How to tell if my voltage are too low, or too high?

We'll need more info before we can determine anything what are the system specs, current overclock settings and cooling capabilities. For testing the stability your going to need to run a stress test to check the overclock, if it fails it's most likely due to too high of a clock speed setting or too little voltage. Voltage depends on the hardware and what it can take.

It crashes at this frequency, but stable when frequency is lower, then voltage is too low

 

HWinfo says it's above 1.4V max or above 90C max, then voltage is too high and/or causing too much heat for the cooler to handle.

 

If it both crashes and runs too hot or more voltage than 1.4V, then your CPU is no good for this frequency and you need to drop it.

Ryzen 3 1200 @3,8Ghz 1,306V with Wraith Stealth on ASrock AB350M-HDV

Using Prime95 as stress test, and always getting failure on the 3rd thread after 20ish minutes running. 83ºC- is my max temp on torture. But never had a problem with Cinebench R15 with this configuration

Assuming you're ok with those temps, you can bump your voltage up a bit. Maybe .005-.010 to start with

Different stress tests give different loads to the system, sometimes you can pass a 12 hour stress test but fail a gaming load, not completely unheard of. That looks pretty good, I wouldn't push any more voltage due to the temps just being at the sweet spot unless you plan to add more cooling potential.

 

For ryzen a safe margin I would say for a daily overclock with very good cooling like a large AIO or custom loop would be 1.35V.
