Ryzen 3 1200 OC voltages at 3.8ghz and 3.9ghz?

What is a good safe voltage for these speeds? Preferably the safest voltage that will have the lowest heat output as I have low airflow in case.

Also, will disabling SMT mode do anything as the 1200 isn't using multiple threads per core?

 

Thanks!

There is a upper limit, but no lower limit. The lower the voltage, the less heat is pushed out. That said, at 3.8GHz most chips use about 1.3V to keep stability already. If your system is that hot, probably lower the clock speed further to 3.5GHz for example, and try 1.25V and lower.

Yeah I've tried 1.3 at 3.8ghz but was too hot (I think you saw my other post) but thanks for the assistance!
