I recently built a PC with a Ryzen 7 9800X3D, 32 GB of DDR5-6000 memory, and an RTX 4070 SUPER. I enabled EXPO and PBO, but afterward the system stopped booting and shows a DRAM error. I'm hoping to get it into a safe state so I can undo those BIOS settings. What's the right way to reset them?

You’ll need to reset the CMOS, which returns the BIOS settings to their defaults. Check the motherboard manual for the clear-CMOS button or jumper pins. The reset should be done with the PC powered off and unplugged.
Yes, removing the CMOS battery can also work. Unplug the system first, remove the battery for a few minutes, then reinstall it. Some boards also have a clear-CMOS jumper or button, which is usually the quicker option.
Turn off and unplug the computer, then use the clear-CMOS procedure specified in the motherboard manual. This commonly involves removing the coin-cell battery or briefly bridging the clear-CMOS pins with a metal screwdriver before restoring power.
Can I reset it by removing the motherboard battery, or is that a different process?
