主板CPU插槽类型

主板CPU插槽类型 We know that CPU needs to work through an interface to connect to the motherboard. CPU after many years of development, the interface methods include pin type, card type, contact type, pin type and so on. At present, the interface of CPU is pin type interface, corresponding to the type of slot on the motherboard. Different types of CPU have different CPU slots, so select CPU, and you must select the motherboard with the slot type. The main board CPU slot type is different, in the number of sockets, volume and shape are changed, so they can not plug each other. AMD's Socket AM2 slot uses a new design processor slot, which has 940 pins, the processor built-in DDR2 memory controller, you can support up to DDR2 800 of memory. While AMD plans to start a unified processor slot from the AM2 slot, all of the future AMD desktop processors, including Athlon 64, Athlon 64, X2, and Sempron processors, will use this interface. Note that the AMD AM2 architecture called Rev or F, the official release time can be called AM2, and the AMD processor will claim that the official support for DDR2-533, 667 and 800 memory, while rival Intel is currently the highest memory support rate was only 667 DDR; but until the third quarter, Intel when I launched the Conroe core processor, Intel will gradually introduce DDR2 800 support. The Socket 939 slot is the interface type used by the Athlon64 processor, with 939 pins. The motherboard that supports the Socket 939 processor only requires 4 layers of PCB. Use plain DDR memory. The Socket 940 slot is the interface type used by the Athlon64 processor, with 940 pins. Socket 940 interface processor support dual channel ECC memory, support Socket 940 processor motherboard must use 6 to 9 layers of PCB, must use the DDR memory with ECC check. The Socket 754 slot is the interface type used by the Athlon64 processor, with 754 pins. The Socket 754 interface processor supports single channel memory The LGA 775 slot is the Intel 925X Express and Intel 915 Express chipset, the type of interface used to support Pentium 4 and Pentium 4 Extreme Edition processors, with a pin number of 775 pins. The Socket 478 slot is the type of interface currently used by the Pentium 4 series processors, with 478 pins. The Pentium 478 Socket 4 processor has a small footprint and very tight stitches. A large number of motherboard products using Socket 478 slots, is the most widely used slot type. Socket A interface, also known as Socket 462, is the current AMD company Athlon XP and Duron processor socket standards. Socket A interface has 462 plug-in, can support the 133MHz fsb. As with the Socket 370, the manufacturing cost is reduced and the structural design is simplified. The Socket 423 slot is the standard interface for the original Pentium 4 processor, and the shape of the Socket 423 is similar to the slots in the previous Socket classes, with the corresponding number of CPU pins being 423. Socket 423 slots are mostly based on the Intel 850 chipset motherboard, which supports 1.3GHz ~ 1. 8GHz Pentium 4 processor. However, with the popularity of DDR memory, Intel has developed a i845 chipset that supports SDRAM and DDR memory, and the CPU slot has changed to Socket 478, and the Socket 423 slot has disappeared. The Socket 370 architecture was developed by Intel to replace the SLOT architecture, which looks very much like Socket 7, and uses a zero insertion force slot, where the corresponding CPU is 370 pin. Socket 370 motherboard for the use of Intel, ZX, BX, i810 chipset products, other manufacturers have VIA, Apollo, Pro series, SIS 530 series and so on. Initially, Socket 370's CPU upgrade capability may not be so good, so Socket 370 sales are always better than the SLOT 1 interface motherboard. But in Intel launched the "copper" and "CPU" series, the Tualatin Socket 370 interface board a low-end image, gradually replaced the SLOT 1 interface. At present, there are a small number of motherboards in the market using such slots. SLOT 1 is a patent for Intel's CPU interface developed to replace Socket 7. In this way, other manufacturers can not produce SLOT 1 interface products, which makes AMD, VIA, SIS and other companies had to unite to upgrade the Socket 7 interface, but also got the Super 7 interface. Later, with the rise of the Super 7 interface, Intel will manufacture SLOT 1 motherboard authorization provides VIA, SIS, ALI and motherboard manufacturers, so these manufacturers also launched a series of motherboard with SLOT 1 interface, enrich the motherboard market. ??? SLOT 1 is Intel company for slot Pentium II Series CPU design, the Pentium II CPU and related control circuit, the two level cache are done on a piece of card, the majority of Slot using 100MHz 1 motherboard fsb. The technology architecture of SLOT 1 is relatively advanced, providing greater internal transmission bandwidth and CPU performance. Using SLOT 1 interface motherboard chipset, there are Intel BX, i810, i820 series and VIA Apollo series, ALI Aladdin, Pro II series, and SIS's 620, 630 series. This interface has been eliminated, the market has no such interface motherboard products. SLOT 2 applications are more professional, are used in high-end servers and graphics workstations system. The CPU used is also expensive, the Xeon (Zhi Qiang) series. There are many differences between Slot 2 and Slot 1. First, the Slot 2 slot is longer and the CPU itself is larger. Second, Slot 2 is able to handle higher requirements for multipurpose computing, the key to access to the high-end enterprise computing market. In the standard server design at that time, the average vendor could only use two Pentium II processors in the system at the same time, and after the Slot 2 was designed, 8 processors could be used in one server simultaneously. Moreover, the Pentium II, which uses the Slot 2 interface, has adopted the most advanced 0.25 micron manufacturing process at that time. The motherboard chipset that supports the SLOT 2 interface has 440GX and 450NX. The SLOT A interface is similar to Intel's SLOT 1 interface for use by AMD's K7 Athlon. In terms of technology and performance, the SLOT A motherboard is fully compatible with the original peripherals expansion card devices. It does not use Intel's P6 GTL+ bus protocol, but rather Digital's Alpha bus protocol, EV6. The EV6 architecture is a more advanced architecture that uses multithreaded point-to-point topology to support the 200MHz bus frequency. Support SLOT A interface structure of the motherboard chipset, there are two main types, one is the AMD AMD 750 chipset, and the other is the VIA Apollo KX133 chipset. Such interfaces have been fully replaced by the Socket A interface. Socket 7:Socket means slot in English, and Socket 7 is also called Super 7. The first is the Intel MMX series CPU Pentium slot design, then Intel abandon Socket 7 interface to SLOT 1 interface, AMD, VIA, ALI, SIS and other manufacturers still use this interface, until the development of Socket A interface. The slot is characterized by a 321 socket and the system uses 66MHz bus. Super 7 increase of 100MHz and AGP FSB interface type support. Super 7 uses chipsets such as VIA's MVP3 and MVP4 series, SIS's 530/540 series, and ALI's Aladdin V family. The products corresponding to the Super 7 interface CPU are AMD, K6-2, K6- III, Cyrix, M2, and some other vendors' products. Such interfaces are now obsolete and only some of the older products can be seen.
