Overclocking a computer is done by Artificially increase the working frequency of CPU, graphics card and other hardware so that they can work stably at a frequency higher than their rated frequency. Take the Intel P4C 2.4GHz CPU as an example. Its rated operating frequency is 2.4GHz. If the operating frequency is increased to 2.6GHz and the system can still run stably, then the overclocking is successful this time.

The main purpose of CPU overclocking is to increase the working frequency of the CPU, which is the main frequency of the CPU. The main frequency of the CPU is the product of the FSB and the multiplier. For example, the FSB of a CPU is 100MHz and the multiplier is 8.5. It can be calculated that its main frequency = FSB × multiplier = 100MHz × 8.5 = 850MHz.

Increasing the main frequency of the CPU can be achieved by changing the CPU multiplier or FSB. But if you are using an Intel CPU, you can ignore the multiplier because Intel CPU uses a special manufacturing process to prevent the multiplier from being modified. AMD's CPU can modify the multiplier, but modifying the multiplier does not improve CPU performance as much as the FSB.

The speed of the FSB is usually closely related to the speed of the front-side bus and memory. Therefore, when you increase the CPU FSB, the performance of the CPU, system and memory are also improved at the same time.

There are two main methods for CPU overclocking:

One is hardware settings and the other is software settings. Among them, hardware settings are more commonly used, and they are divided into jumper settings and BIOS settings.

1. Jumper settings for overclocking

Most early motherboards used jumper or DIP switch settings for overclocking. Near these jumpers and DIP switches, there are often some tables printed on the motherboard, which record the functions defined by the combination of jumpers and DIP switches. In the off state, you can set the frequency according to the table. After restarting, if the computer starts normally and runs stably, it means our overclocking is successful.

For example, an Intel 845D chipset motherboard used with Celeron 1.7GHz uses jumper overclocking. Below the inductor coil, we can see the jumper description table. When the jumper is set to 1-2, the FSB is 100MHz. When it is changed to 2-3, the FSB is increased to 133MHz. The default FSB of Celeron 1.7GHz is 100MHz. As long as we increase the FSB to 133MHz, the original Celeron 1.7GHz will be overclocked to work at 2.2GHz. Isn’t it very simple? :).

Another VIA KT266 chipset motherboard used with AMD CPU uses DIP switch setting to set the CPU frequency multiplier. Most AMD multipliers are not locked, so you can overclock by modifying the multiplier. This is a five-group DIP switch that can be combined to form more than a dozen modes through the different on-off states of each serial number switch. There is an instruction table printed on the upper right side of the DIP switch, which explains the different frequency changes brought about by the DIP switch in different combinations.

For example, when we overclock an AMD 180, we must first know that the main frequency of the Athlon XP 180 is equal to 133MHz FSB × 11.5 times the frequency. As long as we increase the multiplier to 12.5, the CPU main frequency will become 133MHz×12.5≈1.6GHz, which is equivalent to Athlon XP 200. If we increase the multiplier to 13.5, the CPU main frequency becomes 1.8GHz, and the Athlon XP 180 is overclocked to become the Athlon XP220. A simple operation can bring about a huge improvement in performance, which is very interesting.

2. BIOS settings for overclocking

Nowadays, mainstream motherboards have basically given up on jumper settings and DIP switch settings to change the CPU multiplier or FSB, and instead use more Convenient BIOS settings.

For example, Abit's SoftMenu III and EPOX's PowerBIOS are BIOS overclocking methods. You can set the CPU multiplier and FSB in the CPU parameter settings. Certainly. If the computer cannot start normally after overclocking, just shut down the computer, hold down the INS or HOME button, and then restart the computer. The computer will automatically return to the default working state of the CPU, so it is better to overclock in the BIOS.

Here we use the combination of ABIT NF7 motherboard and Athlon XP 180 CPU to achieve this overclocking practice. There are currently two main brands of BIOS on the market, one is PHOENIX-Award BIOS, and the other is AMI BIOS. Here we take Award BIOS as an example.

First start the computer and press the DEL key to enter the motherboard's BIOS setting interface. Select Soft Menu III Setup from the BIOS, this is the SoftMenu overclocking function of ABIT motherboard.

