For all the Overclockers here, I just did some testing and came to the following result:
- 3.8GHz@1.36V + SMT on -> stable
- 3.9GHz@1.36V + SMT off -> stable
- 4.0GHz@1.47V + SMT off -> stable
So with SMT off you win at least 100MHz, but I don't think it's worth it, because more traffic has to go through the CCX (if the application is using all 8 Threads).
I'm using the Wraith Spire of my 1700 and I can see that there is no Problem in cooling it (it stays at max 72°C), but you need a lot more VCore to achieve higher frequencies.
I think the Ryzen is made for 1.3xV and that's why there is 1700X and 1800X, cause they can take a few more MHz at the same voltage.
- AMD Ryzen 7 1700
- G.Skill RipJaws V F4-3200C14D-16GVK @ 2933MHz
All in all, a email@example.comGHz with 1.3xV is the sweet spot (performance and consumption wise).
