Does lower your powerlimit and core clock reduces the stress your gpu vrm and stuff takes?
Lowering your power limit and core clock will reduce the amount of stress on your GPU’s resources, yes. Depending on algorithm it could even improve/not affect your earnings. On any algorithm that Salad uses that isn’t KawPow, core clock doesn’t matter and can be underclocked with no decrease to performance. This is usually the same with power limit but it depends from card to card and should be tested to see what works best for you.
No like I mean the Capacitors chokes vrms does lowing coreclock and powerlimit help prevent them from being damaged I heard about a game bricking cards because it over works the vrms stuff and I don’t want that happening to me
