Boot Failure after changing BIOS settings

[Zaxi]

Hi.
My computer build consists of a Gygabite X99-UD4 and a 5820k. I think these are the only parts associated with the problems.

Earlier this week, I was able to over clock my CPU to a core ratio of 45 and a voltage of 1.3. Today, for some reason, I can't make any changes to these. I even set all of what I changed to what it is at default and when I boot, the error A9 flashes on my screen and I'm prompted to restore optimized defaults and reboot which is the only way I can get my computer to start. Please help? Thanks

once try removing the CMOS battery, turn on the computer and immediately turn off the computer and put the battery back in and then turn on the computer and try to boot into bios and then check the settings , choose load default settings once

that does the same thing as when I restore everything to the optimized defaults. I still can't change anything in the bios without getting that same error

after the error and the restart are you able to get into windows. ? if yes then try doing an bios update...
