This problem only affects FMA3 instructions, which are optimized for Bulldozer, Sandy Bridge, Haswell and Skylake processors but not for the AMD Ryzen Zen microarchitecture and therein lies precisely the problem. AMD has already confirmed the problem and it will be fixed by updating the motherboard firmware. For now it seems that the problem is caused by a problem related to the power management of Zen FPU units, this would explain that overclocked processors are not affected by using more power for their operation.

Let's not forget that the Zen microarchitecture has been designed from scratch making it a completely new product, so it is to be expected that there are some drawbacks to solve so that everything works in the best possible way.

In this case you can also wait to buy a motherboard with a more updated firmware and free of the problem.
