Motherboard using Intel's Z170 chipset have been out since before the Kaby lake line of CPUs (7th generation core processors a.k.a. 7000 series) were out. In several online stores you still see them listed as supporting "6th generation" Intel core processors (6000 series). I have noticed that several forums claim that you can run Kaby lake CPUs on Z170; and others say you need a BIOS upgrade. (The socket is physically the same.)
So, which is it, among the following options:
- Can't use Kaby lake's with Z170 boards at all
- Always need a BIOS upgrade, which manufacturers don't pre-apply
- Kaby lakes just run on Z170s out of the box
- Depends on the manufacturer and/or the motherboard model (please elaborate if you can)
