It's a Ryzen, not an Intel. The performance differs, voltages are handled uniquely. Attempting to make a Ryzen act like an Intel damages it, which is typical for OC.
Intels tend to be more self-regulating. They perform better with higher input and maintain speed as long as temperatures stay within safe limits. A Ryzen operates differently; it's designed to run efficiently without being forced beyond its limits.
Ryzen chips are built for efficiency—making them more capable when optimized. Reducing voltages brings down temperatures, enabling the Ryzen to sustain higher performance for longer. In contrast, an Intel struggles with power limits (PL2 down to PL1 at Tau), whereas a Ryzen continues to operate effectively.
For instance, my 3700x runs better at 4.29GHz all-core and 62°C compared to 4.4GHz all-core and 84°C without any PBO, since its maximum performance stays under power constraints. It naturally runs faster due to lower heat, even without voltage adjustments.
Cutting voltages to the absolute minimum for stability helps reduce temperatures, but achieving this requires Intel-level optimization. The best approach is using a powerful enough cooler and adjusting voltage offsets to the lowest possible working level for Ryzen.
Employing an offset enables the CPU to operate with a lower vCore at reduced speeds, is correct.
4.2GHz @ 1.175V sounds quite impressive. If that works for you, it would be a clear success. Remember to save your settings as a profile in your BIOS for easy access later.
Whether you aim for lower voltage depends on how much extra time you plan to invest in testing.
Additionally consider OC the RAM, which should assist with the 3100 delay between CCXs and significantly reduce latency.
Are the CPU core voltages within typical ranges? I need to check the photos. The values are between 1.155 and 1.177, with an average of 1.167.
