Description
[Ji Intraoperative field]
The relevant a kind of CPU frequency multiplying method of the present invention, particularly relevant for a kind of intelligent CPU frequency multiplying method, it has CPU overclocking program in BIOS, can be provided with automatically the hardware and software of system stable operation parameter is provided by carrying out this CPU overclocking program.
[Bei Jing Ji Intraoperative]
Along with the fast development of PC, about the information of computing machine overclocking, be seen everywhere in the books and periodicals, around our life, is no lack of the existence that some overclocking fans and DIYER are arranged even on the net.What is an overclocking so actually? strictly speaking, overclocking is a generalized concept, it is meant a certain parts frequency of operation of any raising computing machine and makes it to be operated in behavior and relevant action under the non-standard frequency, comprising a lot of parts of CPU overclocking, mainboard overclocking, internal memory overclocking, display card overclocking and hard disk overclocking or the like, and the frequency of operation of the overclocking of the narrow sense indication so-called raising CPU that is exactly most of people.In the English, overclocking is " OverClock ", is also write a Chinese character in simplified form into OC, and overclocking person is exactly " OverClocker ", its translation meaning of coming is the clock frequency that surmounts standard, and therefore external friends also think and allow the hardware product be overclocking with the frequency work that surmounts standard.
In the ordinary course of things, the dot frequency leeway that CPU manufacturer all can reserve in order to guarantee product quality, the for example actual P4CPU that can reach 2GHz may a nominal become 1.8GHz to sell, and therefore utilizes the retaining space of this point point cpu frequency just to become the initial overclocking purpose of part hardware fans.
The working clock frequency of CPU (dominant frequency) is by two parts: outer frequently deciding with frequency multiplication, both products are exactly dominant frequency.So-called foreign frequency, what refer to is exactly whole system bus frequency, and it is not equal to the frequency of the FSB (Front Side Bus) that often hears, but by the unique frequency that determines FSB of outer frequency---FSB is the bus that connects CPU and north bridge chips.The full name of frequency multiplication is a Clock Multiplier Factor, exists a ratio relation between the clock frequency of CPU and the outer frequency, and this ratio is exactly Clock Multiplier Factor.Frequency multiplication is the numeral based on natural number, 0.5 to be the interval, and 11.5,12,13 these classes for example, the highest frequency multiplication nearly can reach 25 now.Multiply by 21 frequency multiplication such as P4 2.8G CPU by the outer frequency of 133MHz obtains.
Overclocking overall, be exactly outer frequency and the frequency multiplication of manually removing to be provided with CPU, so that CPU is operated under the higher frequency, yet the CPU frequency multiplication of Intel all is locked now, and AMD AthlonXP the product of counting is also only arranged seldom is not lock frequency multiplication, therefore present overclocking great majority all are to go overclocking above outer frequency, and this multiplicand of frequency that just improves external bus is improved the dominant frequency of CPU.
Present mainboard manufacturer has much all made the overclocking capabilities of hommization, thus the method for overclocking also from before hard overclocking become present more convenient simpler soft overclocking.So-called hard overclocking is meant and manually is provided with frequently outer and operating voltage such as CPU, internal memory realize by wire jumper above the mainboard or DIP switch, and parameters such as frequency, frequency multiplication and each several part voltage outside being provided with inside the BIOS that soft overclocking refers in system, some mainboard manufacturers also released overclocking capabilities (for example red storm RedStrom of SOLTEX) be exactly mainboard can be that unit progressively improves outer rate again and again automatically with 1MHz, automatically for the user finds one to allow the highest frequency that CPU can stable operation, this is a kind of overclocking of foolization robotization.
Yet, though above-mentioned frequency multiplying method can make system obviously promote serviceability, but also there are many defectives, for example: adopt hard overclocking then must understand very much to hardware, this is all not too suitable to most of people, even be familiar with hardware and also be just getting by continuous test, repeatedly research, not only time-consumingly overtax one's nerves, and also relatively also higher to the degree of damage of hardware; On the other hand, adopt above soft frequency multiplying method no doubt can save trouble much, but require the user to select related hardware model and parameter (in the majority with software under the Windows environment especially) sometimes, though and progressively improve with test macro whether stablize the method fool who seeks highest frequency with the subsection frequency, but it is still comparatively loaded down with trivial details carry out, and this highest frequency differs and is decided to be the most stable frequency usable range.
In view of this, be necessary to provide a kind of intelligent CPU frequency multiplying method in fact, make system works stable to seek an overclocking frequency that is fit to.
[summary of the invention]
In view of above reason, fundamental purpose of the present invention is to provide a kind of intelligent CPU frequency multiplying method, and this method is tested the stability of system hardware in the process that the CPU overclocking is handled, to guarantee that the system after the overclocking can steady operation.
