Fatal1ty Z170 Gaming K4 Overclock Not Saving

I just recently finished setting up a CPU that has a Fatal1ty Z170 Gaming K4 as the motherboard. I am using a Skylake i5 6600K (yes, it is a K for sure) as my processor and I am trying to overclock it in the bios. My issue is that whenever I change the CPU multiplier (to 44) and the core voltage to 1.35, I see the yellow text change in my UEFI, but when I reboot back in to the BIOS, the yellow text for the clock information is back to showing 3.5 Ghz instead of 4.4 Ghz. I am making sure that I am saving my configuration when I exit, but it's still not working. I have been able to change my RAM speed from 2133 to 2400, and that seems to save just fine, but the processor overclock won't.

Once you have done all that try the overclock again. That should get your overclock to work but if not post back with results.

Thanks. I checked the multiplier in CPU Z and it said 8 - 45 (I set the multiplier to 45, not 44), so I assume that it is working correctly.
