Although both have 940 CPU pins, Socket AM2 is different from the original Socket 940 in pin definition and pin arrangement, and is not compatible with each other. Low end socket AM2 interface Sempron , Mid end Athlon 64 , high-end Athlon 64 X2 And the top Athlon 64 FX and other full range AMD desktop CPUs, supporting 200MHz fsb And 1000MHz HyperTransport Bus frequency, supporting dual channels DDR2 memory Among them, Athlon 64 X2 and Athlon 64 FX support up to DDR2 800, Sempron and Athlon 64 support up to DDR2 667. According to AMD's plan, Socket AM2 interface will gradually replace the original Socket 754 Interfaces and Socket 939 Interface to realize desktop platform CPU interface Unification of. Its predecessor is the Slot A interface, which is the so-called "long term integration must be separated, long term separation must be combined"
