Don't even have to worry about BIOS version. That CPU has been supported since day 1.Yes, it supports 6th and 7th gen chipsets. http://ee.gigabyte.com/products/page/mb/ga-b250m-d2v#kf
It works with the first BIOS version so no problems.I have a B250M-D2V motherboard, will it support the i7-7700?
Thanks for your help
