"Both of the socket 1156 Processoers reach clock speeds above 4.2 GHz with the 870 reaching almost 4.5GHz with some benchmark stability. That just about floored me, since this literally is the fastest air cooled CPU I have ever tested! Even water cooled my best i7 920 is a 4.3 GHz chip. The Kingsberg board proved to be easy to overclock and delivered excellent performance. The one thing I had hoped was fixed was the extreme temperatures delivered when you throw the current to the processor. Each chip took some voltage reach the maximum clock speeds and responded with temperatures that the CO stepping i7 920s delivered."
