I have an Aorus Master, and had this overclock: 850mv +120, then +230 until 1060, and flattened after that – image 1.

I thought this was stable, as I've been playing Black Myth Wukong for about 10-20 hours with no issues, but just had a crash (nvlddmkm, so I'm assuming it's just unstable).

Went back to Afterburner and decided to add 2 extra points; following the exact curve: 1065 and 1070 – image 2. I was wondering if this is what people mean by adding more voltage to unstable overclock, or should I be bringing the entire curve down?
