many north-south bridges can't determine the memory and slot. For example, some 865 motherboards can support 478, some can support 775 cpu, some can support ddr memory, and some can support ddr2 memory.
the key is to look at the support list of the motherboard, which is explained in detail in the motherboard manual and is generally known by the sales staff. Moreover, this problem will take a long time to accumulate knowledge.
interface type
we know that the CPU needs to be connected to the motherboard through an interface to work. After so many years' development, the interface modes adopted by CPU are pin type, card type, contact type and pin type. At present, the interface of CPU is pin interface, and there are corresponding slot types corresponding to the motherboard. Different types of CPU interfaces vary in the number, volume and shape of jacks, so they cannot be plugged into each other.
Socket 775
Socket 775, also known as Socket T, is the interface corresponding to the CPU packaged by Intel LGA775. At present, there are Pentium 4, Pentium 4 EE, Celeron D and other CPUs packaged by LGA775. Different from the previous Socket 478 interface CPU, the bottom of Socket 775 interface CPU has no traditional pins, but 775 contacts instead, that is, it is not pin type but contact type, and transmits signals by contacting with 775 contact pins in the corresponding Socket 775 slot. Socket 775 interface can not only effectively improve the signal strength and frequency of the processor, but also improve the yield of the processor and reduce the production cost. With the gradual fading out of Socket 478, Socket 775 will become the standard interface for all Intel desktop CPUs in the future.
Socket 754
Socket 754 is the CPU interface when AMD64-bit desktop platform was first released in September 23. At present, there are low-end Athlon 64 and high-end Sempron, which have 754 CPU pins. With the popularity of Socket 939, Socket 754 will eventually fade out.
Socket 939
Socket 939 is a 64-bit desktop interface standard introduced by AMD in June 24. At present, there are high-end Athlon 64 and Athlon 64 FX with 939 CPU pins. Socket 939 processor and Socket 94 slot can't be mixed, but Socket 939 still uses the same CPU fan system mode, so the fans used for Socket 94 and Socket 754 can also be used for Socket 939 processor.
Socket 94
Socket 94 is the earliest published AMD64-bit interface standard, with 94 CPU pins. Currently, Opteron used by servers/workstations and Athlon 64 FX are used as the interface. With the new Athlon 64 FX switch to Socket 939 interface, Socket 94 will become Opteron's special interface.
Socket 63
Socket 63 is used professionally, and it is applied to Intel's high-end server/workstation platform. The CPU using this interface is Xeon MP and early Xeon, with 63 CPU pins. The CPU of Socket 63 interface can be compatible with Socket 64 slot.
Socket 64
Similar to Socket 63, Socket 64 is still a high-end server/workstation platform applied to Intel. The CPU using this interface is Xeon with 533MHz and 8MHz FSB. The CPU of Socket 64 interface is not compatible with Socket 63 slot.
Socket 478
Socket 478 interface is the interface type adopted by Pentium 4 series processors at present, with 478 pins. The Pentium 4 processor of Socket 478 has a small area and its pins are arranged very closely. Intel's Pentium 4 series and P4 Celeron series all use this interface.
Socket A
Socket A interface, also called Socket 462, is the socket interface of Athlon XP and Duron processors of AMD. Socket A interface has 462 slots and can support 133MHz external frequency.
Socket 423
Socket 423 is the standard interface of the original Pentium 4 processor. The shape of Socket 423 is similar to that of the previous Sockets, and the corresponding number of CPU pins is 423. Socket 423 slots are mostly based on Intel 85 chipset motherboards, which support Pentium 4 processors at 1.3 GHz to 1.8 GHz. However, with the popularity of DDR memory, Intel developed the i845 chipset supporting SDRAM and DDR memory, and the CPU slot was changed to Socket 478, so the Socket 423 interface disappeared.
Socket 37
Socket 37 architecture is developed by Intel to replace SLOT architecture, which is very similar to Socket 7 in appearance, and it also uses a zero insertion force slot, and the corresponding CPU is 37 pins. Intel's famous "Copper Mine" and "tualatin" series CPU adopt this interface.
SLOT 1
SLOT 1 is a CPU interface developed and patented by Intel corporation to replace Socket 7. In this way, other manufacturers can't produce products with SLOT 1 interface. The CPU of SLOT1 interface is no longer the familiar square shape, but has become a flat cuboid, and the interface has also become a golden finger, no longer in the form of a pin.
SLOT 1 is a slot designed by Intel Corporation for Pentium II series CPU. It integrates Pentium II CPU, its related control circuits and secondary cache on a daughter card, and most Slot 1 motherboards use 1MHz external frequency. SLOT 1 has an advanced technical structure, which can provide greater internal transmission bandwidth and CPU performance. This kind of interface has been eliminated, and there is no such interface product on the market.
SLOT 2
SLOT 2 is used professionally and is used in high-end servers and graphics workstation systems. The CPU used is also an expensive Xeon series. There are many differences between Slot 2 and Slot 1. First of all, the Slot 2 slot is longer and the CPU itself is larger. Secondly, Slot 2 is competent for multi-purpose computing with higher requirements, which is the key to enter the high-end enterprise computing market. In the standard server design at that time, the general manufacturer could only use two Pentium II processors in the system at the same time. With the design of Slot 2, eight processors can be used in one server at the same time. Moreover, Pentium ⅱ CPU with Slot 2 interface adopted the most advanced .25 micron manufacturing technology at that time. Motherboard chipsets supporting SLOT 2 interface include 44GX and 45NX.
SLOT A
SLOT A interface is similar to Intel's SLOT 1 interface and is used by AMD's K7 Athlon. In terms of technology and performance, SLOT A motherboard is fully compatible with all kinds of original peripheral expansion cards. It does not use Intel's P6 GTL+ bus protocol, but Digital's Alpha bus protocol EV6. EV6 architecture is an advanced architecture, which adopts multi-threaded point-to-point topology and supports 2MHz bus frequency.
