Description

Multisection type super frequency mainframe board and control method thereof
Technical field
The present invention relates to a kind of multisection type super frequency mainframe board and control method thereof, particularly a kind of avoiding do not caused unsettled multisection type super frequency mainframe board of system and control method thereof because of work schedule matches.
Background technology
Along with improvement of computer science, computing machine comprises CPU, motherboard, internal memory or the like, and is also more and more faster in processing and arithmetic speed, but the fast more product of relative processing speed is reflected at raising also relative on the price.Yet a product is when using, under the considering of many factors, it can't be used the limit at product, in other words, promptly be that product should have better application space, therefore, beginning the someone utilizes the technology of overclocking to make and can and make computer product can bring into play bigger usefulness with lower price.
Please refer to shown in Figure 1, with the motherboard is example, it consists predominantly of a CPU (central processing unit) 11, a sequential generation module 12, a north bridge chipset 13, and north bridge chipset 13 is provided with a Front Side Bus loop 131 at least and a fast peripheral links an interface bus loop 132 and a South Bridge chip group 14.Its action transmits sequence control signal S at least for the moment by CPU (central processing unit) 11 0To sequence generation module 12, and make sequence generation module 12 export the first clock signal CK respectively 0And the second clock signal CK 1The first clock signal CK 0Input to the Front Side Bus loop 131 of CPU (central processing unit) 11 and north bridge chipset 13, and the second clock signal CK 1The fast peripheral of input north bridge chipset 13 links interface bus loop 132 and South Bridge chip group 14.
Existing overlockin can be with the first clock signal CK in the permissible range of CPU (central processing unit) 11 0Frequency improve but need not improve the second clock signal CK 1Frequency, the first clock signal CK for example 0Can be FSB 200, FSB 201, FSB 202 even can being promoted to FSB1200 is that frequency of operation is 300MHz, but the second clock signal CK of this moment 1Still remain under the frequency of operation of PCIE 100, need be along with improving its frequency of operation.
In addition, product before Intel (Intel) 915 (Grantsdale) north bridge chipset and 925 (Alderswood) north bridge chipset, as long as the scope of overclocking is worked under the frequency that CPU (central processing unit) can bear, then as long as with the information transmission frequency overclocking between CPU (central processing unit) and the north bridge chipset, and do not need the information transmission frequency overclocking between the fast peripheral binding interface (S-PCIE-1~SPCIE-n as shown in Figure 1 and N-PCIE) of north bridge chipset and South Bridge chip group and periphery thereof, unsettled situation can not take place in system.Yet, after Intel 915 and 925 north bridge chipset, after overclocking at the first clock signal CK 0And the second clock signal CK 1The ratio of frequency of operation when surpassing certain ratio, then can produce the instability of system.
Recently, the dealer is developed the technology that another kind of overclocking again, please refer to shown in Figure 1ly, and it is with the first clock signal CK in the permissible range of CPU (central processing unit) 11 0Frequency improve simultaneously and improve the second clock signal CK according to a ratio 1Frequency, the first clock signal CK for example 0Can be FSB 133MHz, FSB 137MHz, FSB 140MHz and FSB 150MHz, the second clock signal CK of this moment 1Pairing frequency of operation is PCIE 100MHz or the above frequency of operation of PCIE100MHz.
So, though can solve at the first clock signal CK 0And the second clock signal CK 1The ratio of frequency of operation when surpassing certain ratio, cause work schedule not match, the unsettled situation of meeting generation system, but, this kind mode exists another problem, promptly be that north bridge chipset and South Bridge chip group and peripheral fast peripheral thereof link the information transmission frequency between the interface (S-PCIE-1~SPCIE-n as shown in Figure 1 and N-PCIE), one maximum value is arranged, illustrate, when the value of second clock signal is that PCIE 116MHz is when above, if first clock signal overclocking again is FSB 160MHz, and the value of second clock signal is when continue to promote surpassing PCIE 116MHz, link interface that interface be connected with fast peripheral this moment, and can't mate mutually, and then cause the instability of system at the information transmission frequency in Front Side Bus loop 131 and the transmission frequency ratio that fast peripheral links the information transmission frequency in interface bus loop 132.
From the above, because of after Intel 915 and 925 chipsets, when the ratio of the frequency of operation of first clock signal and second clock signal surpasses certain ratio, cause work schedule not match, the instability of meeting generation system, and computer product can't be brought into play its maximum efficiency.Therefore, how making computer product bring into play its maximum efficiency, is one of important topic of current motherboard overlockin in fact.
