I'm confused here. When overclocking I need 1.45 v to maintain a 3.8Ghz stress test on my Ryzen 5 3600x CPU and to maintain a 4.2 Ghz stress test I need 1.25 v. I was under the impression that I would need higher voltage to maintain a higher clock speed, but I'm seeing just the opposite. Temps remain 70-75C for each level on the stress test. Cinebench has been my stress test program. Should I be using something different?
