Im a bit disappointed that its not released for the Extreme assembly so I can try it out. Seems this board has been left out in the cold on a lot of updates. I asked support if the two were interchangeable and if it was just an oversight on not updating the Extreme Assemblies web page as I wanted to run to try the Kaby Lake 7700K (just because I cant at this point LOL) and listed in detail the BIOS and drivers that were currently installed. Of course All I get is the standard generic responses. First was, Im sorry blah blah blah, I will forward this to next level support. Second response told me to update to BIOS 2202 and the latest drivers listed on the download page which I had done long ago, as in the same day I started up the system from a new build, Actually the chipset driver has been updated from intels downloads, the wifi from broadcom as they dont even have one listed on the Extreme assy page and of course as with any the graphics drivers. I have to say its almost as if its just a machine response or C&P response. Im not going to venture into installing Kaby lake on this board as its too much of a PITA. Full cover block means I have to remove the MOBO to make the change which means draining the loop and disassembly of the PETG tubing. Too much work for a maybe, especially if I have to do it twice to put the 6700K back. Im not going to bother with the Z270 as Im holding out for the X299 and skylake X later in the year. Some sources say second half but they have already sent out engineering samples.

I was going to update my Extreme MB bios, but it won`t update it. It says it is already the latest bios, (2202) but it`s not.
I always update my bios using EZ Flash 3. For some reason it won`t update by this method.
