Being based on the nForce4 Ultra chipset, the KN1 Extreme supports all current AMD Socket 939 CPUs. The CPU support list includes listing for the Athlon 64 X2 dual core CPUs. One thing about the AMD platform is support for CPUs on the same interface. Intel dual-core CPUs require a separate chipset (945 or 955) from the previous ones (925X and 925XE or 915). The nForce4 Ultra chipset supports HyperTransport speeds of up to 2GHz.
