I see you running RAM PL8 try to increase MCH core around 1.38-1.4 may be help. If cannot pass you need to run PL9 test stability, and also try set this

CPU Clock Drive...........................: 800mv
PCI Express Clock Drive...................: 900mv
CPU Clock Skew (ps).......................: Auto
MCH Clock Skew (ps).......................: [150PS] <----This can help stablity while using High FSB

What strap are you using? Try "D" it can be relaxing your ram timimg more than "B"

Anyway If it's still can't boot let post your Bios setting
