Upgrading performance on my R7 2700 unit

Switching from 4GHz to 4.1GHz should improve performance, especially in games. You've already tried 4.2 and 4.3, and your B450 Tomahawk won't start unless you raise the Vcore to 1.45V—something you don’t want to do. With your Sapphire Pulse 5700 GPU and the RAM listed below, this change could make a difference.

Not worthwhile, only a 2% improvement in performance.

Monitor VRM temperatures with Hwinfo64. It seems feasible to reach around 4.15 GHz with a 1.4V supply.

remains quite expensive for around-the-clock availability

Use Zen+ at 1.38V to see how far you can go (like 4.15GHz, etc.). The difference won’t be obvious—just a few frames here and there.

I see your results match closely with mine, but it seems the B450 might be limiting performance. I didn’t win the silicon lottery with this chip, though. I went back to stock after being uneasy about 1.45v continuous operation. Now I just keep XMP active. You probably won’t notice much difference between the two speeds.
