Gigabyte Z170X-Gaming-7 - overclocking options grayed out?

[CrashOveride]

Hey there,

I bought this board used (a bit old at this point, I know) and it's go the latest BIOS version F22m - but for some reason most of the overclocking bios options are grayed out - along with 4g decoding (which I think may be required to use an eGPU - which I was trying to do so I could hotswap my video card from my laptop to my desktop...)
CPU Upgrade option is still there but no XMP or other fine tuning OC controls. They show, but are grayed out and can't be interacted with.

I'm not seeing anything about this in the settings or manual.

What gives? Anyone know about this?
Might it be the BIOS version? Any recommendations on which bios version is best? (ordinarily I'd assume the latest, but...)

With an i5 6600k
I have some new memory coming (XPG PC4288 AX4U360016G18A-DW50) but currently it's Corsaire Vengeance LPX 16GB (2x8GB) (029E CMK16GX4M2B3000C15) - they should be running at 3000mhz C15, but it seems they are only running at 2133, which is a bit odd, no?
And no XMP settings or voltage control, etc...

I downgraded to some older bios and the settings came back. Currently running 22f.

They might be native ddr4 3000 sticks?? Check to see what cpuz says about the profiles in the SPD tab.

But I'm confused in another thread you have 3200 overclocked to 3600... and buying 3000 sticks now??
