Gigabyte has released the Bios revision F4 for the new 7DXR. As usual, nobody can tell the difference, anyway it works without problem. It's for sure not a performance tweaking bios, such as the latest A7M266 bios, because the benchmarks are all the same. The A7M266 got 5 additional commands for memory settings, which gave a nice little boost, when set to more agressive timings. The 8K7A and the DA-7DXR bios' look both quite poor in the bios memory department.
