Update - just done six hours of Kagari with no errors after knocking a few cores up; currently on -21,-21,-30,-30,-25,-25. Planning on one more overnight run (on Prime SSE Huge), and then trying to some games. CB23 score has gone up to 11,390, from 10,800 - this is why I undervolt😁 Answer from JMUDoc on reddit.com

r/Amd on Reddit: My findings with the new curve optimizer with AMD Ryzen Master
April 17, 2022 -

So I have done about 9-12 hours extensive testings.

--

You WILL have to know your max PPT, TDC, EDC else this is just waste of time doing it and you will just be using default values which give you more aggressive under-volt than you might had opted before manually before using this.

Make sure to set those values in bios before moving on else you will just see default values in there no matter if you pick auto oc, or pbo, this was the case at least for me it would not pickup anything else than default values in software until manually set in bios.

So go to bios set values for those and set everything else on auto in PBO menu.


Verify and run a test just to verify settings are applied like on this screenshot, you don't have to run a full test if your settings where not added correct, go back and do it again.

My 5900X can handle these

PPT 185

TDC 125

EDC 170

Screen after completion..

Video running test being stable for now and screen from HWiNFO just after finished tests.


Setup

5900X B0 Stepping early unit, not first week tho.

Asus x570-I ITX - Bios 4204 with AMD AM4 AGESA V2 PI 1.2.0.6b

3080 FE

16GB F4-3600C15-8GTZ

SF600

All in a loque ghost s1 case with some vector EK cooling setup on all parts.

All this was done by upgrading to latest bios, resetting bios to make sure no old values was stock and I only touched RAM timings with and dram voltage and PPT, TDC, EDC, PBO scalar x10, overclock 200mhz, rest was injected by ryzen masters into the bios settings after hitting apply.


Overall AMD have done a amazing job with this, even noobs can overclock and undervolt proper now 10/10 AMD clap clap

Ryzen Master - Auto Curve Optimizer | Hardware Canucks

r/AMDHelp on Reddit: How good is Ryzen Master's Curve Optimizer automation?
July 24, 2023 -

Had my 5600 for nearly a year, now, and want to have a bit of fun with it. Going to try some CO, but I'm not in a position to use the "manual" methods - how good is the automation routine in Ryzen Master?

Has anybody tried it? Does it come up with stable values? I'm not bothered if it's too conservative - I'd rather it be 90% of the way there, and stable, than split hairs for the last ten percent.

I'm prepared to test with OCCT core cycling, if need be.

Ryzen Master - PBO Curve Optimizer Control - Configure in Windows Now! | [H]ard|Forum
April 20, 2022 - I suspect the settings Ryzen Master spits out for CO use are a very good starting point. I wouldn't take them as 100% stable in all situations and definitely require more stability testing. However, it should shave off quite a few hours of testing if you were doing a proper job testing CO settings in the first place. ... Dialing in per-core curve optimizer settings can be tricky.

r/overclocking on Reddit: Ryzen Master curved optimizer.
October 20, 2022 -

Wasn’t aware that there was an auto curve optimizer until now. Testing to see how well it works but the estimated time start to finish is a little over an hour 😐

----Update--- Mobo - Asus X570-i itx CPU - Ryzen 5700G

After waiting for this to finish I ran a Cinebench R23 multicore and got a score of 14385 (don't have a screenshot unfortunately). Following that I enabled PBO within Ryzen Master and waited for the restart. After Ryzen Master relaunched following the restart I ran Cinebench again and received a score of 15211. This was all while boosting to 4.65 on all cores at 1.31 volts. Before the Core Optimization with PBO turned on CPU would boost to 4.6 and almost immediately go to 85c and now it has not gone above 73c after the 10 minute loop within Cinebench. For anyone who has not tried or is skeptical, this utility works, at least for me it has produced measurable results. Note - Ryzen Master was running in the background for both runs so it's as close to apples to apples as possible.

I want to set up Curve for my 5600x, but when I start optimization through RM, then EVERY test for some reason gives me one number (-25) for all cores, even though I chose Per Core, what am I doing wrong? How to force RM to select numbers correctly? Sorry for my English, I'm from Serbia myself.

Question - Ryzen Master Curve Optimizer, how to know if it's really being applied ? | Tom's Hardware Forum
June 19, 2022 - The one on right side is just to perform chosen optimization and does nothing until you actually perform it. If you leave it at "OFF" and perform optimization it just returns settings to defaults, No Optimization. I kept on switching between Off, per and all core but none gave me good results, or not as good as manual settings in BIOS.

r/sffpc on Reddit: Ryzen curve optimizer
January 21, 2024 -

So first thanks to the few tips on the hardware choices, my terra build worked first time. 7900x, in eco mode, 32gb 6000mhz ram and a 6700x. All expertly built by my 9 year old, it was fun teaching about building computers.

I want to ask about this Ryzen tool that is supposed to automatically curve optimize. My system was stable in eco 105w mode, memory clocked at 6000mhz and the temps are cool - the heat sink cool to touch and ~40oC idle, all nice.

After the optimization finished I had to apply the settings it suggested -36. This made a bsod boot loop immediately after the sign in screen, kmode exception not handled. I had to clear CMOS to get back.

I confess even in my experience of 20+ years I've never really overclocked, I favor stability and don't like to push it if it's fast enough already. As I understand these curve optimizer settings aren't overclocking, but running at peak efficiency.

So what is the problem, the suggested settings are just way off? Do I even need curve optimization? I'm interested in cooler temps without changing the cooling solution and power efficiency.

I also read that we should have done curve optimization with a clear bios, I had eco mode (105w) and expo enabled in the bios?

How to use AMD Ryzen Master
December 12, 2024 - Overclocking is not the only thing you can do with Ryzen Master. In some scenarios, undervolting your Ryzen CPU might be a better option. Maybe you don't need any extra performance from your CPU, and simply need lower temperatures without a hit to stock performance. This is exactly what the Curve Optimizer section can achieve by automatically manipulating the voltage-frequency curve of your CPU.
