With the stock cooler on the 2600 (wraith stealth), I believe 4ghz is roughly the best you can achieve. The built-in cooler is decent relative to Intel, though it remains quite compact. Adding a quality aftermarket air cooler would push the target closer to 4.2. The challenge with aligning the 4.25ghz clock of the 2600x lies in the fact that only one core runs at that frequency. Therefore, if you push all cores, stability might drop at higher speeds. This is why, for gaming, AMD CPUs tend to lose some speed when overclocked since most titles benefit more from single-thread performance than from multiple cores.
It might vary based on the cooler, the CPU's performance, airflow within the case, and room temperature. To some degree, the motherboard also plays a role. You'll need to test it out.
