You will need to update to the latest BIOS version, after that, just swap in the new CPU and you are done  I ran my 7600k on my Z170 Pro4s on the latest BIOS without any issues at all so you shouldn't have any problems. -------------

" rel="nofollow - Clear CMOS and try again. Make sure you leave the system powered for 10mins or so before powering off. If using the clear CMOS jumper does not fix it then try this method: http://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal -------------

I am sorry to hear that, bad flashes can happen sometimes  We recommend using instant flash from inside the UEFI, it is less likely to break things than other methods. Good luck and let us know how it goes. -------------
