Detailed ways

FIG. 1 shows the structure diagram of the computer motherboard with automatic adjustment of hardware parameter values according to the present invention. For the convenience of disclosing the present invention and the purpose of being easy to understand, in Fig. 1, computer mainboard 10 only draws the hardware assembly directly related to the present invention, yet these other these assemblies that belong to computer mainboard 10 have nothing to do with the present invention If they are directly related, drawing of these other components is omitted. The computer mainboard 10 of the present invention is also the same as the known computer mainboard, and can know the specifications of these hardware components arranged on the computer mainboard, such as: CPU type (Type), DDR memory type, DDR2 memory type and the like. Similarly, the computer motherboard 10 of the present invention is also the same as the known computer motherboard, that is, it can automatically set the factory settings (Default) of these hardware components at corresponding to these hardware components. However, for the purpose of over-frequency use or energy-saving use, the computer motherboard 10 of the present invention is automatically switched on and off at least once, and the frequency of the front side bus will be automatically changed every time the computer is switched on and off, so as to find out the frequency that meets the requirements of the computer motherboard 10. The values of these hardware parameters in the operating mode of overclocking or energy saving under the current hardware environment conditions.

The computer motherboard 10 of the present invention at least includes: a watchdog unit 101, a frequency generator 102, a hardware parameter value setting unit 103, and a storage element 104, which are now described as follows.

The watchdog unit 101 is connected to the frequency generator 102 . One of the functions of the watchdog unit 101 is to automatically generate a signal 101 a and transmit it to the frequency generator 102 to notify the frequency generator 102 after a predetermined time has elapsed. Another function of the watchdog unit 101 is to automatically generate a restart signal 101b after the predetermined time has elapsed, so that the computer motherboard 10 can be automatically shut down and then restarted. After the watchdog unit 101 automatically starts timing (or counting), the watchdog unit 101 generates a signal 101a. The specific implementation means of the watchdog unit 101 can adopt related existing technologies such as a known counter (Counter) or a known timer (Timer). An example of the time length of the above-mentioned predetermined time is, for example, adopting from when the computer is turned on to when the Windows operating system (such as Windows OS).

One of the functions of the frequency generator 102 is to generate a frequency, and N times of this frequency, N>0, (for example, 3 times of frequency, 3.5 times of frequency, 4 times of frequency, 5 times of frequency...etc.) can be used as The internal frequency of the CPU. The internal frequency is the internal operating frequency of the CPU. For example, for a 3GHz CPU, 3GHz is the internal frequency. The frequency value generated by the frequency generator 102 can be set by the hardware parameter value setting unit 103 . For example, the hardware parameter value setting unit 103 sets the frequency generator 102 so that the frequency generator 102 generates a frequency of 333Mhz. In addition, the hardware parameter value setting unit 103 can set the operation mode of the frequency generator 102 as a decreasing frequency mode or an increasing frequency mode. At the same time, the hardware parameter value setting unit 103 can set the frequency generator 102 to decrease The value of frequency ΔF1 and the value of increment frequency ΔF2. Another function of the frequency generator 102 is to receive the signal 101a transmitted by the watchdog unit 101. Then, the frequency generator 102 automatically converts the frequency generated at present, according to the current mode of operation, it belongs to the decreasing frequency mode or increasing frequency mode, and Decrease or increase the current frequency to generate a new frequency, and output the new frequency. For example, the generated frequency before receiving the signal 101a is 333Mhz, after receiving the signal 101a, if the frequency generator 102 is in the decreasing frequency mode, the 333Mhz frequency is subtracted by ΔF1 to obtain a new frequency less than the 333Mhz frequency (for example, 300Mhz ); and for example, the generated frequency before the received signal 101a is 333Mhz, after the received signal 101a, if the frequency generator 102 is in the incremental frequency mode, then the 333Mhz frequency is added to the ΔF2 to obtain a new frequency greater than the 333Mhz frequency (eg 366Mhz). Then, output this new frequency (eg 300Mhz or 366Mhz).

The restart signal 101b can also be automatically generated by the frequency generator 102 instead.

The specific implementation means of the frequency generator 102 can directly adopt related known frequency generator technology.

Furthermore, the watchdog unit 101 and the clock generator 102 can be integrated into a single integrated circuit (IC).