After entering this function, we can see that the system automatically recognizes the CPU as 180. We need to press Enter here to change the default recognized model to User Define (manual setting) mode. After setting to manual mode, the original gray unselectable CPU FSB and frequency multiplier now become selectable.

If you need to increase the FSB for overclocking, just press Enter at External Clock: 133MHz. There are many FSBs to adjust here, and you can adjust it to 150MHz or higher frequency options. Since increasing the FSB will increase the system bus frequency and affect the stability of other devices, it is necessary to lock the PCI frequency.

The Multiplier Factor item is where you adjust the CPU multiplier. Enter the option area after pressing Enter. You can select the multiplier according to the actual situation of the CPU, such as 12.5, 13.5 or higher.

Rookie: If the system cannot start normally or works unstable after overclocking the CPU, I heard that it can be solved by increasing the core voltage of the CPU. Does this make sense?

Ameng: Yes. Because after the CPU is overclocked, the power consumption will also increase. If the supply current remains unchanged, some CPUs will not be able to work normally and stably due to insufficient power consumption. After increasing the voltage, the CPU gets more power, making overclocking more successful and stable.

The core voltage of the CPU can be set and adjusted in the BIOS (Figure 7). Under normal circumstances, you can select the Default state. If the system is unstable after overclocking the CPU, you can add voltage to the CPU core. However, adding voltage has great side effects. Firstly, the heat generated by the CPU will increase. Secondly, if the voltage is too high, it will easily burn the CPU. Therefore, you must be careful when adding voltage. Generally, increase the voltage in steps of 0.025V, 0.05V or 0.1V. That's it.

3. Use software to achieve overclocking

As the name suggests, overclocking is achieved through software. This kind of overclocking is simpler, and its characteristic is that the set frequency will be restored after shutting down or restarting the computer. If a novice is afraid of overclocking with hardware settings at once, he can first use software overclocking to test the overclocking effect. The most common overclocking software includes SoftFSB and software developed by each motherboard manufacturer.

Their principles are similar, and they all achieve the purpose of overclocking by controlling the frequency of the clock generator.

SoftFSB is a relatively general software that can support dozens of clock generators. Just select the clock generator model used on the motherboard, click GET FSB to gain control of the clock generator, and then use the frequency lever to set the overclocking. After selecting, press Save to let the CPU press The newly set frequency starts working. However, the disadvantage of software overclocking is that when the frequency you set is beyond the CPU's ability to bear, it will cause a crash or system crash the moment you click save.

CPU overclocking secrets:

1. CPU overclocking is related to the "physique" of the CPU itself

Many friends say that their CPU still does not work well after overclocking. Stability, this is a "physical" issue. For the same model of CPU, the superlability of production in different cycles is different, which can be reflected from the processor number.

2. CPUs with low multipliers are very good

Everyone knows that increasing the CPU FSB improves performance faster than increasing the CPU multiplier. If it is a CPU that does not lock the multiplier, experts will The method of increasing the FSB and reducing the multiplier is used to achieve better results. From this, it can be concluded that the CPU with a low multiplier has inherent advantages. For example, overclocking masters AMD Athlon XP170/180 and Intel Celeron 2.0GHz.

3. The more advanced the manufacturing process, the better.

The more advanced the manufacturing process, the higher the CPU frequency can be achieved during overclocking. For example, Intel's newly launched Intel Celeron D processor, which has won widespread attention, uses a 90-nanometer manufacturing process and a Prescott core. Some netizens have already upgraded the Celeron D which is running at 2.53GHz to 4.4GHz.

4. Temperature has a decisive influence on overclocking

Everyone knows that the temperature of the CPU will increase significantly after overclocking, and a good cooling system is necessary. This not only refers to the CPU fan, but also the chassis fan, etc. In addition, it is also important to apply a thin layer of silicone grease on the CPU core to help the CPU dissipate heat well.

5. The motherboard is a powerful tool for overclocking

A motherboard that can support overclocking generally has the following advantages: (1) Supports high FSB. (2) Have a good power supply system. For example, use a three-phase power supply motherboard or a motherboard with a single-channel single-channel power supply for the CPU. (3) Motherboard with special protection. For example, when the CPU fan stops spinning, the power can be cut off immediately. Some motherboards call this "burn-proof technology". (4) Motherboards with special overclocking settings in the BIOS. (5) Excellent workmanship, preferably a 6-layer PCB board.

