Does an OCd chip reduce clock speed?
Does an OCd chip reduce clock speed?
I looked into overclocking and found out whether you lower the clock speed and voltage when not in use or only when running heavy tasks. I have an R5 3600 with Tomahawk Max and I’m planning to try this. Thanks!
OC on a Ryzen involves a complex adjustment process. The CPU adjusts based on voltage, temperature, and current levels. Reducing all three can actually improve boost performance, though only within certain limits. Optimal speeds are achieved by finding the right balance among all three factors; changing any one can reduce or even hinder boost.
PBO automatically manages this balancing act, making it much simpler than manual tuning.
Current settings are the most critical and often misunderstood aspect. Many focus on Intel approaches, adjusting speeds, voltages, and temperatures. However, extreme current loads are harder to define consistently.
regarding this, I haven't located Cool N' Quiet in the BIOS settings, and I've seen reports suggesting it might have been taken out by AMD.
P state overclocking allows you to maintain power-saving options if your BIOS supports it.
The 3600 model isn't really beneficial for overclocking, as precision improvements work well with adequate cooling.
The main reason to adjust manually seems to be lowering the voltage at higher speeds, since Ryzen chips often overestimate voltages at those frequencies (safely, not dangerously).

Ryzen supports up to 1.5V at idle or very low current loads, 1.325V at moderate loads, and 1.2V under extreme current conditions. The exact definition of an extreme load is unclear—does it refer to stress tests, gaming, or specific titles like CoD, BF5, CSGO, or Minecraft?
Many users push high-speed OC, assuming a safe 1.3+V, only to experience CPU failure within two years. Personally, I advise against manual tuning on Ryzen. It’s better to use PBO, PBO1, or PBO2 and let the CPU operate at its peak performance based on available cooling.
