The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors), is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. A pin grid array, often abbreviated PGA, refers to the arrangement of pins on the integrated circuit packaging ZIF is an acronym for zero insertion force, a concept used in the design of IC sockets invented to avoid problems caused by applying force upon insertion and The Athlon 64 is an eighth-generation AMD64 architecture Microprocessor produced by AMD, released on The Athlon 64 X2 is the first dual-core desktop CPU manufactured by AMD. The Athlon 64 is an eighth-generation AMD64 architecture Microprocessor produced by AMD, released on The Opteron is AMD 's X86 server processor line and was the first processor to implement the AMD64 Instruction set architecture (known Sempron has been the marketing name used by AMD for several different entry level desktop CPUs using several different technologies and CPU socket Phenom (pronounced as IPA/finɒm/ as in the word phenomenon) is the AMD desktop processor line based on the K10 ( not "K10h") microarchitecture A CPU socket or CPU slot is a connector on a computer's Motherboard that accepts a CPU and forms an electrical interface with it Cyrix was a CPU manufacturer that began in 1978 in Richardson Texas as a specialist supplier of high-performance math co-processors for 286 and A CPU socket or CPU slot is a connector on a computer's Motherboard that accepts a CPU and forms an electrical interface with it It was released on May 23, 2006, as a replacement for Socket 939 & Socket 754.

Socket 939 is a CPU socket released by AMD in June 2004 to supersede the previous Socket 754 for Athlon 64 processors Socket 754 is a CPU socket originally developed by AMD to succeed its Athlon XP platform (Socket 462 also referred to as Socket A)

Technology
AM2 processors are incompatible with 939 motherboards and vice versa, and although it has 940 pins, it is incompatible with Socket 940[1]. Chipsets Socket 940 motherboards are currently available with the following chipsets AMD's own 8000-series VIA K8T890 nVidia nForce3 Pro DDR2 can transfer more data per clock cycle, but suffers from higher latencies, while drawing less power than DDR memory, which the previous Socket 939 supported. DDR SDRAM ( double data rate synchronous dynamic random access memory) is a class of memory Integrated circuit used in Computers It achieves nearly twice Socket 939 is a CPU socket released by AMD in June 2004 to supersede the previous Socket 754 for Athlon 64 processors AnandTech reported that Socket AM2 system performance was 0-7% faster than Socket 939 equivalents, with most applications about 2% faster [2][3], despite having over 30% greater memory bandwidth due to DDR2 support. AnandTech is one of the largest Online Computer hardware Journals in the English-speaking world
The first processor cores to support socket AM2 are the single-core Orleans (Athlon 64) and Manila (Sempron), and the dual-core Windsor (Athlon 64 X2 and Athlon 64 FX). The Athlon 64 is an eighth-generation AMD64 architecture Microprocessor produced by AMD, released on Sempron has been the marketing name used by AMD for several different entry level desktop CPUs using several different technologies and CPU socket The Athlon 64 X2 is the first dual-core desktop CPU manufactured by AMD. The Athlon 64 is an eighth-generation AMD64 architecture Microprocessor produced by AMD, released on Most processors on Socket AM2 include SSE3 instructions and were developed with 90 nanometer technology. SSE3, also known by its Intel code name Prescott New Instructions (PNI, is the third iteration of the SSE instruction set for the IA-32 architecture The 90 nanometer (90 nm process refers to the level of CMOS process technology that was reached in the 2002-2003 timeframe by most leading semiconductor companies Recent models feature 65 nanometer technology (to compete with Intel and their 65nm CPUs). The 65 nanometer (65 nm process is an advanced lithographic node used in volume CMOS Semiconductor fabrication.
Socket AM2 supports AMD Phenom processors but some motherboard manufacturers did not supply newer bios files required to operate a Phenom processor. Phenom (pronounced as IPA/finɒm/ as in the word phenomenon) is the AMD desktop processor line based on the K10 ( not "K10h") microarchitecture
Socket AM2 is a part of AMD's next generation of CPU sockets, along with Socket F for servers and Socket S1 for mobile computing. Socket F is a CPU socket designed by AMD for its Opteron line of CPUs, and released on August 15 2006. Socket S1 is the CPU socket type used by AMD for their Turion 64, Athlon 64 Mobile and later Sempron processors which debuted
There are also single-socket Opteron processors available for AM2. The Opteron is AMD 's X86 server processor line and was the first processor to implement the AMD64 Instruction set architecture (known [4]
While technical documentation was readily available for earlier generations of AMD processor sockets, the "AM2 Processor Functional Data Sheet" (AMD document number 31117) has not been made publicly available.
Successors
Multiple sockets have been announced which are pin-compatible with socket AM2, but which differ in terms of features.
- Socket AM2+
Socket AM2+ is an intermediate successor to socket AM2, which features split power planes, DDR2 SDRAM and HyperTransport 3. Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is currently used by several AMD Processors such as Athlon 0. Socket AM2+ chips can plug into a socket AM2 motherboard, but operates only with HyperTransport 2. 0.
- Socket AM3
AMD has announced that Socket AM3 processors will be able to run on Socket AM2 motherboards, but not vice-versa. Socket AM3, which will be used in future AMD CPU releases is a CPU socket designed by AMD for desktop processors, including AM3 processors will have a new memory controller supporting both DDR2 and DDR3 SDRAM, allowing backwards compatibility with AM2 and AM2+ motherboards. In Electronic engineering, DDR3 SDRAM or double-data-rate three Synchronous dynamic random access memory is a Random access memory Since AM2 processors lack the new memory controller, they will not work on AM3 motherboards.