Nine possibilities for high CPU usage?

1. Anti-virus software causes malfunctions?

Since the new versions of KV, Kingsoft, and Rising have all added anti-virus software to Random monitoring of web pages, plug-ins, and emails undoubtedly increases the burden on the system. Solution: There is basically no reasonable solution. Try to use the least monitoring service, or upgrade your hardware configuration. ?

2. The driver has not been certified, causing CPU resources to occupy 100%?

A large number of test versions of drivers are flooding the Internet, causing hard-to-find fault causes. Handling method: Pay special attention to the graphics card driver. It is recommended to use Microsoft-certified or officially released drivers, and strictly check the model and version. ?

3. Caused by viruses and Trojans?

A large number of worms replicate rapidly within the system, causing the CPU resource usage to remain high. Solution: Use reliable anti-virus software to completely clean the system memory and local hard disk, and open the system settings software to check whether there are any programs that start abnormally. Regularly update and upgrade anti-virus software and firewalls, strengthen anti-virus awareness, and master correct anti-virus knowledge. ?

4. Control Panel - Management Tools - Services - RISING REALTIME MONITOR SERVICE, right-click the mouse and change to manual. ?

5. Start->Run->msconfig->Start, close unnecessary startup items, and restart. ?

6. Check the "svchost" process.

?

svchost.exe is a core process of Windows XP system. svchost.exe not only appears in Windows XP, but also exists in Windows systems using the NT kernel. Generally, the number of svchost.exe processes in Windows 2000 is 2, but in Windows XP, the number of svchost.exe processes rises to 4 or more. ?

7. Check the network connection. Mainly the network card. ?

8. Check the network connection?

When a computer with Windows XP installed as a server receives a connection request on port 445, it will allocate memory and a small amount of space. Allocate CPU resources to serve these connections. When overloaded, the CPU occupancy rate may be too high because of the inherent trade-off between the number of work items and responsiveness. You'll want to determine the appropriate MaxWorkItems settings to improve system responsiveness. If the value set is incorrect, the server's responsiveness may be affected, or a user may monopolize too many system resources. ?

To solve this problem, we can solve it by modifying the registry: Expand the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver] branch in the registry editor and create a new one in the right window DWORD value named "maxworkitems". Then double-click the value, type the following value in the window that opens and save and exit:?

If the computer has more than 512MB of memory, type "1024"; if the computer has less than 512 MB of memory, type "256". ?

9. Check if using the right mouse button in Windows XP causes the CPU to occupy 100%?

A report not long ago said that using the right mouse button in the resource manager will cause the CPU resource to be 100%. % occupied, let’s see what’s going on? ?

Symptoms:?

In the resource manager, when you right-click a directory or a file, you may have the following problems:?

< p>At that time any file copy operations will likely stop responding?

Network connection speeds will be significantly reduced?

All streaming input/output operations such as those using Windows Media Player listening to music may be the cause of music distortion:?

When you right-click a file or directory in the resource manager, when the shortcut menu is displayed, the CPU usage will increase to 100% , and only returns to normal levels when you close the shortcut menu. ?

Solution:?

Method 1: Turn off "Use transition effects for menus and tooltips"?

1. Click "Start"--" Control Panel"?

2. Double-click "Display" in "Control Panel"?

3. Click the "Appearance" tab in "Display" properties?

4. Click "Effects" in the "Appearance" tab?

5. In the "Effects" dialog box, clear the check box in front of "Use transition effects for menus and tooltips" Then click the "OK" button twice. ?

Method 2: When using the right mouse button to click on a file or directory, first use the left mouse button to select your target file or directory. Then use the right mouse button to pop up the shortcut menu. ?

Under normal circumstances, if the CPU accounts for 100%, our computer will always slow down, and many times we can solve it by making a few changes without having to ask those prawns. ?

When the machine slows down, the first thing we think of is of course the task manager to see which program accounts for the greater proportion. If it is a large program, it can be forgiven. After closing the program, as long as the CPU is normal, then there is no problem; if not, then you have to find out what the program is. When you can't find out what the process is, search on Google or Baidu.

