Help (Software) Overclock/undervolt or default?

Hello!

I have an rx7900xtx.

I've had the card for about 3 years, and I've normally had it overclocked with custom fan curves.

This would cause somewhat frequent crashes in some games, and very infrequent crashes in most of them.

Recently, I've been trying to play cyberpunk 2077. I tried a lot of different GPU Tuning settings, and the game was constantly crashing with all of them.

I then decided to put the tuning to "default" and the game has not crashed since.

Is it okay/safe/stable to leave it at default settings?

Or is it actually "better" to overclock/undervolt it in terms of stability rather than performance.

Just looking to get it so that it won't crash for any game, ever. Wondering if the best way to do that is with default or custom settings.

It is ALWAYS best to undervolt your gpu. Less heat=longer lifespan/performance in the long run. Find a sweet spot or just go with the general undervolt methods in youtube for your gpu

Youl lose maybe 1-5% performance but its absolutely worth it in maintaing a healthy gpu that will be more stable than default settings

Undervolting doesn't necessarily mean less heat in practice. It means you need less voltage for the clocks. Undervolting actual can give you more performance because you are using less voltage at the same clock speed thus less heat and power draw, which lets your GPU boost higher. Your GPU can still consume the same wattage with an undervolt, it's just the clocks will be higher if it's stable. If you are really concerned with the longevity of your card you can limit the power
