Socket 940 is a 940-pin socket for 64-bit AMD Opteron server processors and AMD Athlon 64 FX consumer processors. This socket is entirely square in shape and pins are arranged in a grid with the exception of four key pins used to align the processor and the corners. AMD's Opteron and the older AMD Athlon 64 FX (FX-51) use Socket 940.

Technical specifications

Microprocessors designed for this socket were intended to be used in a server platform, and as such provide additional features to provide additional robustness. One such feature is the acceptance of only registered memory. [1]

While the more recent 940-pin socket AM2 is visually similar to this one, the two are electrically incompatible due to the integrated memory controller. Socket 940 CPUs integrate a DDR controller, whereas AM2 models use a DDR2 controller. [2]

HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a technology for interconnection of computer processors. It is a bidirectional serial/parallel high-bandwidth, low-latency point-to-point link that was introduced on April 2, 2001. The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology.

Opteron Server and workstation processor line by Advanced Micro Devices

Opteron is AMD's x86 former server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture. It was released on April 22, 2003, with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture were announced on September 10, 2007, featuring a new quad-core configuration. The most-recently released Opteron CPUs are the Piledriver-based Opteron 4300 and 6300 series processors, codenamed "Seoul" and "Abu Dhabi" respectively.

Athlon 64 Microprocessor by AMD

The Athlon 64 is an ninth-generation, AMD64-architecture microprocessor produced by Advanced Micro Devices (AMD), released on September 23, 2003. It is the third processor to bear the name Athlon, and the immediate successor to the Athlon XP. The second processor to implement the AMD64 architecture and the first 64-bit processor targeted at the average consumer, it was AMD's primary consumer microprocessor, and primarily competed with Intel's Pentium 4, especially the Prescott and Cedar Mill core revisions. It is AMD's first K8, eighth-generation processor core for desktop and mobile computers. Despite being natively 64-bit, the AMD64 architecture is backward-compatible with 32-bit x86 instructions. Athlon 64s have been produced for Socket 754, Socket 939, Socket 940, and Socket AM2. The line was succeeded by the dual-core Athlon 64 X2 and Athlon X2 lines.

Land grid array Type of surface-mount packaging for integrated circuits

The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket rather than the integrated circuit. An LGA can be electrically connected to a printed circuit board (PCB) either by the use of a socket or by soldering directly to the board.

Socket 939 CPU socket for old AMD CPUs

Socket 939 is a CPU socket released by AMD in June 2004 to supersede the previous Socket 754 for Athlon 64 processors. Socket 939 was succeeded by Socket AM2 in May 2006. It is the second socket designed for AMD's AMD64 range of processors.

Socket 754 CPU socket for old AMD CPUs

Socket 754 is a CPU socket originally developed by AMD to supersede its Athlon XP platform. Socket 754 was the first socket developed by AMD to support their new consumer version of the 64 bit microprocessor family known as AMD64.

The AMD K8 Hammer, also code-named SledgeHammer, is a computer processor microarchitecture designed by AMD as the successor to the AMD K7 Athlon microarchitecture. The K8 was the first implementation of the AMD64 64-bit extension to the x86 instruction set architecture.

Socket AM2 CPU socket for old AMD CPUs

The Socket AM2, renamed from Socket M2, is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939.

The AMD Family 10h, or K10, is a microprocessor microarchitecture by AMD based on the K8 microarchitecture. Though there were once reports that the K10 had been canceled, the first third-generation Opteron products for servers were launched on September 10, 2007, with the Phenom processors for desktops following and launching on November 11, 2007 as the immediate successors to the K8 series of processors.

Socket F CPU socket for AMD server CPUs

Socket F is a CPU socket designed by AMD for its Opteron line of CPUs released on August 15, 2006. In 2010 Socket F was replaced by Socket C32 for entry-level servers and Socket G34 for high-end servers.

Socket AM3 CPU socket for AMD CPUs

Socket AM3 is a CPU socket for AMD processors. AM3 was launched on February 9, 2009 as the successor to Socket AM2+, alongside the initial grouping of Phenom II processors designed for it. The sole principal change from AM2+ to AM3 is support for DDR3 SDRAM. The fastest CPU for socket AM3 is the Phenom II X6 1100T.

Socket AM2+ CPU socket for old AMD CPUs

Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is used by several AMD processors such as Athlon 64 X2. Socket AM2+ is a mid-migration from Socket AM2 to Socket AM3 and both AM2+ and AM2 socket CPUs and motherboards have the potential to operate together. Actual interoperability depends upon other factors, especially the availability of compatible BIOS software, and some PC retailers, such as Dell, have not provided compatible BIOS versions that allow use of socket AM2+ CPUs on their products utilizing socket AM2 motherboards, such as the Inspiron 531.

The AMD Bulldozer Family 15h is a microprocessor microarchitecture for the FX and Opteron line of processors, developed by AMD for the desktop and server markets. Bulldozer is the codename for this family of microarchitectures. It was released on October 12, 2011, as the successor to the K10 microarchitecture.

Athlon II

Athlon II is a family of AMD multi-core 45 nm central processing units, which is aimed at the budget to mid-range market and is a complementary product lineup to the Phenom II.

AMD Piledriver Family 15h is a microarchitecture developed by AMD as the second-generation successor to Bulldozer. It targets desktop, mobile and server markets. It is used for the AMD Accelerated Processing Unit, AMD FX, and the Opteron line of processors.

AMD Athlon X4 is a series of budget AMD microprocessors for personal computers. These processors are distinct from A-Series APUs of the same era due to the lack of iGPUs.
