Processor socket developed in accordance with the development of the processor itself. Starting from the first generation to the last generation, the change of the processor, especially the physical changes greatly affect the development of the processor socket.
Particularly the development of next-generation processors or Intel x86 architecture processors starting at 8086/80186 as an early generation processors. Until now, the development of next-generation Core processors have reached i. The development of the processor socket can be seen from the shape and number of feet from the pin or the processor itself. Early generation processors, sockets used are manifold DIP (Dual iLine Package), while now it uses socket LGA (lang Grid Array).
Processor socket is a place holder on the motherboard. The rectangular-shaped holder with small holes where the legs tertancapnya (pin-pin) processors arranged into a 2-dimensional matrix. Arrangement, location, and distance between holes exactly the same with the arrangement, location, and spacing between the pins on the processor.
The term socket (its full name is the CPU socket or socket processor) has been widely used in the computer world to describe the connector linking the motherboard with the processor, especially for the type of desktop computers and servers. The processor in question here, especially Intel x86 architecture processors.
Found a lot of sockets on the motherboard architecture produced using PGA (Pin Grid Array). As mentioned above, the socket is a lot of holes where tertancapnya (tuck) the pins or legs processor located on the underside surface of the processor.
B. Types of intel processor socket
1. Socket 370
As was mentioned earlier that the socket has 370 pin holes as many as 370 pieces. Socket 370 processors are produced to replace the old seat, which is slot 1. This socket first used by some variant of the Celeron desktop processor code-named Mendocino. Mendocino Celeron processor holder is often referred to as a complete Socket 370 PPGA (Plastic Pin Grid Array) Package.
In the next development, the socket 370 is also used by some variant of Pentium 3 desktop processor codenamed Coppermine and Tualatin. Holder in both the processor type, often referred to by the full name of the socket 370 pin FC-PGA (Flip-Chip Pin Grid Array) Package. Socket 370, but used for Intel processors, may also be used for processor Via-Cyrix Cyrix III which later changed its name to the VIA C3.
370 slot found in many mini-ITX motherboard. In fact rarely found types of motherboards for the Pentium III processor installed two kinds of seat time (dual) in the motherboard, the socket 370 and slot 1. However, the second holder can not be used together at the same time. If one is used, then the other does not work.
Should be observed that the heat sink (CPU cooler) used for Socket 370 processors, the weight should not exceed 180 grams. When the weight of the CPU cooler exceeds 180 grams, can result in damage.
Socket 370 is then abandoned by the Intel, as successor to use socket 423, 478 and 775 are used for the Pentium 4, which is subsequently used for socket 775 Intel Core 2 processors.
Socket 370 works on voltage range of 1.05 volts to 2.1 volts with 66 MHz FSB, 100 MHz and 133 MHz.
2. Socket 478
This has a socket 478 and socket 478 pin connector is quite long lived. It replaces the socket 423 socket which is very short lived and prepared to compete with socket A AMD platform. This socket supports FSB 400, 533 to 800 MHz (Depending on chipset support). This socket is also no longer uses RDRAM, DDR moment but it is cheaper than RDRAM. This socket supports Intel Pentium 4 generation Willamette, Northwood, early generations of Pentium 4 Prescott and Celeron. Chipset is quite famous in this socket is Intel i875P (Canterwood) and i865PE (Springdale).
3. Socket 775
The socket 775 is the successor of the socket 478. The socket socket is often referred to as 'T' is no longer using the pin due to various Land Grid Array (LGA). This type of socket LGA advantage is to reduce the risk of broken or bent pin when installing the processor. How to setup a processor in the LGA socket type is also slightly different. This socket supports Intel Pentium 4 generation Prescott, Cedar Mill, Celeron and also supports the next-generation Core microarchitecture processors like Core2 Duo, Core2 Quad like Conroe, Kentsfield, Yorkfield, Wolfdale, Allendale wah all Core2-based codename called.
