Overclocking settings are not remembered on restart.

Level 7
I have an old Asus ROG G752VY (i7 6820HK, from 2015) laptop and at one point a long time ago I used the Asus ROG Gaming Center software to overclock it. It was set to "Extreme" in the "Turbo Gear" section. I left it on this setting for years and recently I wanted to change it back to the "Standard" setting to reduce power draw. When I change it, the CPU does start to use less power and it clocks down, as expected. However, after I restart the computer, the settings don't appear to be saved. It shows up as being back on the "Extreme" setting every time after I restart.

Considering the software is changing the clocks for the remainder of the time the laptop is on after I change it but the setting simply gets reset back to extreme up on a restart, I assume that the setting simply isn't getting saved somehow.

I don't know where this type of configuration is stored. I assume it is somewhere in the BIOS, but correct me if I'm wrong.

Why isn't the setting being saved? Could it be the the BIOS motherboard battery (CMOS, I believe it is called) is dead? For reference, I also can't save any other configuration changes I make in the BIOS. For example, I tried to change my default boot drive (there are two SSDs in there), and the configuration change in the BIOS would not save.

Nobody has any ideas?


Being an old laptop I'd definitely point my finger at the bios battery.
