Most all bios menu's have a default option to restore back to original default settings. Also before booting from the bios menu after making any changes or not you are asked if you want to save changes.
I would save a default profile (with any base changes you make) in the BIOS, then save another one with the working overclocking settings, then use a third to make more changes to get it working fully.
Your BIOS may not support that, so you might want to write the settings down or keep track somehow.
