Hello,
I bought a brand new Asrock X370 Taichi with Ryzen 1700 and RAM CMK16GX4M2B3000C15 6 days ago. I added the new bios P2.40, but when i installed the CPUID TAICHI CPU-Z, CPUID HWMonitor and HWiNFO64 it showed a different voltage on CPU. I didn't tweaked anything else on bios except profile of ram, everything else have their default settings. I read somewhere that AMD says you don't have to add more that 1.335V (for OC), so when I saw 1.550V without doing any OC and used the default settings I got worried for my cpu, is that normal? Did I miss anything?

CPUID TAICHI CPU-Z | CPU: 1.344V -+

CPUID HWMonitor | CPU: 1.550V

HWiNFO64 | CPU: 1.5500V