The function of the storage element 104 is to store multiple sets of hardware parameter values. These groups of hardware parameter values can be pre-stored before the computer motherboard 10 leaves the factory. Due to the various combinations of these hardware components that the computer motherboard 10 is equipped with, such as the combination of CPU types and memory types, each combination will have hardware parameter values for overclocking and super (electrical) voltage upper limits, as well as frequency reduction and For the hardware parameter value of the lower limit of use (voltage), the storage element 104 can be used to store the hardware parameter value of the upper limit of use and the hardware parameter value of the lower limit of use of these combinations. Another function of the storage element 104 is to record and store the hardware parameter values successfully obtained by the computer mainboard 10 after several times of power on and off. The specific implementation means of the storage element 104 can directly adopt a flash memory, for example.

When the computer motherboard 10 is turned on for the first time, the computer motherboard 10 can use the parameter values set by the hardware manufacturer to start the computer.

Please refer to FIGS. 2A-2C for the operation flow 20 of the computer motherboard 10 of the present invention. Step 201 is to determine whether the user executes the function to automatically adjust the hardware parameter value. The specific means for realizing step 201 can be adopted in the following three ways. The specific implementation components of the hardware parameter value setting unit 103 can be realized by the basic input output system (BIOS) of the computer motherboard 10 or application programs. To allow the computer motherboard 10 to be required to perform the function of automatically adjusting hardware parameter values, one of the following three methods can be adopted. Give the BIOS 103 as a specific embodiment description now. The first method is: the user can make a choice through the setting screen of BIOS 103, the user enters the setting screen of the function of automatically adjusting the hardware parameter value, and then enables (Enable) this function, and then the user selects Specify one of the automatic hardware parameter value adjustment functions for overclocking and overvoltage, or the automatic hardware parameter value adjustment function for frequency reduction and voltage reduction. The second method is: on the panel of the computer case, the function button for automatically adjusting the hardware parameter value of overclocking and over (electricity) voltage and the function button of automatically adjusting the hardware parameter value for frequency reduction and lower (electricity) voltage are set, and then the BIOS 103 decides which function to execute according to the pressing signals of the two buttons. The third method is: under the Windows operating system, execute the application program 103 that starts the function of automatically adjusting the hardware parameter value.

Please refer to step 202, after the user finishes selecting which function to automatically adjust the hardware parameter value, the BIOS 103 will record the selected function item. The BIOS 103 can record the selected function items in the storage element 104.

Please refer to step 203, if the user chooses to perform the function of automatically adjusting the hardware parameter value of overclocking and overvoltage (electricity), then BIOS 103 reads from the storage element 104 the one group of information that meets the current hardware conditions of the computer motherboard 10. Using the upper limit hardware parameter values, then, the BIOS 103 sets the set of upper limit hardware parameter values to the corresponding hardware components. For example, the BIOS 103 sets the frequency generator 102 to specify the generated frequency, and this frequency is used as the starting (Start) frequency of the frequency generator 102, and is set to specify the decreasing frequency mode and the decreasing frequency ΔF1 value; The optional (Optional) setting of the voltage integrated controller 105 is to specify the generated CPU voltage value; the optional (Optional) setting of the memory controller of the north bridge chip 106 by the BIOS 103 is set to specify the memory clock; the BIOS 103 orders the watchdog unit 101 started to operate. On the other hand, if the user chooses to perform the function of automatically adjusting hardware parameter values for frequency reduction and voltage reduction, then the BIOS 103 reads from the storage element 104 a set of values that meet the current hardware conditions of the computer motherboard 10. Using the lower limit hardware parameter values, the BIOS 103 sets the set of lower limit hardware parameter values to the corresponding hardware components. Since the setting method of the frequency generator 102 is different from the above, it will be specifically described. The BIOS 103 sets the frequency generator 102 to specify the generated frequency, which is used as the starting (Start) frequency of the frequency generator 102, and is set to specify the incremental frequency mode and the incremental frequency ΔF2 value.

Then, the BIOS 103 enables the watchdog unit 101 to start, and the computer mainboard 10 is restarted.

