Hi there!
After working for a little, i found the best settings to overclock my Palit 5070Ti Gaminpro-S.
Luckly, it has a really good dissipation system and i keep temps around 70/75°C under heavy load.
With overclock, i gained a really sweet 10.1% boost in performance, in 3440×1440 (heaven benchmark, from 283.6fps to 312.3, nearly 30fps improvment)! Really happy with those results.
Overclock:
+420mHz
+2000mHz
No undervolt
