DETAILED DESCRIPTION

[0020] The overall idea of ​​the technical solution provided by the utility model is as follows:

[0021] See also Figures 1 to 4 , a mainboard, comprising:

[0022] The main body 100 of the motherboard adopts an ATX board type. The main body 100 of the motherboard is provided with a CPU slot 200, a power interface 300 and an MCIO interface 400. The CPU slot 200, the power interface 300 and the MCIO interface 400 are connected by wires, wherein the CPU slot 200 adopts an AMD GENOA SP5 slot, the power interface 300 is used to connect to a power module, and the 5V standby voltage line and the 5V main voltage line of the power module are connected to the 5V auxiliary power line of the main body 100 through a switching circuit 310, and the MCIO interface 400 is connected to the CPU slot 200 through a clock buffer 500.

[0023] The embodiment of the utility model adopts an ATX-type motherboard body 100, which can be placed in any chassis that meets the ATX standard size. In addition, the ATX-type motherboard is smaller in size, occupies less space, and can be placed better. By using the power interface 300 to connect the power module and directly using the power of the power module, the mainboard DC-DC conversion module can be reduced. In addition, for the 5V auxiliary power line used by the mainboard, since the current provided by the 5V standby voltage line of the power module is limited, we have added a switching circuit 310. For example, when the mainboard is in standby mode, the 5V auxiliary power is switched from the switching circuit 310 to the 5V standby voltage line; when the mainboard is in the power-on state, the 5V auxiliary power is switched from the switching circuit 310 to the 5V main voltage line. This design fully considers the power demand of the mainboard under different working conditions, so that the mainboard can flexibly switch the power supply according to actual conditions, which helps to ensure the stable operation of the mainboard under various working conditions; by adopting the AMD GENOA SP5 slot, the mainboard can support the latest AMD GENOA series CPU, and the AMD GENOA series CPU supports the integration of all PCI E / SATA / USB interfaces into the CPU, without the need for additional PCH or other conversion chips, which is more cost-effective; in addition, the PCI E 100M clock on the mainboard can basically use AMD The native clock of the GENOA series CPU reduces the additional clock source, freeing up more space on the motherboard and making the motherboard design more compact; see Figure 4 This design also introduces a clock buffer 500 (clock BUFFER) to provide a 100M clock to the MCIO interface 400. Since the environment in which the MCIO is located usually operates at a higher frequency, the signal is easily attenuated in a high-frequency environment. The clock buffer 500 can amplify the clock signal from the CPU to prevent signal attenuation during transmission and maintain a strong signal.

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Preferably, the switching circuit 310 includes a PMOS device and an NMOS device, a first side of the PMOS device and the NMOS device is connected to the power interface 300, and a second side of the PMOS device and the NMOS device is connected to the 5V auxiliary power line. For details, see Figure 3The power interface 300 can be composed of 1 ATX 24PI N+2 ATX 8PI N terminals. In the figure, P5V_SB is a 5V standby voltage line, P5V_SYS is a 5V main voltage line, and the mainboard 5V AUX device is a device that uses a 5V auxiliary power line on the mainboard. For example, when the control signal is logic high (or a certain condition is met, such as the CPU is in a dormant state), the PMOS device is turned on, so that the 5V standby voltage line is connected, and power is provided to the mainboard 5V auxiliary power line, while the NMOS device is in a cut-off state. Conversely, when the control signal is logic low (or a certain condition is met, such as the CPU is actively operating), the NMOS device is turned on, the 5V main voltage line is connected, and power is provided to the mainboard 5V auxiliary power line, while the PMOS device is in a cut-off state. In this way, the switching circuit 310 realizes automatic switching between standby power and regular power according to the control signal or system state, thereby optimizing power management and improving power efficiency.

[0026] For further information, see Figure 2 , the mainboard body 100 is also provided with a DDR5 memory slot 600, which is connected to the CPU slot 200. DDR5 (Double Data Rate 5) memory is the latest generation of RAM technology standard. Compared with the previous generation DDR4, DDR5 memory provides a higher data transfer rate and a larger capacity, while also achieving lower power consumption. While meeting the processing speed requirements of modern computers, DDR5 memory also reserves space for future technological development. The DDR5 memory slot 600 is designed on the mainboard body 100 and is connected to the CPU slot 200 through a wire. Such a design ensures that the CPU can read and write data from the memory at the highest data transfer speed, thereby improving the operating efficiency of the entire system. At the same time, due to the small size and high speed of DDR5 memory, the mainboard will be able to provide strong support for high-performance applications that require a lot of computing and data processing, such as servers, large data centers, AI and machine learning. Preferably, there are 12 DDR5 memory slots 600.

