Marvel Rivals on my ASUS ROG STRIX Z890-A GAMING WIFI S Snow Edition after PBO optimization frequency limits feel shaky should backing up BIOS config actually preserve overclock gains or am I risking crashes

Marvel Rivals high frame battles PBO optimization makes frequencies wobble on my ASUS ROG STRIX Z890-A GAMING WIFI S Snow Edition I entered BIOS used AI Overclocking for auto profiles base frequency settled 4.0-4.5GHz range then manually backed up config. Reset tests recovered fast but temperature curves still swing 10-20℃. Voltage tweaks reined in power somewhat yet crash risk adds mental strain. Player feedback highlights stability gaps across memory kits I used compatible XMP for decent safety. Even with backup heavy team fights still drop occasionally. For this board overclock backup preserves gains yet real runs carry uncertainty when pushing limits.
