What Is a Socket 775 Heatsink?

The socket of Intel processors is usually called "LGA775", where "LGA" represents the packaging method of the processor, and "775" represents the number of contacts. Before the emergence of LGA775, the sockets of Intel and AMD processors were called "Socketxxx", where "Socket" actually means socket, and "xxx" means the number of pins. For example, Intel's LGA775 socket is also called Socket 775 or Socket T.

LGA775

Usually put Intel
LGA (LAND GRID ARRAY) is the packaging method of the INTEL64-bit platform. The contact array package is used to replace the old Socket 478 interface, also called SocketT, usually called
The single-core Pentium 4, Pentium 4 EE, Celeron D and dual-core Pentium D, Pentium EE, Core 2 and other CPUs in the LGA775 package are used for this interface. Unlike the previous Socket 478 interface CPU, the socket of the Socket 775 interface CPU does not have traditional pins at the bottom. Instead, it has 775 contacts, that is, not pin type but contact type. The stylus contacts to transmit the signal. The 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 of Socket 478, Socket 775 has become the standard interface for Intel desktop CPUs.
In addition, this change can effectively overcome the signal interference caused by pin contact. Because the traditional CPU uses pin package design, when the processor runs at high frequency, it will cause a lot of signal noise and product interference. In order to avoid these high-frequency noise interference, Intel redesigned the SocketT processor installation interface for the new generation platform. Although the new design solves some of the original problems, it also brings some unexpected disadvantages: the contacts on the SocketT socket are easily damaged and broken, which may cause the entire motherboard to be scrapped in serious cases.
Intel is therefore accused of adopting a pin-less design for its processors, in order to avoid a large number of products being damaged due to broken pins, which will increase the production cost of the processor. After the processor uses the LGA775 pin-less package, the risk can be passed on to the motherboard manufacturer. . Intel certainly did not respond positively to these rumors, but the company said it would strengthen the strength of the SocketT socket to reduce the chance of damage.
The new-generation processor moved from Socket478 to LGA775. Why is the purpose of adding a large number of pins? Some news indicates that it is used to expand the requirements of 128bit bus and is also reserved for the use of EM64T
The LGA775 CPU has no pins, only a few metal points, a total of 775. The pins of the LGA775 processor are actually made on the motherboard. There are 775 pins with certain flexibility on the motherboard. They can withstand these metal points to reach the CPU. The purpose of work.
Generally speaking, the processor with 462 architecture is 462 pins. 478 is 478 pins. 370 is 370 pins ... In this regard, Intel and
The LGA1156 socket used by the Lynnfield / Clarkdale processor is worth considering. Although it is clear
Because the production and yield of semiconductor chips are not high in the initial stage of production, chip manufacturers usually first concentrate their conversion into those flagship products with higher performance but lower output, until the output and yield of the chip reach a certain level of maturity. Later, it will spread to mainstream markets with larger shipments. For example, Intel has released its new generation based on as early as November 2008.

We saw the new LGA1155 interface for the first time in early 2009, but knew nothing about its purpose. Some people say that it and LGA1157 are only test interfaces. The final choice was LGA1156. However, according to Japanese PCWatch columnist Hiro Moto, the LGA1155 will be used in the future 32nm process new architecture Sandy Bridge family, and it will quickly spread It will become mainstream in two years.
If so, there will be four Intel desktop processor interfaces in recent years. The main uses and development trends are as follows:
-LGA775: It has been in service for many years and has undergone many changes. It is also the current mainstream platform, but it will be phased out within two years, and will only account for about 8% in the second half of 2011.
-LGA1366: Nehalem micro-architecture is only for high-end models, such as quad-core Bloomfield and six-core Gulftown. It will not be promoted. In the past two or three years, it will always only have a 2-3% share.
LGA1156: used by mainstream and low-end models of the Nehalem family, such as quad-core Lynnfield and dual-core 32nm Clarkdale, which appeared in the second half of 2009, occupying 40-50% from the second half of 2010 to the first half of the following year, but will soon give way It will be less than 25% in the second half of 2011.
-LGA1155: It will be used for the next-generation micro-architecture 32nm Sandy Bridge, similar to the positioning of LGA1156. Launched in 2011 will account for nearly 30%, and it will rapidly increase to 65% in the second half of the year.
Sandy Bridge uses the same 32nm production process as the upcoming Westmere family, but will upgrade the new architecture again, integrating graphics cores, DDR3 memory controllers, former Northbridge modules, etc. The mainstream quad-core chips have been successfully streamed in early June.
Sandy Bridge released in 2010 finally used the LGA1155 interface [1]

There have been a lot of Mini-ITX motherboards using NVIDIA ION MCP7A ion chipset, but they are all aimed at Intel Atom processors. Although the system is lightweight, its performance is limited. AOpen is now the first to bring the ion chipset to the LGA775 platform, and it is still a mini board.
The motherboard model "nMCP7AUt-V", the chipset is a high-end MCP7A-U GeForce 9400, supports DX10.0, Hybrid SLI, GeForce Boost, PureVideo HD, PhysX and many other technologies, can be matched with the thermal design power consumption is not higher than 95W, Core 2 Duo / Quad / Extreme, Pentium, Celeron series processors up to 1333MHz, equipped with a PCI-E 2.0 x16 expansion slot, two DDR2-1066 / 800/667 SO- DIMM memory slot (maximum capacity 4GB), three SATA 3Gbps interfaces (RAID 0/1/5 / JBOD), Realtek ALC889 7.1 + 2-channel integrated sound card, Realtek RTL8211C Gigabit integrated network card.
The back interface has two PS / 2, six USB 2.0, DVI, HDMI. Unfortunately, no optical fiber and coaxial S / PDIF are provided, which is a pity for the HTPC. [6]