For achieving the above object, a kind of intelligent CPU frequency multiplying method of the present invention can be implemented by following steps: it is provided with a CPU overclocking handling procedure in BIOS, click this overclocking option switches, CPU can be to the stability of current FSB (Front Side Bus) frequency values test macro, but thereby judge whether overclocking of this system, but and when prompting for overclocking, systematic clock generator is carried out initialization, and obtain the frequency values of current FSB, by adjusting clock generator, FSB frequency values (being the outer frequency of CPU) that can corresponding adjustment CPU makes it increase different numerical value one by one, adjust relevant parameter simultaneously, as voltage, cooperating overclocking, thereby look for out a preferable overclocking frequency values that is applicable to current system, should preserve among the CMOS RAM by preferable overclocking frequency values, and with this frequency restarting systems.This frequency multiplying method has been simplified the complicated processes of overclocking in the past, makes overclocking intelligent, more convenient to operate more.
Compared to prior art, the invention provides a kind of intelligent CPU frequency multiplying method, its in the BIOS stored in order to carry out the program that intelligent CPU overclocking is handled, when this intelligent CPU overclocking program is carried out, not only improve the FSB frequency values of CPU, and detect the stability of peripheral hardware equipment simultaneously, when obtaining an available frequency range, therefrom select a suitable frequency value to carry out overclocking, and after overclocking, adjust other hardware and software relevant parameters to cooperate the execution of overclocking.
For making purpose of the present invention, structural attitude and function thereof there are further understanding, cooperate diagram to be described in detail as follows now:
[description of drawings]
Fig. 1 is the CPU overclocking handling procedure process flow diagram of the intelligent CPU frequency multiplying method of the present invention.
Fig. 2 is the process flow diagram of the implementation that steps A comprised among Fig. 1.
Fig. 3 is the process flow diagram of the implementation that step B is comprised among Fig. 1.
[embodiment]
See also shown in Figure 1ly, be the CPU overclocking handling procedure process flow diagram of the intelligent CPU frequency multiplying method of the present invention.The user is when starting booting computer, as desire to enter the setting picture of BIOS so that when carrying out the CPU overclocking and setting, all can enter the setting program interface of the relevant configuration of BIOS under most of situation by [DEL] key on the lower keyboard or [F2] key, in step 100, the user enters BIOS and sets picture, and this BIOS sets in the picture, is the parameter setting that comprises the configuration driving of input/output device and each peripheral unit, comprising overclocking handling procedure of the present invention, then carry out step 101.
In step 101, the user carries out configuration and setting by input interface, enters the CPU overclocking and handles picture, then carry out step 102.
In step 102, when CPU received the instruction that the user transmits by input interface, this CPU carried out initialization to clock generator, then carry out step 103.
In step 103, CPU obtains the current FSB frequency values of CPU from BIOS ROM, then carry out step 104.
In step 104, by the FSB value of CPU is constantly raised, and on the basis of each FSB frequency values test macro stability, if the system stability property testing passes through, just think that this value is a preferred values, and with itself and this moment each hardware parameter value be stored in the CMOS RAM, then carry out step 105.
In step 105, the FSB frequency values that CPU will be stored in the CMOS RAM writes in the clock generator, then carry out step 106.
In step 106, the CPU restarting systems, then system promptly finishes CPU overclocking handling procedure thus with this FSB frequency values normal boot-strap.
This overclocking handling procedure and previous soft/difference of hard overclocking mode is, this method does not need to look for out the highest FSB frequency values that is fit to the native system running, and be to provide a kind of method, look for a preferable overclocking frequency at this highest FSB frequency values one in more among a small circle, and the method applied in the present invention to look for speed fast, greatly reduce the time of waiting.Because the frequency that CPU uses is high more, then the speed that computer is aging is also accelerated, but when we adopt one during near the frequency of this highest frequency value, its effect is more or less the same, but generally speaking fiduciary level is improved.
On the other hand, because the software that system loads in bios program is fewer, therefore the test to software is not easily, therefore here based on hardware testing, the overall tendency of the increasing degree of the increasing degree of cpu temperature, hard disk temperature and rotation speed of the fan etc. for example, with the stability of judging system how.
See also shown in Figure 2ly, it is the process flow diagram of step 101 among Fig. 1 to the implementation that (is labeled as A) between the step 2 and is comprised.Be similar to other setting option under the BIOS, CPU overclocking handling procedure is defaulted as normal operating condition but not the overclocking treatment state.After carrying out this overclocking handling procedure, at first in step 1010, to current FSB frequency values test macro stability, the result of this test is exported to step 1012, but judge whether overclocking (stability of system directly have influence on overclocking could) according to this test result by step 1012, but during as if overclocking, can enter and execution in step 1014; Otherwise carry out step 1018.