The lifetime of the socket is quite long, even up to this writing is still scattered LGA775 platform. however this socket also had left 'hurt' for users chipset i955X and i975x (before revision) because it does not support core2 generation. This socket supports FSB (Front Side Bus) up to 1600 MHz QPB and a chipset that supports FSB 1600 Mhz is the intel X48. Popular yaang Chipset LGA775 socket include i975x, P965, P35, X38, X48, P45, and nForce 6xx and 7xx, much ya? Hehehehe ... Many long enough for her age and has passed various generations of processors, namely Pentium 4, Pentium D , Core2 Duo, Core2 Quad, Pentium Dual-Core and Celeron.
4. 1366 socket
Appropriate strategies intel tick-tock, tick means that when the fabrication shrink from 65nm to 45nm (Yorkfield, Wolfdale), while the mean change in microarchitecture tock. Well in the 'Tock' intel is launching a new architecture named 'Nehalem'. Nehalem has Integrated Memory Controller (IMC) and the use of new replacement bus FSB called Quick Path Interconnect (QPI), this technology is similar to AMD K8 Hypertransportnya.
Ah ... Stands intro! Okay this is a socket LGA 1366 socket for the high-end and enthusiast. Supported processor is the Core i7 (Bloomfield) Quad Core and Core i7 has just rolled 9xx (Gulftown) Six cores. This socket supports the use of Triple-Channel DDR3 memory. Famous in the LGA1366 chipset is only one, Intel X58, in addition to this there is not it? Nvidia also usually make for intel chipset for Nehalem but can not license.
C. Types of AMD processor socket
1. A socket
Socket AM2 Socket M2 comes from the name. Use M2 socket name can lead to confusion with the name of the production Cyrix processor, the Cyrix MII. Therefore, to avoid confusion with the name of the M2 socket is replaced with a new name Socket AM2. Is a socket AM2 socket designed by AMD for desktop processors place holder AMD's own production. Socket AM2 socket was launched to replace the old (predecessor), the socket 939 and socket 754.
Socket AM2 released to the market on May 23, 2006. Based processors are not compatible with socket AM2 motherboards using socket 940 and socket type 939 (contact hole PGA with 940), although all three have the pin / hole the same contact, the pin 940. It was reported that the Socket AM2 showed 0-7% faster performance than the socket 939 equivalent.
AMD processors compatible with socket AM2, among others:
§ single-core Processor: AMD Athlon 64 (Orleans), AMD Sempron (Manila), Opteron (Santa Ana)
§ Dual Core Processor: AMD Athlon 64 X2 Windsor and Windsor AMD Athlon 64 FX.
Processors based on socket AM2 mostly manufactured with 90 nm manufacturing technology or feature 65 nanometer and SSE3 instructions. Compatible paired with DDR2-SDRAM memory types. It can even be said to constitute the first AMD socket which lends support to the use of DDR2 SDRAM.
A socket is called by the name of artificial socket is a socket 462 AMD processors commonly used for named core AMD Athlon Thunderbird, AMD Athlon XP / MP called core Palomino, Thoroughbred, Barton, and Thorton, named core AMD Duron Spitfire, Morgan, and Applebred, and AMD Sempron cores Thorougbred name. A socket manufactured to replace its predecessor, the slot A. Since socket A is produced, all AMD processors have a 462 pin SPGA designed to be compatible with the socket.
A socket was introduced by AMD in June 2000.
