Yeah I am not sure what is going on with these CPU's I have tried. I see boostedevo above was hitting 5ghz with 1.5vcore, mine would not even boot unless I was close to 1.7vcore which was just to much load for SS Phase.

Sometime wrong with the ES CPU's or board, I dont know, maybe its just me.

I did get a Dominator GT 2000mhz RAM kit were I could really tighten up the RAM timings and thats what I used on these last runs, but getting to 2000mhz was not easy, where as on my other Dominator 1600mhz kits I could get to 2000mhz easy but could not get the RAM very tight.

So in the end of all this I am scratching my head going crappy ES CPU's or something wrong with the board, I don't know. The more I see what others are doing I am begging to think something is up with the MB as 2 ES CPU's now are doing pretty much the same thing.
