It could be that you got lucky and got chip which can boot into windows at that speed.
It doesnt mean its stable. Did you run prime95 or intelburntest ? If not try these programs and see if it will find an error or your pc will crash.
Also,I noticed that sometimes when cpu is overclocked too far it can actually be slower then it should be,even slower then stock speed.
Which speeds did you try ? Ony stock and that high overclock ? Its completely posible to get same perfomance as stock speed if cpu is unstable.
Try normal overclock and see what speeds you get. For example start with 3 ghz