The socket specification include:
o Have a pin hole 462, with 37 layout × 37 SPGA (Staggered Pin-Grid Array). Nine pin them closed, leaving 453 unused pin.
o Designed for processors with Chip form factors Ceramic Pin Grid Array (CPGA) and Organic Pin Grid Array (OPGA)
o Type socket is a zero insertion force pin grid array (PGA ZIF)
o Supports system bus DDR (Double Data Rate)-based DEC Alpha EV6 bus: 100 MHz (FSB200), 133 MHz (FSB266), 166 MHz (FSB333) and 200 MHz (FSB400)
Working on the voltage range of 1.0 volts to 2:05 Volt. AMD explained that should the mass tool (component) heat sink (cooler, heatsink and fan) not exceeding 300 grams, because if the damage exceeds the size of the processor, especially if it is not handled perfectly. Finally, socket A production gradually began to be stopped (discontinued) since switched to using the AMD socket 754, socket 939 and AM2, although some vendors are known to still provide motherboard and the processor.
2. Socket 754
Socket 754 socket is one that was developed by AMD, is the first socket that can support 64-bit processor made by AMD itself. First introduced in 2003. Originally used for desktop Athlon 64 processor cores ClawHammer name and Newcastle. Eventually be used also for the Athlon 64 Venice and low end desktop processor AMD Sempron (Paris core name and Palermo), as well as mobile Athlon 64 processor and the mobile Sempron. Socket 754 has a hole 754 contacts, used to cradle designed processor has a 754 pin type OPGA (Organic Pin Grid Array). This socket provides support voltage in the range of 0.8 volts to 1.55 volts. Socket 754 supports 64-bit memory interface uses a single channel, 800 MHz HyperTransport bus Bi-Directional, and have effective data bandwidth of 9.6 GB per second.
3. Socket 939
939 socket is a socket that is designed and manufactured by AMD. Was first released in June 2004. A second socket designed by AMD to support 64-bit processors. This socket socket replacing the predecessor, the 754 socket. Socket 939 support voltage 0.8 Volt to 1.55 Volt, 1000 MHz HyperTransport bus, which has a contact hole 939 is designed for 939 pin processor OPGA, both single-core processor and dual core. Processor Athlon 64 X2 processor 4800 + is a high clock speed using socket 939 package. Examples of processors that use socket 939, among others:
o Athlon 64 (core name ClawHammer, Newcastle, Winchester, Venis, Manchester, San-Diego, Toledo),
o Athlon 64 FX (name core ClawHammer, San Diego),
o Athlon 64 X2 (core name Manchester, Toledo),
o Sempron (Palermo core name)
o Opteron (core name Venus, Denmark).
Socket 939 supports the use of 128-bit DDR SDRAM memory Dual channel with a bandwidth of 6.4 GB per second, supports the instruction sets 3DNow!, SSE, SSE2, and SSE3. Processors that use socket generally have L1 Cache 128 KB (64 KB for data cache, 64 KB of instruction cache), and L2 Cache 512 KB or 1024 KB
4. Socket 940
Socket 940 has a contact hole 940, the processor 940 is designed for the type of pin PGA, voltage support 0.8 Volt to 1.55 Volt, as well as 800 MHz/1000MHz HyperTransport bus, compatible with DDR SDRAM. This socket is used for 64-bit processors. Examples of processors that use socket 940, among others:
o core Athlon 64 FX name Sledgehammer
Opteron (Sledgehammer core name, Troy, Athens, Italy, and Egypt)
Socket 940 processor socket is actually meant for servers. Therefore, it is widely used for socket Opteron server processor, both are configured dual processor, four processors, or eight processors.
Not compatible with socket 940 processor is designed for socket AM2, or vice versa, although both have a pin number or pin holes are the same (as much as 940 pin / pin holes). Socket 940 is designed for the use of DDR SDRAM memory, is being designed for socket AM2 DDR2 SDRAM memory usage.
On the other side. socket 939 can not be mounted on a motherboard designed for socket 940, socket although both are equally designed using DDR SDRAM memory. Socket 939 requires unbuffered memory, while the 940 requires registered memory sockets. Motherboard socket 940 is designed to use available on the market with a partner chipsets:
o AMD's own 8000-series
o VIA K8T890
o nVidia nForce3 Pro
o nVidia nForce4 Professional