Two situations can take place in the computer main board 10 of rebooting, and the first kind of situation is: computer main board 10 can't start and crashes (Hang) under that group of hardware parameter values that just was set. The second situation is: the computer main board 10 can be successfully booted normally under the set hardware parameter value just now. If the computer mainboard 10 is shut down due to the first situation, the watchdog unit 101 will generate signals 101a and 101b respectively after reaching a predetermined time. After receiving the signal 101a, the frequency generator 102 decreases the current frequency by ΔF1 or increases by ΔF2 according to the current operating mode (decreasing frequency mode or increasing frequency mode) to generate a new frequency to replace the previous frequency. After the computer motherboard 10 receives the signal 101b, it automatically restarts again. However, the computer motherboard 10 restarted this time is set under the hardware environment of the new frequency to restart the computer. The watchdog unit 101 automatically re-times (or counts).

The computer main board 10 that is restarted under the hardware environment of the new frequency is set, similarly, the above two situations will also occur. If the first case occurs again, similarly, the frequency generator 102 decreases the current frequency by ΔF1 or increases by ΔF2 to generate a new frequency to replace the previous frequency. The mainboard of the computer 10 is set again under the hardware environment of the new frequency to restart the computer. This is repeated until the above-mentioned second situation occurs on the mainboard of the computer 10 .

If the computer motherboard 10 takes place in the second situation and successfully boots up, at this moment, the computer motherboard 10 must disable (Disable) the function of timing (or counting) of the watchdog unit 101, and prohibit the watchdog unit 101 from generating a signal 101a, 101b. Furthermore, the mainboard of the computer 10 can also record the new frequency value that can be turned on successfully in the storage element 104 .

The program code that is used to implement the second situation can be a driver program or become a part of the program code of the BIOS 103. After the mainboard 10 of the computer is started successfully and the Windows operating system is loaded, the call (Call) of the Windows operating system is used to call and execute the driver program or the part of the program code of the BIOS 103.

Furthermore, the computer mainboard 10 can reuse the new frequency value that can be started successfully as the start frequency of the frequency generator 102, restart the watchdog unit 101, and execute step 203 again. In this way, it is possible to obtain another new frequency value that can be turned on successfully. After repeating this many times, it is possible to obtain multiple sets of the new frequency values that can be turned on successfully.

Furthermore, the operation process 20 executed by the computer motherboard 10 can be further matched with various changes in the voltage value of the CPU and various changes in the voltage value of the main memory (such as DDR, DDR2). For example, the CPU voltage value is specified through the setting of the memory controller of the computer mainboard 10 and the voltage integrated controller of the computer mainboard 10 . Under the combination of these changes, let the mainboard 10 of the computer be tested one by one of the operation process 20, so that the mainboard 10 of the computer can automatically obtain the mainboard 10 of the computer under the operation of overclocking and super (electrical) voltage, which overclocking The combination of these hardware parameter values with the over (electrical) voltage still enables the computer motherboard 10 to be started successfully. In the same way, the computer main board 10 can automatically obtain the computer main board 10 under the operation of frequency reduction and voltage reduction (electricity), and which combinations of these hardware parameter values for frequency reduction and voltage reduction (electricity) can still make the The mainboard of the computer 10 is turned on successfully.

From among the multiple combinations of these hardware parameter values that allow the computer mainboard 10 to be turned on successfully, the computer mainboard 10 can further easily select the best energy-saving combination that allows the computer mainboard 10 to be successfully started, or select the best energy-saving combination that allows the computer mainboard 10 to start successfully. A combination of maximum overclocking and overvoltage for a successful boot.

Those skilled in the art who apply the computer mainboard 10 of the present invention can further develop an application program. The function of this application program can also be combined with these hardware parameter values except being able to display multiple combinations of the above-mentioned hardware parameter values that can be started successfully on the screen. Multiple combinations of hardware parameter values are classified, for example, classified into: classification of extreme energy saving combinations, classification of extreme overclocking combinations, classification of safe energy saving combinations, classification of safe overclocking combinations, and so on. After the user selects a combination under one of the classifications, the application program immediately sets the hardware parameter values of the combination in the corresponding hardware components, thus further enhancing the value of the computer motherboard.

The computer motherboard of the present invention has the ability to automatically adjust hardware parameter values, and can automatically achieve the purpose of overclocking or energy saving. , and then continue to perform overclocking or energy-saving operations, this feature is the advantage and greatest feature of the present invention.

However, what is described above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. Those skilled in the art can obviously make changes and modifications, which should be regarded as not departing from the essence of the present invention. .
