I also use curve optimizer and PBO power limits for all games. Raising the power limits is easy, and I’d suggest to to that route first. Undervolting with curve optimizer is time consuming and would only recommend it for advanced users, as it can cause BSOD if done too aggressively. Nevertheless, I’d highly recommend using a user tool called CoreCycler to help test for initial undervolting stability. It’ll test each core and tell you which one throws an error. The cores that throw an error need to be undervolted less.
