So i have a problem.. my ryzen 1600 when overclocked to 3.8GHz is working just fine @ 1.308v, but sometimes bus speed rises to too high levels and core speed jumps to 4.9GHz on all cores and immediate freeze. Only hard reset is an option. I have tried disabling c-states, adding more voltage, decreasing multiplier, using ram stock speeds and nothing is working and its driving me crazy. I can run intelburn test for hours, AIDA for hours, prime95 for hours and they give no errors or freezes. Just seems bizarre.. and this happens every time i play a game of cs:go.
Under full load everything is just fine.. this happens only when under a small load or idling. Temperatures are also very good.. 29c idle and 61c under full load max.. i have an 360mm AIO.
