Title: Z170 feature support for Kaby Lake?
Post by: HAPPYCAT on January 06, 2017, 04:34:57 pm

I have a Z170XP-SLI and there is a BIOS update F20 that adds support for Kaby Lake processors.

Reading the Anandtech review for the 7700K http://www.anandtech.com/show/10968/the-intel-core-i7-7700k-91w-review-the-new-stock-performance-champion/11 (http://www.anandtech.com/show/10968/the-intel-core-i7-7700k-91w-review-the-new-stock-performance-champion/11) they state:

There’s also a new feature worth mentioning before we get into the meat: AVX Offset. We go into this more in our bigger overclocking piece, but the crux is that AVX instructions are power hungry and hurt stability when overclocked. The new Kaby Lake processors come with BIOS options to implement an offset for these instructions in the form of a negative multiplier. As a result, a user can stick on a high main overclock with a reduced AVX frequency for when the odd instruction comes along that would have previously caused the system to crash.

My question is, does the new BIOS update for the Z170 boards (including my Z170XP-SLI) contain an option now to control the AVX instruction offest?

For now I would stay away from F20. There is a lot people having problems with. If you can find out what you want to know about the bios. Then it is up to you if you want to use it. If you do run into problems you can go back to a early version. There is a few threads on how to do it.
