Can someone familiar with Ryzen Master in Windows, using it with a 7950x 3D or similar, tell me the difference between tweaking an undervolt curve optimized setting within the Ryzen Master, verses going into the Bios and setting it there with the curve optimizer settings, which the latest Bio revisions, going back a few seem to permit? Appreciate anyone who can shed light on the differences as I have used both and am not sure how the interact with each other if setting in Bios then running our curve optimizing in Ryzen Master w/Windows 11. Regards, James

I just upgraded from 3600 to 5800X and I am really happy with it but I want to undervolt it since I want lower temps. Now I am really confused if I should use Ryzen Master Curve Optimizer or should I do it from the BIOS settings under AMD Overclocking...

Thanks in advance!

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

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

Do you wish to do it your self grab latest version here

(I have a 7950x) So i downloaded ryzen master to run the benchmark that supposedly finds the best pbo2 negative offset for maximum efficiency gains and it gave me all cores -30. the problem is that i enabled that in my bios but it is not stable at all. I found that it was because i had a specific option enabled that let my cpu boost to 5.7ghz in medium loads instead of 5.5ghz but i want a way to retain the medium boost while also reducing the voltage as much as possible. does anyone have a link to the most detailed possible ryzen undervolting setup? thanks

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.

To summarize, I downsized from a Lian Li O11 Dynamic to a Lian Li A3.

All same components, only motherboard change:

Motherboard - (was) AsRock X570 Steel Legend -> to -> (currently installed) MSI B550m MAG Mortar Wifi

CPU - Ryzen 5800X3D

Cooler - Corsair H150i AIO (360mm)

Memory - 4x8gb Acer Apollo DDR4 4000mhz CL17

GPU - RTX 4080 FE

PSU - EVGA Supernova 1000

etc.

I downsized my PC and went from an AsRock X570 Steel Legend to a MSI B550m MAG Mortar Wifi.

Before I could apply Curve Optimizer settings either through the bios or Ryzen Master in the Curve Optimizer tab on the AsRock X570 mobo. Results were great with all core boost stable at 4.425ghz at 72C, and CPU scores of ~5500 with 3DMark 4K TimeSpy.

The MSI B550m mobo has Curve Optimizer settings in the bios but I believe it isn't applying. Reasons being Ryzen Master no longer shows the Curve Optimizer settings tab, as well it states that Curve Optimizer is "Off". And now I can't get a 3DMark 4K TimeSpy CPU score above 5100. As well my temps are higher nearing 80C. Curve Optimizer in the bios set to "Auto" (there is no off option) and the scores are the same.

I am at work so I can't grab a screenshot of the ryzen master screen but I will when I get home.

I Submitted a ticket with MSI, hoping to get an answer, but if anyone has any insight I'd love to hear it.

✅ I already did the "Automatic Optimizer", it took about 1h 45m to complete, then it restarted.

✅ If i see this screen, this mean it's applied?

✅ Because if i restart and go to the BIOS, i don't see any changes in the CO.

✅ Also, i can close RM and the CO will still runing right or need to keep it opened?

✅ And for last, i should activate Max CPU Boost Clock Override?

Thx in advance!

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.

I'm running a 5600x and I've gone into my BIOS (Asrock X470 Taichi) and have PBO set to advanced with max boost clock at 200 and I've tried PBO Limits set to Manual, auto, motherboard and disabled. With it set to motherboard or manual, the home page on Ryzen Master displays values well above what it says on any settings I try to change. It shows a PPT of 740, 480 TDC and a 650 EDC. When I go to any manual settings, my max is 76/60/90. No matter what I set in BIOS and what the home page for Ryzen Master says, those are my limits on anything I try. As far as I know, I'm supposed to be able to change these, right?

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?

Hey guys, I was messing with the CPU speeds and trying to Set up PBO/ Overclocking. Both the Ryzen master software and Bios has the opportunity to change the clock speeds and overclock, wondering what if best to change it on, should I change both? When I change one it works, but the other one doesn’t change… thanks
