Disabling boost works quite well. In gaming the max Vcore drops from 1.45V down to 1.0V, temps from 82C down to 62C and CPU power consumption is down 30%. The only drawback is a maximum speed of 3.7GHz but now that summer is here it's a good thing to dial it back. I've noticed that the 5600X slowly warms the room up during the day.

I recommend you try ECO Mode PBO. It's an awesome setting. Great temps and you still get high single core boosts.

eco mode is great since you can tweak the values further - its more like a template

Yeah I tried Eco mode but it doesn't seem to do anything. Same power consumption and temps whether it's enabled or disabled. I'll need to have another look at it to see if I can make some manual adjustments.

remember that other settings can override it, you dont want manual clock speeds, voltages etc

For those of you who say my rig is overkill at 1080p, you are very very much in the wrong. once you hit 120 fps there is severe diminishing returns, I agree with that, but even then most games I am trying can not break 80-90 on Ultra settings at 1080p, and this is with my 5600x oc'd to the max.

I just tried playing ghost recon wildlands, and got my *** handed to me. Had to lower settings to high from Ultra/very high in order to hit a nice 130 frames. Ideally, all my games would run at 120+ fps for the ultimate smoothness. Even an old game like Shogun 2 Total War is crippled in large scale battles and can't break 60 fps, once I lower settings its decent. But yeah... I am impressed on games like Witcher 3 though maxed out and 165 fps, its noticeably more immersive to me than even at 100 fps. just imo of course.

Looks like there's some interesting power saving updates coming too:

Ryzen 5000 Series Gets In The Undervolting Action With Precision Boost Overdrive 2

The Ryzen 5000 Series are about to get quite the boost with Precision Boost Overdrive 2 and Curve Optimizer in the upcoming AGESA.

Didn't see it, I just refer to whichever article I saw first. The Techpowerup article is much more informative though.

Update: New video from AMD

I updated the BIOS on my X570 Elite to F31j. I noticed stutter in game (War 40k Mechanicus ) i opened MSI Afterburner and saw huge frame time variations. I changed only two things from the default settings, undervolt by offset -0.03V and RAM speed to 3600. I loaded up user defaults, and all things were normal, i then reapply the undervolt and the stutter was back.
See the clip i made. Now i have the voltage on Auto again, all is good, but this is weird with the previous F31f BIOS i had no issues.
Could it be a bug in AGESA or something ? It is not big a problem for me, but any one else have this issue ?

Gents, a different question
Lets say I don't want to push my cooling to the limits yet (there's no use case that would make me CPU bound), but also I don't want to go all the way down to ECO mode, how would you set these 3 limits PPT (W) TDC (A) EDC (A) for 5800X to get most of it's performance without getting too high power consumption? Which one is the most important?
ECO sets them to PPT 87W, TDC 60A, EDC 90W, in benchmarks I lose less than 10% multi core performance, in games even less as single core boost seems mostly unaffected.

 

[Mussels]

just lower PPT if you want the heat/power consumption reduced, then you get the snazzy boost clocks without the smashing heat

Ok and current limits should stay on default for platform, since power limited CPU won't take as much juice anyway I guess, thanks!

Just started playing with the new curve optimiser... i feel like it's gunna replace manual OC'ing pretty fast

well, PBO limits are similar in a way and curve optimiser just adds over/under voltage control to it, at least this is how I understand this two features combined

undervolting per core, so you figure out which ones are better than others and tweak the volts

as soon as you lower the power to a single core, the rest can boost higher... lets you narrow it right in. I just need a benchmark tool i can lock to each core, i guess

Less than one year ago, all three of the household computers were Intel. Now they're all AMD Ryzens.

Both the Core i3 4170 and Core i3 6100 have been upgraded to Ryzen 3 3100's, and my Core i5 4670K was retired for the 5600X.

Probably sounds like a broken record at this point, but damn, AMD has come a long way.

No question about it , for me anyways

 

[Mussels]

With my chip hitting 5050Mhz and some people on other mobos reporting that you can change the +200 to +400, i'd rather stick with the curve than get stuck single threaded 500MHz lower

 

[Alyjen]

I know overclocking is an art so it doesn't have to make sense, but scores of ~6300 in CB R20 is less than 5% higher than you get from stock setting. If you can pull it with less power, and then plan to use it for professional work then I guess it's great, few % faster, for less $. Otherwise I'd play with it for a while and then forget.
If you use some more memory dependant benchmark (I like to use Geekbench for that) you'll see double digit gains by just setting your memory right

It really is and like most other forms of art, it takes skill, experience and some intuition.

 

[Mussels]

I wanna play with the curve more but i was getting crashes at idle not load, so its hard to automate that

Well, part of the issue is that we're all playing with beta version of this feature. It's still AGESA 1.1.0.0 while what was advertised by AMD was with AGESA 1.1.8.0

 

[harm9963]

Hit and miss with some system , par with Beta , but have to say, my x470 is performing beyond expectation , future BIOS will address issue's ,we hope .

5806 Beta PRIME X470-PRO BIOS 5806
1. Update AMD AM4 AGESA V2 PI 1.1.8.0 for new CPU support
2. It’s highly recommended not to update this beta BIOS when using AMD AM4 Socket for AMD Ryzen™ 3000 Series/ 2000 Series/ 1000 Series/ A-Series Desktop Processors.
3. This beta BIOS can’t be reversed.

One last attempt to pbo my 3900x before (at some point when i can get one for less than 600euros anyway) I replace it with a 5900x..
Last time i tried must have been 10-11 months ago.. good to see it's still not doing anything at all for this particular cpu.
