What is a suitable voltage for continuous overclocking?
Hello, I'm a beginner in overclocking and seeking advice on a safe constant voltage for my Ryzen 5 1600. I'm currently at 3.9ghz with 1.425 volts, needing stability while typing. I'm concerned about potential crashes after using Cinebench. Should I try a more stable 4ghz target at 1.45 volts or maintain my current 3.8 overclock below 1.4 volts? My motherboard is an MSI B350 Tomahawk, and I plan to upgrade to an H100i cooler later.
I think 1.45V is the commonly recognized upper limit for Ryzen processors, provided adequate cooling is available.
I recall seeing a suggestion from AMD about a range around 1.35V, but it's hard to find that now.
For myself, I prefer a clock speed of 3.8GHz at below 1.4V, though it wouldn't hurt to test stability at 3.9GHz with 1.45V.

1.45V probably won't damage your CPU, but it seems like you're experiencing unusually high temperatures with that setting on the stock cooler. The cooler usually handles around 1.3V well, which typically gives you stable performance at 3.7-3.8GHz. It might indicate a faulty chip or possibly a problem with the board.
Also, Cinebench isn't the best way to confirm stability, you should try Aida64 for a longer time (different people have varying views – personally I aim for at least an hour).
55'C Idle might be a bit high, but it makes sense considering the voltage and cooling.
Idle isn't critical, what's important is how the load temperatures behave.
After a good stress test, what temperatures are you observing?
