A computer mainboard is provided, which is provided with a CPU, a north bridge chip, a south bridge chip, a sound card chip, a memory bank slot, a PCI slot, various external interfaces ad relative integrated circuit. Wherein, the south bridge chip, the sound card chip and the external interface as well as the integrated circuit are arranged under the memory bank slot; the PCI slot has only one and adopts the integrated display card chip. The utility model is compact in allocation with the mainboard size of 187 mm multiply 270 mm, which completely utilizes the internal space of a machine case to make the cubage of the machine case achieve 9 L, thus meeting the requirement of the compact machine case.

Description

Computer motherboard

Technical field

The utility model relates to a kind of computer motherboard.

Background technology

The desk-top computer mainboard of Shi Yonging generally includes ATX and two kinds of specifications of MATX in the market, and the mainboard of ATX specification has 5～6 pci expansion slots, and the size of mainboard is bigger, and standard specification is 307mm * 244mm.The mainboard of MATX specification is compared with ATX specification mainboard, and the mainboard size is less relatively, and standard specification is 244mm * 244mm.The MATX specification mainboard of common layout contains 3 pci expansion slots, South Bridge chip in the chipset is positioned at the lower left of north bridge chips, the below of longitudinal P CI slot just, and sound card integrated chip AC97CODEC is positioned at the top of longitudinal P CI expansion slot, near the position of back IO.This layout makes that the computer motherboard size is relatively large, has limited the volume of whole computer system host to a certain extent and can not accomplish can't adapt to the requirement of compact cabinet below 10 liters.

Summary of the invention

For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of computer motherboard of optimization, and the internal volume of whole computer system host is reduced, and adapts to the requirement of compact cabinet.

For realizing above-mentioned task, the utility model provides a kind of novel computer mainboard, be provided with CPU, north bridge chips, South Bridge chip, sound card chip, memory bar slot, PCI slot, various Peripheral Interface and relevant integrated circuit above it, wherein said South Bridge chip harmony the core of the card sheet is arranged at the below of memory bar slot.

Described memory bar slot below also is provided with basic input/output bus, audio interface and USB interface and relevant control circuit.

In the reality, above-mentioned PCI slot is one.

And the utility model computer motherboard adopts integrated video card chip.

Because the utility model has changed the MATX specification mainboard of common layout, South Bridge chip, the sound card chip, basic input/output bus, USB interface and audio interface and relevant integral control circuit are arranged at the memory bar slot below of computer motherboard, replace the video card slot with integrated video card chip, and the PCI slot reduced to one, like this by changing the layout of former MATX specification mainboard, make the size of mainboard be reduced to 187mm * 270mm from the standard size 244mm * 244mm of MATX specification mainboard, laterally the part of reduction is that power supply has been reserved the space, vertically the part that increases can be inserted the hard disk rack below easily, thereby can more make full use of the cabinet inside space, make the internal volume of total system be reduced under common MATX specification mainboard and be beyond one's reach 9 liters, adapt to the requirement of compact cabinet.

Embodiment

Referring to Fig. 1 a and b, Fig. 1 a has shown the layout of common MATX specification computer motherboard.In order more to clearly demonstrate each position component relation on Fig. 1 a, define the reference coordinate of Fig. 1 a with Fig. 1 b, with the x direction of principal axis shown in Fig. 1 b serves as horizontal, the positive dirction of x axle is right-hand, the y direction of principal axis is vertically, and y axle positive dirction is the top, is example with the memory bar slot 12 of computer motherboard among Fig. 1 a, memory bar slot 12 long side directions are the x direction of principal axis, and memory bar slot 12 short side directions are the y direction of principal axis.The MATX specification computer motherboard of Fig. 1 a contains 3 PCI slots 1, South Bridge chip 2 in the chipset is positioned at the lower left of north bridge chips 3, integrated sound card chip 4 is positioned near the A pilot hole 5, position near input and output (IO) interface 6, Basic Input or Output System (BIOS) (BIOS) bus 7, audio interface 8 and USB interface 9 are positioned at the lower left corner of mainboard, mainboard central authorities are AGP video card slot 10, north bridge chips 3 and CPU11, be memory bar slot 12 below, the below is hard disk floppy drive interface 13 and ATX power interface 14.

Referring to Fig. 2 a and b, Fig. 2 a has shown the layout structure of the computer motherboard of implementing according to the utility model.Same can clearly demonstrate more that each position component concerns Fig. 2 a on, define the reference coordinate of Fig. 2 a with Fig. 2 b, with the x direction of principal axis shown in Fig. 2 b serves as horizontal, the positive dirction of x axle is right-hand, the y direction of principal axis is vertically, and y axle positive dirction is the top, is example with the memory bar slot 2 of computer motherboard among Fig. 2 a, memory bar slot 2 long side directions are the x direction of principal axis, and memory bar slot 2 short side directions are the y direction of principal axis.Essence of the present utility model is on the basis of MATX specification computer motherboard, below mainboard, increased a regional A again, reduced a part of area B in left side simultaneously, reduced the chip and the interlock circuit thereof that relate in the area B and move to newly-increased regional A, chip layout is constant substantially in other zone.Wherein South Bridge chip in the chipset 1 and integrated sound card chip 3 are positioned at the below of memory bar slot 2, Basic Input or Output System (BIOS) (BIOS) bus 4, audio interface 5 and USB interface 6 also are positioned at newly-increased zone, the below of memory bar slot 2, the utility model has replaced former AGP video card slot with integrated video card chip 7, because computer motherboard of the present utility model adopts integrated chip more, utilize the external unit of PCI slot less, PCI slot 8 has only one.Wherein input and output (IO) interface 9, north bridge chips 10, CPU11 and memory bar slot 2 and interlock circuit etc. keep former MATX placement position constant substantially.So just make the mainboard size be reduced to 187mm * 270mm by the 244mm * 244mm of MATX specification, laterally the part of reduction is that power supply has been reserved the space, vertically the part that increases can be inserted into the hard disk rack below, do not take new space in addition, reach and make full use of the computer host system inner space, make the internal volume of cabinet reach MATX specification computer motherboard and be beyond one's reach 9 liters, adapt to the demand of compact cabinet.

Fig. 3 a is a specific embodiment of the utility model computer motherboard, same can clearly demonstrate more that each position component concerns Fig. 3 a on, define the reference coordinate of Fig. 3 a with Fig. 3 b, with the x direction of principal axis shown in Fig. 3 b serves as that laterally the positive dirction of x axle is right-hand, and the y direction of principal axis is vertical, y axle positive dirction is the top, memory bar slot 2 with computer motherboard among Fig. 3 a is an example, and memory bar slot 2 long side directions are the x direction of principal axis, and memory bar slot 2 short side directions are the y direction of principal axis.There is a PCI slot 8 in the z upper left corner of present embodiment, and the centre is north bridge chips 10 and CPU11, is memory bar slot 2 below, and there is South Bridge chip 1 harmony the core of the card sheet 3 and various Peripheral Interface and interlock circuit the below of memory bar slot 2.In the present embodiment, the sound card integrated chip that computer motherboard adopts is AC97 CODEC, and video card adopts integrated INTEL 865G chipset.