In step 1014, by input interface (as keyboard etc.) input (as Y or N), if when the user imports Y, then CPU begins to carry out the overclocking handling procedure after receiving this instruction, enters the processing of the step 102 in step 1016 execution graph 1 by the user; If the user when importing N, does not then carry out, and carry out step 1018, withdraw from otherwise carry out step 1018, and can carry out BIOS set in the setting of other configuration handle, dispose and can after preserving relevant information, withdraw from the BIOS setting program.
See also shown in Figure 3, the implementation process flow diagram that is comprised for (being labeled as B) between step 104 and the step 105 among Fig. 1, it is used to look for out a preferable FSB frequency values that can make system stable operation.
At first, in step 1040, store this FSB frequency values and other related hardware parameters in CMOS RAM, but this step then carry out step 1041 in order to write down the overclocking frequency values of the follow-up steady operation of looking for.
In step 1041, this current FSB frequency values is increased XMHz, then carry out step 1042.Wherein there is a system default value in this X value, and general recommendation size is 100--500.
In step 1042, adjust the core voltage of CPU and other relevant system parameters (as the revolution of fan etc.) according to the frequency values after the above-mentioned setting, it can be mated, then carry out step 1043.
In step 1043, CPU judge system and peripheral hardware device whether can be under this new FSB frequency steady operation, if when this peripheral unit can be stablized running, carry out step 1044; Otherwise carry out step 1048.
In step 1044, judge whether X＜Y sets up, if carry out step 1045; Otherwise carry out step 1046.Wherein this Y value is made by oneself by system, and general optional scope is 5-50.
In step 1045, earlier current frequency values is write among the CMOS RAM, continue the step 105 in the execution graph 1.
In step 1046, continue to judge whether Z ≠ 0 sets up, if carry out step 1047; Otherwise return above-mentioned steps 1040.Wherein the Z value unsettled number of times occurs in order to system after writing down each renewal FSB frequency, and the initial value of Z is 0.
In step 1047, the X value is kept to half of currency, being finished turns back to above-mentioned steps 1040.
In step 1048, the X value is kept to half of currency, and the Z value is increased by 1, then be back to step 1041.
Below be cutline, and enumerate an example and analyzed above-mentioned steps.At first be pointed out that, the purpose of this flow process is to seek a preferable frequency values that is applicable to current system, for achieving the above object, its FSB frequency values to current system increases XMHz one by one, the Adjustment System correlation parameter can mate it with the frequency values after this increase, test system hardware stability at this moment, if system's operation is normal, show that this overclocking frequency can use, but our the optimum frequency value that will look for not necessarily, therefore can continue current system frequency value is increased XMHz one by one, and carry out associative operation; Show that then the frequency values of this moment is too high if wild effect occurs, need suitably to reduce that we can be kept to X previous half, and the second value is added 1, repeat once above-mentioned operation more here, continue the test system stability performance of this moment again.Certainly, iff being to go back imperfection like this, we can specify a small range, and what fall into this we just think gained after more among a small circle when the value of last X is exactly the frequency values that we will look for, but because the frequency in this scope all is an operate as normal.
For making explanation clearer, we can set X=100, Y=10, and current FSB frequency is 133MHz, owing to be to carry out for the first time, so also be 133MHz among the CMOS RAM, make the system can not steady operation if increase 100MHz, X=50 then, Z=1, increase 50MHz this moment on the basis of 133MHz, promptly with the frequency work of 183MHz, if still can not make system stability work, then X=25, Z=2, be frequency work at this moment with 158MHz, test shows energy steady operation, explanation can be stablized overclocking, but work is not also finished, because have X greater than Y this moment, therefore continue to make X=12 (we round numerical value) here, in CMOS RAM, preserved the frequency values 158MHz of steady operation this moment simultaneously, whether the frequency that after this need test 170MHz can make system stability work, if can not, continuing has X=6, Z=3, at this moment the FSB frequency values is 164MHz, test is for can steady operation, then in step 1044 owing to satisfy X=6＜Y=10, can jump out this flow process this moment, but need before this this FSB frequency values is saved among the CMOS RAM, continue step 105 in the execution graph 1 then.And for current with the situation of frequency 133MHz overclocking to 166MHz, we can be set at 164MHz, its difference is little, if wish more approachingly, the Y value suitably can be dwindled.
Compare with the previous method that increases the 1MHz frequency according to this, this invents employed method can not only look for out a preferable overclocking frequency values fast, shorten the time look for, and this method do not need to find out the highest frequency values, but can estimate the frequency range at its place.
