anyone got luck using curve optimizer on PBO2 (5xxx)?

I cant even get curve optimizer to work.. it is not stable for me

Moron tuber doesn't understand how to undervolt, makes a video as a blind leading the blind.

You misunderstood. You can certainly do it the way he's showing in the video, it's just that his video is riddled with misinformation as always (just like all his previous undervolting guides, some of which he had to take down).

He claims that @10:30 if you want to "undervolt traditionally" you need to lower all the other limits on the motherboard as well. This is untrue lmao. You can still set a negative offset while maximizing the VRM limits and still get an undervolt, the CPU will still be able to boost to its max clock speed if an app needs it. All the user has to do is to make sure they have sufficient cooling so that the CPU doesn't run into thermal throttling. He doesn't make this clear at all and shrugs off other methods and says his is the best, that's what blows my mind.

I'm also damn sure his undervolt of -30 is unstable in real world usage. Benchmarks IS NOT an indicator of stability, he however believes it is.
