You are right Yair22, its not logicial.
From my understanding all that is required is a micro-code update to the BIOS for IvyBridge-E support. As I mentioned all of the major motheboard manufactuers have updated BIOS's that support IVB-E. I don't know Intel's reasoning not to support but, now I'm stuck with a $275 deadend motherboard.
I mean come on Intel.... take my money, I want to buy a 4930K...
