Enthusiast-oriented motherboards often default enable Precision Boost Overdrive, causing higher power and temperature limits for longer periods. To run the CPU at “stock” you need to go in and disable that. Their default Load Line Calibration might be aggressive as well.
Which motherboards enable PBO out of the box? That’s crazy! I know that motherboard manufacturers set some sketchy default turbo durations for Intel CPUs back when Intel was cagey about the spec and let them get away with it, but I thought that AMD was stricter about such things.
