Ryzen 5000 overclocking guide
You're considering a big upgrade from your old R7 1700 to a 5600x. It's smart you're thinking about overclocking, especially since you've had success with it before. The idea that modern chips hit a ceiling is common, but it depends on your specific setup and the chip's capabilities. With PBO enabled and your chip already running smoothly at 4.6GHz, pushing it further might be possible—but you need to be cautious. Adjusting voltages can help, but it's risky if not done properly. Make sure you understand the risks and test changes gradually.
You can experiment with PBO, the curve optimizer, to achieve a slight improvement (a few percent) while reducing the heat output slightly. It's probably not essential at this point. Just apply the newest BIOS, install the latest chipset drivers from AMD, enable Above 4G decoding and Resizable BAR (Smart Access memory, SAM).
