They must have patched the BIOS for the 760 board themselves right? I can't believe one with stock BIOS would function beyond failsafe clocks with BD.
Patched? Asus officially supports 32nm CPUs with this Board and the latest stock public Bios. But B2 Stepping was not fully supported with the older Bios obviously, therefore it can't show the real performance. M5A97 with the very new Bios from Asus made the difference.
