Safe OC values for Ryzen 3600 in PPT, TDC, EDC
Safe OC values for Ryzen 3600 in PPT, TDC, EDC
Hey there, I've checked the search feature but didn't find what I was looking for.
Recently I got a Ryzen 3600 and using PBO added features not present on my older Ryzen 2600, so I'm curious about
safe PPT, TDC, and EDC values for an all-core overclock with PBO.
Some users on Reddit suggest staying under 90A, while Buildzoid shows higher limits for the 3600.
What about other options like PBO scalar, cTDP limit control, or package power cap?
You can check Buildzoid's settings in that video.
Ryzen (even Zen2) usually doesn't overclock all cores beyond its maximum boost speed. When you begin with manual all-core OC, adjusting the multiplier and voltage manually is more effective; PBO becomes less important. Due to the variability in silicon quality and other components, it's hard to predict the outcome. It's advisable to start with a multiplier around 4 GHz (41 multiplier) and then lower the voltage until you achieve stable performance. Once you reach 41.5 GHz, conduct tests to determine the voltage limits and temperatures. Check the Ryzen Master documentation—anyone who modifies it can adjust or lower its settings in the BIOS, which is safer than relying on others' results.
Thanks, but I'm already aware of this—I modified my Ryzen 2600 to 4.15GHz. I'm just not sure about these new configurations that the Ryzen 2600 didn't support.
Anyway, the problem is resolved now because I changed the topic, and I updated my Ryzen 3600 to 4.4Ghz @ 1.26v. It's running smoothly (passed 95 tests), cooler (8-10 degrees lower), and quieter. I got a solid chip from Buildzoid, which was from early batches with lower quality silicon; newer ones perform much better when overclocked.
I left the default values for PPT, TDC, EDC, etc., and achieved 4.4Ghz. If I adjust those settings further, I might get even higher OC, but for now this is sufficient.
My question was focused on these specific settings, not anything else.
Great outcome overall, though none of those parameters affect the red field when adjusted. I've already explored all the recommendations and additional options, but without noticeable improvements. Just one EDC issue showed minor effects, limited to specific BIOS releases while auto/PBO enhancements didn't help.
The only observation I made when adjusting those parameters was increased power usage, greater current, resulting in higher temperatures and fan noise at the same 4.4Ghz frequency. I didn’t attempt higher output since I’m not aiming to exceed 1.26v. It doesn’t matter whether I can achieve 4.5 or 4.6Ghz at 1.35v; I’m not focused on discovering the chip’s maximum output at the cost of its lifespan or performance.
The top 3600 chips can handle 4.5Ghz at my voltage, so I’m not missing much in terms of performance.
My FIT voltage under full load in Prime95 is 1.28v, which gives me a good safety margin at 1.26v.
I plan to test how low and stable the voltage can be with a 4.3Ghz output and evaluate the balance between reduced performance and improved temperatures, quieter operation, and less degradation (or none). Based on the outcome, I might consider using it for regular tasks.
If an MB has LLc configurations that might help fine-tune voltages slightly, brief voltage spikes won't cause harm or wear. Even with extreme voltages some BIOS options include auto, a value above 1.3v remains secure.
So far I've reviewed several articles and videos about overclocking the Ryzen 3600, and I can say that although initially it was thought a voltage of 1.325v or even 1.30v was safe after Zen 2, this has been proven incorrect. Many users who used those voltages experienced significant CPU degradation months later.
I’ll just share one link among the many on this topic:

Anyone can decide whether to accept or disregard this information. I prefer to stay within my safe minimum voltage and go higher for maximum overclocking. In my setup, the lowest safe voltage is 1.28v, my current overclock is at 1.26v, and with an LLC of 5 it drops to 1.206v under full load – these numbers remain consistent in Prime95 tests.
Theoretically, I could push it up to 1.28v in the BIOS, which would add about 50Mhz but also increase heat and noise, which I’d rather avoid.
I believe the optimal range lies between 4.3Ghz and 4.4Ghz for this chip, as it offers the best balance of performance, heat, and noise – something I’ll discover soon.
It's prudent and smart to strive for as low voltage (and heat) as possible, no matter which CPU and indeed any electronic device, can't dispute that.
At very beginning AMD was mainating that even 1.5v is not too much so MB manufacturers took it for granted and often set it to that maximum without any good reason. "Ha, see how stable is our MB" Lol, of course, until something goes wrong.
Personally I don't subscribe to that big and fast degradation of CPUs with marginally higher voltages as long as temperatures are decent. I'we been OC ing everything I put my hands on since early '80s, even by doing voltage mods when needed and never experienced no degradation in any form although some did smoke a little or more. Had more trouble with VRMs. None of Ryzens I kept more than a year and that's starting with 1600x,all more or less OCed with long stretches of time working in OC mode but adequately cooled but was wary of voltages over 1.4v which in most cases were not even necessary as OC ceiling was reached before or at that voltage and no added voltage would make noticeable boost. Before this one I had 2700x for about same length of time, mostly boosting up to 1.325v, normally up to 1.275 and no deterioration was observed. I found out it's more economical to just go for automatic boost and PBO than to OC. In case of this 3700x it's boosting one core up to 4.4GHz/ 4.290-ish on others at 1.325v as maximum. Manual OC with any acceptable stability only at 4.3GHz at same max voltage is about maximum no matter what else I do to it including up to 1.5v. Heat and power requirements even lower performance at such occasions. Pushing them higher unless cooled to subzero cooling brings no much more performance, battling only for frequency records to say nothing about how impractical it is. I also often use Power Plan (5/50%) to limit everything to up to 2200MHz a that's not even noticeable for everyday tasks. Voltage barely hits over 1v at those times, temps staying at practically idle levels.
Yeah. It's one of the top chips from its batch, from April 2019. I purchased it used now at a good price and I was aware of its original condition potential from the owner. That's why I bought it.
There are even better ones, newer models, that can handle 4.5Ghz at my voltage or even lower, you can find them on Reddit, there are some discussions about them.
