I believe that they rushed all thees i7 boards out because the market was slow. Most of the first bios did not even run 12GB. Now some report 24GB support.

ASUS pulled the support for the I/OxAPCI Interrupt Controller because it has a memory conflict on the x58. Intel notes it needs to be moved/ located on the ICH10R

Well soon the LGA-1156 will be out in many flavors. I am sure some will be fantastic OverClockers and the i7 will step back for the new socket.
