My new i5-7600k is running at 4.45 Ghz. I haven't changed anything on BIOS. The turbo speed for this CPU is 4.2 Ghz and stock speed is 3.8 Ghz. Both task manager and CPU-Z show 4.45 and sometimes even 4.49 Ghz with multiplier of 45 and ~1.265V. The speed stays the same with idle or gaming. Should I be worried or thankful?
