Running at 4.8GHz at all times is completely pointless and a huge waste of power, there's no downside to allowing the CPU to idle at 1.6GHz and more importantly he's disabled thermal throttling which isn't too smart since that's how the CPU protects itself from overheating.
I'm not running 24/7 at these settings, just testing what the CPU is capable of. For 24/7 everything is enabled again lol