Sometimes it is useless to just end it. Under XP, we can combine the startup items in msconfig to turn off some unused items. Under 2000, you can go to the next winpatrol to use it. ?

Some commonly used software, such as browsers, occupy a lot of CPU, so the software needs to be upgraded or simply replaced with other similar software. Sometimes the software and the system are a little incompatible. Of course, we You can try the compatibility item given to us under the XP system, right-click the .exe file and select compatibility. ?

Svchost.exe is sometimes a headache. When you see that one of your svchost.exe takes up a lot of CPU, you can go to the next aports or fport to check its corresponding program path. Something is using this svchost.exe. If it is not under c:\Windows\system32(xp) or c:\winnt\system32(2000), then it is suspicious. Update your anti-virus software. ?

We will also encounter 100% CPU usage when right-clicking a file. Sometimes right-clicking to pause may be the problem. Official explanation: First left-click to select, then right-click (I don’t quite understand). Unofficial: Solved by right-clicking on the desktop-Properties-Appearance-Effects and unchecking "Use the following excessive effects (U) for menus and tooltips". Some anti-virus software will also have an impact on file monitoring. You can turn off the file monitoring of anti-virus software; the same is true for monitoring web pages, plug-ins, and emails. ?

Some drivers may sometimes experience this phenomenon. It is best to choose Microsoft-certified or officially released drivers to install. Sometimes you can upgrade the driver appropriately, but remember that the latest is not the best. . ?

CPU cooling software, because the software will use all CPU idle time to cool down when running, but Windows cannot distinguish the difference between ordinary CPU usage and the cooling instructions of the cooling software, so the CPU is always If it shows 100%, there is no need to worry about this, it will not affect normal system operation. ?

When processing larger word files, word's spelling and grammar checking will tire the CPU. Just open Word's Tools - Options - Spelling and Grammar and uncheck "Check Spelling and Check Grammar". ?

The reason why the CPU usage is high after clicking the avi video file is because the system needs to scan the file first, check all parts of the file, and create an index; solution: right-click the folder where the video file is saved-Properties -General-Advanced, uncheck Allow Indexing Service to index this folder for fast searches

The part of the computer that performs various arithmetic and logical operations. The basic operations of the arithmetic unit include the four arithmetic operations of addition, subtraction, multiplication, and division, logical operations such as AND, OR, NOT, and XOR, as well as operations such as shifts, comparisons, and transmissions. It is also called the Arithmetic Logic Unit (ALU). When the computer is running, the operations and types of operations of the arithmetic units are determined by the controller. The data processed by the operator comes from the memory; the processed result data is usually sent back to the memory or temporarily stored in the operator.

Data The processing object of the operator is data, so the data length and computer data representation method have a great impact on the performance of the operator. In the 1970s, microprocessors often used 1, 4, 8, and 16 binary bits as the basic unit for processing data. Most general-purpose computers use 16, 32, or 64 bits as the length of data processed by the arithmetic unit. An arithmetic unit that can process all bits of a data simultaneously is called a parallel arithmetic unit. If only one bit is processed at a time, it is called a serial operator. Some operators can process several bits at a time (usually 6 or 8 bits). A complete data is divided into several segments for calculation, which is called a serial or parallel operator. Operators tend to only process data of one length. Some can also handle data of several different lengths, such as half-word-length operations, double-word-length operations, quadruple-word-length operations, etc. Some data lengths can be specified during the operation, which is called variable word length operation.

According to different representation methods of data, there can be binary operators, decimal operators, hexadecimal operators, fixed-point integer operators, fixed-point decimal operators, floating-point operators, etc. According to the nature of the data, there are address operators and character operators.

Operation The number of operations and operating speed that the arithmetic unit can perform indicates the strength of the arithmetic unit and even the ability of the computer itself. The most basic operation of the arithmetic unit is addition. Adding a number to zero is simply transmitting the number. Completing the code of one number and adding it to another number is equivalent to subtracting the previous number from the latter number. Subtract two numbers to compare their magnitudes.

