Overclocking at 3600 RPM with 4.725GHz and 1.45V is achievable.
Hey there,
I was feeling pretty bored today, so I decided to push my R5 3600 overclock a bit. At the time, it was running at 4.4GHz with a voltage of 1.165V daily, and I knew my chip was quite special. My aim wasn’t for a perfect 99% stable run, but just to clear benchmarks like R15, R20, or CPU-Z.
But in the end, I couldn’t hit both R15 and R20 because when the temperature climbed to around 85°C they would trigger an error and shut down temporarily. The only benchmark I managed was R15 at 4.65GHz with 1.375V.
Here are the details:

I wish this didn't talk about just voltage, because there's more to it than that.

What's safe varies between chips.
If you want to know your chips maximum FIT voltage, turn on PBO and max PPT, TDC and EDC and run a worse-case workload(Prime95).
Somewhat problematic is that, unlike Intel's cpus, Ryzen 3000 does not separate AVX instructions; on Intel mobos you can set AVX offsets, with AMD's, you can't.
Those offsets help with power consumption, because AVX really cranks things up.
The situation described varies depending on the load conditions. For lighter tasks, the CPU uses higher voltage and current but only through a few active cores. Under heavier loads, it switches to lower voltage and current across all active cores. When manually overclocked, users often find themselves consistently drawing low voltage and high current, irrespective of the number of cores engaged. This persistent high current draw during heavy usage may be linked to the issues some Ryzen 3000 CPUs experienced, leading to rapid degradation or failure within a short time. I acknowledge part of this, but I’m still trying to fully understand it.
The discussion touches on aspects beyond just voltage, as there are additional factors involved.
For determining safe operating limits, enable PBO and max PPT, TDC and EDC settings, and execute a challenging workload like Prime95.
A notable challenge arises because Ryzen 3000 chips lack the separation of AVX instructions found in Intel CPUs; while Intel allows adjusting AVX offsets, AMD does not.
These offsets are important for managing power usage since AVX significantly increases performance.
What cooler are you using to keep it cool? I won't find my FIT voltage since the worst-case scenario is max 1.25V. But people are recommending 1.3V as a stable and safe option. What a mistake. Thanks for the help!
