Yeah it was getting too unstable after the +177mhz so i had to bump the GPU voltage offset to 30% and power target to 114% and it stabilized. Who knows about the future tho? I might be rich I might be homeless but as long as these settings wont damage it then I can rest easy.Lowering the temperature may result in better average results as well. Undervolting with increased clocks can sometimes work as well.
Considering those sliders are within Nvidia specs unless you have tinkered with the BIOS or done a shunt mod, it should be fine long term. But how you define long term is another matter. I have a 3080 Ti as well, and I foresee keeping it active another 2 years potentially.