Left and right shifting is the basic operation of the arithmetic unit. In signed numbers, the sign does not change but only the data bits are shifted, which is called arithmetic shift. If the data is moved together with all bits of the symbol, it is called a logical shift. If the highest bit and lowest bit of data are linked to perform a logical shift, it is called circular shift.

The logical operation of the arithmetic unit can perform bitwise AND, OR, XOR of two data, and negate the bits of one data. Some operators can also perform 16 logical operations on binary codes.

Multiplication and division operations are more complex. Many computer arithmetic units can directly complete these operations. The multiplication operation is based on the addition operation. The partial products are generated successively under the decoding control of one or more bits of the multiplier, and the partial products are added to obtain the product. The division method is often based on multiplication, that is, a number of factors are selected to be multiplied by the divisor to make it approximately 1. When these factors are multiplied by the dividend, the quotient is obtained. Computers that do not have the hardware to perform multiplication and division can use programs to perform multiplication and division, but at a much slower speed. Some operators can also perform complex operations such as finding the maximum number in a batch of numbers, continuously performing the same operation on a batch of data, and finding square roots.

Operation method To implement the operation of the arithmetic unit, especially the four arithmetic operations, a reasonable operation method must be selected. It directly affects the performance of the arithmetic unit, and is also related to the structure and cost of the arithmetic unit. In addition, when performing numerical calculations, the significant digits of the result may be longer, and a certain number of significant digits must be intercepted, resulting in the rounding problem of the least significant digit. The rounding rule chosen also affects the accuracy of the calculation results.

Structure The arithmetic unit includes three parts: register, execution unit and control circuit.

There are three registers in a typical arithmetic unit: a receiving register that receives and saves an operand; an accumulation register that saves another operand and the result of the operation; and a multiplier that is saved when performing multiplication and division operations. Or the multiplier register of the quotient. The execution unit includes an adder and various types of input and output gate circuits. The control circuit sends out different control signals in a certain time sequence, so that the data enters the register or adder through the corresponding gate circuit to complete the specified operation.

In order to reduce access to memory, many computer arithmetic units are equipped with more registers to store intermediate calculation results so that they can be directly used as operands in subsequent operations.

In order to increase computing speed, some large computers have multiple arithmetic units. They can be different types of operators, such as fixed-point adders, floating-point adders, multipliers, etc., or they can be the same type of operators.

The arithmetic unit

is composed of an arithmetic logic unit (ALU), an accumulation register, a data buffer register and a status condition register. It is a data processing component. Compared with the controller, the arithmetic unit accepts the commands of the controller and performs actions. That is, all the operations performed by the arithmetic unit are commanded by the control signals sent by the controller, so it is an execution component.

Main functions:

Perform all arithmetic operations;?

Perform all logical operations and perform logical tests, such as zero value testing or two values comparison.

Arithmetic unit: It is a component that performs calculations. Its main function is arithmetic operations and logical operations.

Controller

controller

An instrument or complete device that generates control information for a predetermined purpose. The automatic control system realizes the core part of control. The controller receives the measurement signal from the controlled object in the closed-loop control system, generates control signals according to certain control rules to promote the actuator work, and completes the closed-loop control. It is called a regulator; the controller used in the open-loop control system is called a sequencer. The controller drives the actuator to achieve open-loop control according to a predetermined time sequence or logical condition sequence. Controllers are divided into analog regulators and digital controllers according to the signal form used. Digital controllers are further divided into sequence controllers and digital regulators. People also call the manual control mechanism a controller.

The application of controllers is not limited to the production process. Controllers are also widely used in daily life, such as timing switches for neon lights, timers for washing machines and electric fans, etc., all of which are sequence controllers.

The controller

is composed of program counter, instruction register, instruction decoder, timing generator and operation controller. It is the "decision-making mechanism" that issues commands, that is, completes coordination and direct the operation of the entire computer system.

Main functions:

Retrieve an instruction from the memory and indicate the location of the next instruction in the memory

Decode or test the instruction and generate Corresponding operation control signals to initiate specified actions;

Direct and control the direction of data flow between the CPU, memory and input/output devices.

Controller: It issues control information according to pre-given commands, so that the entire computer instruction execution process proceeds step by step. It is the nerve center of the computer.
