Checked the core today, sorry to say that it dosnt have a g-72 on it.
The code on my ultra says (N1-7644.00 050 9b1)
I still think it may be a disguised 7 series chip by the way these things overclock. Also the way that it throttled the core up in 3 steps (450-495-546) when we auto overclocked. We need someone that knows there way around a 7 series bios to look it over and compare it to the desktop 7800 series bios. Im going to start a thread over at
www.extremsystems.org to see if these guys want to jump into it with us.
Later,
Josh
