It seems my Z170A motherboard is the only one not getting an update? :P

I guess these sort of updates might be useful for people who somehow lose their CPU after the warranty period is over, or if they had the cheapest non-K i5 and wanted to switch to an i7. Otherwise a switch from Sky to Kaby is no upgrade. Someone building an entirely new machine with Kaby would obviously be better off with the 200 series mobo.

nvm.

Pretty easy to insert microcode for kaby lake into the bios, if its necessary

The new BIOS for the Z170A M7 seems to have some problems with RAM timings even when using exactly the same settings as with previous BIOS. tRAS doesn't want to go as low as it could on BIOS v1.C. Used to have tRAS set to 34 (timings set were 2800MHz 1-15-15-15-34-278), now tRAS doesn't go lower than 40 (2800MHz 1-15-15-15-40-278). Doesn't bother me but a bit odd anyway.

No upgrade? If the recent leak about the 7700k is to be believed, it could have potentially up to 12-15% single threaded and even higher multi threaded performance improvement over Skylake 6700k. I'd say that is an upgrade, not to mention that Kaby should be way better for encode/decode since it will feature some new instruction sets as well as a higher base clock at 4.2ghz.. could be the next 'sandy bridge' type overclocker. Bottom line is, I wouldn't write off Kaby so quickly
