Yes it did indeed but not the way it's described by Asus. I couldn't get it to flash and tried different USB drives, re-formatted the drives, tried holding the rog connect button for 30 seconds but the led close to the bios chip went on solid (no blinking) and it wasn't reading from the usb drive at all.

Finally after i renamed the bios M5G.CAP instead of M5G.ROM it flashed without trouble! Now i'm back at bios 0903 but i might give 0078 a go, in hindsight that was the best bios i've used.

The reason bios 1101 requires more Vcore is down to LLC working different i think. With bios 1101 having LLC set to high makes Vcore droop almost .025V! Ultra high seems the better choice there. Actually the same goes for bios 0903 i found. With bios 0078 setting LLC to high was good enough to get very little Vdroop.
