Heya, those problems are an indicator for hardware problems. But it is not easy to track them down. FF14 is a real princess and needs 100% stable hardware. And undervolting of the GPU can cause instabilities. So i would not du that.

I would start with RAM tests like memtest86. Maybe it can detect something. An old PSU can also cause those instabilities. The Nvidia Ampere series is very PSU unfriendly. Maybe setting the power limit to 70% might help etc.


Cheers
