram of the positive and negative poles, if the board is not a well-known brand, how do you plug it in now, it is generally good to plug it in the other way, if you can't find it, just look at the manual, there is a schematic diagram of the front panel installation on it.

There are usually very small English words on the motherboard, and you are generally no problem with the corresponding connection.

This depends on what CPU you are using, and adjust the jumper according to the corresponding external frequency of the CPU. The first item is CPU auto-selection, which is the default. It's the CPU of the Tualatin core, and the external frequency is 100MHz, so just dial the jumper to 66 100MHz.
