Hmm.. is that just suicide running with CPU-Z or is that stable?

I dont plan on running it stable at those frequencies im just trying to get it to go as fast as possible,
The WR for my chip ATM is 6422.48MHz here:

Using a VCore of 1.84V!
How come his or indeed anyof the LN2'ers chips explode or refuse to work anymore?

This guys is @ 1.87V!

I dont get how people can say they blow up @ those voltages and there are plenty of cases where OC'ers can get then toeven 1.87V?
