Hello,
Finally got my 1700 but right at the start faced very strange problem. CPU-Z shows that core speed is only ~1550MHz. I have tried without overclocking, without any power saving options, no Cool&Quiet or any other extra CPU features. Bios shows that memory is running 3200MHz and also 3700MHz CPU when clocked, but everytime I boot to Windows10 CPU-Z, MSI tools, Ryzen Master shows only around 1550MHz. I have tried to use Ryzen Master for clocking but it doesn't change the situation. CPU temperature is around 40C and all voltages are set to auto on BIOS. Installed fresh Windows twice. Windows shows in System information that the processors is 3,7GHz but when tested Cinebench got terrible bad score ~500. Am I just plain stupid not to understand something or where the problem is?
