A 19 year old Finnish techie, who is called Stilt, has managed to overclock his P4 560, 3.60GHz processor to more than 6009 MHz with the help of liquid nitrogen cooling. I don't see any comments about stability (that's anyone's guess) but we all sure have to admit that that is one big overclock that's been done there. Hats off to Stilt. R.E.S.P.E.C.T.
