ICH10R southbridge, X58 board. DFI X58-T3eH6, Core i7 920, 12GB RAM. Again, I flashed countless times without any issue, using exactly the same methods, cable, port, card reader, everything. That was the only thing that made me give it another shot; if it hadn't happened thus far and was truly a system-related thing, it wasn't going to happen now. It did. Consistency does not apply, unfortunately.
