Socket 940is a 940-pin socket for 64-bitAMDOpteronserver processors and AMDAthlon 64 FXconsumer processors. It was one of the first sockets designed for AMD'sAMD64range of 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'sOpteronand the older AMDAthlon 64 FX(FX-51) use Socket 940.
Technical specifications
[edit]Microprocessorsdesigned 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 onlyregistered memory.[1]
While the more recent 940-pinsocket AM2is visually similar to this one, the two are electrically incompatible due to the integratedmemory controller.Socket 940 CPUs integrate aDDRcontroller, whereas AM2 models use aDDR2controller.[2]
