Asus Tuf gaming 570x-pro (wifi) runs with a Zen 3 5600x CPU cooled by a Galahad 360 AIO. The graphics card is an RX 6800, paired with 32GB of GSkill TridentZ Neo 3600 F4-3600c16d-16gtznc. Storage includes two 2X NVMe WD 850 1TB drives. The case is Phanteks P500A and the power supply is Seasonice Prime PX0-850, rated 80+platinum.
I’ve been using this machine for about eight to ten years. Before that, I played on a gaming laptop with an i7 and GTX 970. Then I upgraded to a desktop with an OC AMD Black Edition CPU and a 500-series GPU. Recently, I’ve been overclocking my 5600x and here’s what I’ve achieved so far: 1.375V @4.75 for all cores, 72°C. My Cinebench scores are solid—multi 10,695, single 15,120 after the multi boost, and a single of 1,568. To reach a stable 4.80GHz, I need to push the voltage down to 1.45V, but only managed an extra 200MHz on my multi score. My friend noted it’s impressive at 72°C, but mentioned AMD might handle it better since they’ve boosted their i9 9900K to 5.0GHz all-core at 50°C. I’m aware that anything near 90°C is risky. I’m seeking advice, tips, and experiences from others, and wondering if this setup is worth the effort for someone in my position.
72 isn't too much of an issue. These are high-performance chips. I'm using a 360 AIO with eight fans, and my office stays around 18°C. My 5900X is running hotter than my old 8700K. Modern chips are built to handle self-overclocking as long as the cooling system works.

Try PBO using a curve optimizer, I know it can yield better outcomes. Experimenting might work, but 1.45V is quite high for a fixed setup, especially during continuous overclocking even if temperatures stay controlled. As a constant overclock, the CPU receives that voltage all the time, never resting. This leads to degradation—eventually causing instability and random crashes after a few months. If you revert to stock, it may stabilize with PBO, but performance won’t match its current level because the higher temperature forces the algorithm to run clocks even faster.
I've been experimenting with PBO and I think I might be making mistakes. Sure, in single or applications I get better boosts, but my score isn't that much higher. My multi-thread performance doesn't match my static clock. If you're curious, I can show some of my settings. However, just enabling PBO without tweaking any settings has definitely led to lower scores.
