Can anyone tell me what has changed in BIOS F21 for the z170xp-sli board.
The description only says, Quote: "V core Voltage adjust", not even a proper sentence.
I read many bad things about the F20 bioses, and am surmising that the F21 may possibly fix an issue CAUSED BY the F20....
Or does this 'voltage adjust' apply to the board in general. I am running F6, should I update?
Can someone tell me exactly what the changes in F21, are besides Kaby Lake support...
Thank you

Well I bit the bullet and updated from F6 to F21 on my Z170XP-SLI.
The BIOS has a new color Scheme, (I think looks ugly), they also have improved custom fan settings.
I now have an option to use Intel Speed Shift, which I believe is an improved version of Intel Speed Step. I have yet to play around with that however.
In terms of Voltages, just to start out, I set the auto OC option in the BIOS to 4.3Ghz, left all settings on auto, using HWMonitor the highest voltage spike I get is 1.176, and when stressing 100% load under prime95 HWMonitor shows a constant voltage of 1.140-1.52V.
With Bios F6, running the same scenarios, I would get max voltage of 1.212(Or slightly higher, can't remember exactly)
So, Seems like the board definitely now uses less voltage with F21, at least when overclocking using the built in auto settings.
I haven't yet tried any manual overclocking.
I have not experienced any bugs like those reported with the F20 bios.
So far, I would say the update is worth it.

Greetings,
This is helpful feedback. Wasn't a lot of real world information out there regarding F21.
Many got burned on F20, stability issues, high temps, and OC headaches. Gigabyte was obviously paying attention and started putting out lettered beta variants to resolve problems prior to F21. Most people who flashed to F20 went back to an earlier rev. Hopefully your post will help others finding themselves in a similar situation.