[0027] For further information, see Figure 2 A SATA connector 700 is also provided on the mainboard body 100, and the SATA connector 700 is connected to the CPU slot 200. The direct connection between the SATA connector 700 and the CPU slot 200 allows data to be transmitted between the SATA device and the CPU more directly and efficiently, avoiding the circuitous transmission of data between mainboards and improving the overall operating efficiency of the system. In addition, SATA (Serial ATA) is a computer hard disk interface used to connect a host bus adapter and mass storage devices such as hard disk drives and optical disk drives.

[0028] More preferably, the motherboard body 100 is designed with three SFF-8643 SATA connectors 700, each of which supports the connection of four SATA devices, and can support a total of 12 SATA devices. This provides users with a wealth of hard disk expansion options, and can meet users' needs for large amounts of high-speed storage without the need for an external memory card.

[0029] Furthermore, the MCIO interface 400 is a PCI E5.0 MCIO interface 400, and the clock buffer 500 is a clock buffer 500 supporting PC IE5.0. PCI e 5.0 is the latest slot technology, and the maximum supported data transmission speed can reach 32.0GT / s, which is double the 16GT / s data transmission rate of PCI e 4.0. It not only provides the ability to connect high-speed devices (such as graphics cards, network cards, NVMe SSDs, etc.), but also reserves sufficient bandwidth for future devices. The MCIO interface 400 uses PC I E5.0 technology, which can provide high-bandwidth and low-latency data transmission capabilities for devices connected to the MC IO interface 400, and optimize device performance. In addition, the clock buffer 500 of PC I E5.0 can provide an accurate clock signal for the MCIO interface 400. It helps to maintain a strong signal, reduce signal attenuation in a high-frequency environment, and ensure the accuracy of data transmission.

[0030] For further information, see Figure 2 , the motherboard body 100 is also provided with a PCI E5.0 X16 slot 800, which is connected to the CPU slot 200. The bandwidth provided by the PCI e 5.0x16 slot 800 greatly exceeds that of previous versions, greatly improving the data transmission speed, which is crucial for deep learning, high-performance computing, VR and other applications requiring high bandwidth and low latency. The design of direct connection between the PC I e 5.0x16 slot 800 and the CPU slot 200 makes data transmission between the CPU and various devices (such as graphics cards, audio cards, SSDs, etc.) more direct and efficient, greatly reducing the delay of data transmission and improving system performance.

[0031] For further information, see Figure 1The mainboard body 100 is also provided with a BMC management chip 900, which is connected to the CPU slot 200. Specifically, the BMC (Baseboard Management Controller) is a management controller that specifically processes server hardware, allowing users to remotely monitor and manage the status of server hardware through the network without starting the operating system. The mainboard body 100 is provided with a design in which the BMC management chip 900 is directly connected to the CPU slot 200, which allows the CPU to directly receive and respond to the instructions of the BMC, speeding up the processing speed of the control instructions and improving the efficiency of server management. At the same time, the BMC management chip 900 can also monitor the working status of the server hardware in real time, including temperature, voltage, fan operating status, etc. Once an abnormality is found, it can actively send an alarm and try to repair it, ensuring the stable operation of the server.

[0032] For further information, see Figure 1 The mainboard body 100 is also provided with a BMC management network port 910, which is connected to the BMC management chip 900. The BMC management network port 910 allows the administrator to connect to the BMC management chip 900 through the network. Through the network, the administrator can remotely access the server, control the power supply of the server, view the hardware status, and even perform firmware upgrades. For large-scale data center environments, remote management capabilities are crucial.

[0033] For further information, see Figure 3 The power interface 300 is connected to the CPU socket 200 through the power conversion chip 320. Generally speaking, the CPU VCORE (core voltage) requires a large current. In terms of design, we use the 12V system power provided by the power module to flow into the power conversion chip 320 through the power interface 300 to convert this part of the power and provide it to the CPU. As for the power conversion chip 320, it converts the 12V system power into the specific voltage required by the CPU, while ensuring the stability of the power supply and reducing the impact of current fluctuations on the CPU.

Through the aforementioned detailed description of a mainboard, those skilled in the art can clearly know the implementation method of the computer in this embodiment.

[0035] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0036] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
