I have the Ryzen 7 3700x, I used to run it using CTR at 4.45Ghz in sc and dc tasks, 4.4Ghz in 4c, 4.35Ghz in 6c, and 4.2Ghz all cores.
After that, I locked all cores at 4.1Ghz at 1.250V, and literally, I didn't notice any performance drop over the above frequencies in daily tasks and games, it runs much cooler with locked voltage as there were no more temperature spikes.
I will take this every time over a boost in frequencies that won't offer any performance benefit but results in a hot chip instead.
