How do I stop frequent VRAM crashes in Battlefield 2042 on Biostar A320MH PRO?

Battlefield 2042 crashed constantly with VRAM errors. I tried overclocking VRAM, which made it worse. I used the GamePP System Backup & Configuration Export Tool to rollback drivers. MemTest86 showed error rate dropping from 15/min to 0/min. Temps stabilized at 75℃. The system is finally stable.
