Socket 940 is a 940-pin socket for 64-bit AMD server 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 only the acceptance of registered memory.[1]
There is a new 940-pin socket called AM2. Despite having the same number of pins, Socket 940 and AM2 are not pin-compatible. This means a Socket 940 processor will not fit in an AM2 socket and vice versa. This is because all 64-bit AMD processors integrate the memory controller onto the CPU die rather than have a discrete chip on the motherboard.[2]
