PSA: If you’re wondering why your 5900/5950x is running hot on idle/gaming, it’s the stupid Ryzen balanced power plan which sets CPU to 90% minimum.

I just spent 2 days repasting my cpu, dusting cooler, trying different fan orientations and almost purchased another cooler before realizing the stupid Ryzen power plan that comes with the chipset drivers sets the CPU min percentage to 90%, so when I open chrome I see the 5950x spiking to 100W power usage....

CPU temps dropped from 80C in Battlefield to 70C after changing to the balanced power plan from windows. No change to Cinebench scores.

I'm running a Cryorig H7 which is like a mid range CPU cooler (performance is equivalent to the NH-u12 ish or a 120mm AIO.)

Edit: Power saver plan is even better for my use, CPU temps are < 60C during gaming. Single thread score is unchanged for CB, but multi thread score starts off low then under sustained load is unchanged. (The scheduler takes a longer time to take up all the cores)

You should update your chipset and the Ryzen balanced settings will disappear. I thought this was a bad thing and kept updating my chipset thinking it wasn't installing. When I did some research found out that they took it away on purpose and windows balanced is the optimized setting for ryzen 5000 now.

I'm using a clean windows install with drivers downloaded from amd.com for b550. They're still there.

ID: h1zkq4m

Weird now that I think of it I feel like mine were there for a bit and then magically disappeared one day which started my confusion.

ID: h207qqw

Indeed. Oldest requirement in the book update your drivers cipset need love to;)) I don't care about my 38 C idle or 50 ish gaming when i use my 5900x.

You're not supposed to use the Ryzen specific power plans anymore with Zen 3.

ID: h1zjf8y

Yeah, I've installed the chipset drivers and the Ryzen plan doesn't even show up anymore.

AMD officially said to use Windows Balanced on 5000 series from now on a while back

ID: h210l29

What about 2000 series? Should I use it?

ID: h214d5q

Yes. Any series below 5000 should be on Ryzen Balanced or Ryzen High Performance

Ahem *Clears Throat*

How exactly did you get the Ryzen Balanced power plan when these plans are obsolete for Ryzen 5000 series and the chipset driver does not install them?

ID: h20rw9e

I can give you one, terrible, but for whatever I can tell turns out to be highly accurate far too often...

because windows.

I need to check this when I get home. I had no idea you weren't suppose to use the ryzen plans anymore. Thanks for this discussion thread!

ID: h1znssc

reinstall the chipset drivers as well from amd.com

ID: h206zwt

I didn’t know this either — should I reinstall ryzen master or the cpu drivers? Or both?

Ryzen balanced plan shouldn't even get installed for Ryzen 5000 series unless you are re-using an old windows install from a prior generation Ryzen chip. When the chipset driver installer runs, it queries the CPU model, if it's Zen 3 it should not install the Ryzen Balanced plan.

8 : Anonymous2021/06/16 16:37 ID: h1zhmnn

You can use balanced mode that windows comes with the min cpu there is 5%

ID: h20fbp8

FWIW, after updating my chipset drivers, I saw that the balanced power mode min cpu is at 0% instead of 5% prior.

9 : Anonymous2021/06/16 17:51 ID: h1zrzqg

I tried and indeed that's what it does.

I'm gonna keep it in power saver mode and see how it behaves.

We have a heat wave now in Europe.

EDIT: Power saver really hurts gaming performance. Back to High performance.

10 : Anonymous2021/06/16 18:13 ID: h1zv32s

Dont forget setting the power supply control to "low current idle" in bios. That makes my CPU run down to about 0.2v sleep all cores

11 : Anonymous2021/06/16 19:05 ID: h202bs7

Zen 3 does not use ryzen power plans. It is for zen2 and below. If you install the chipset drivers it does not even install it for zen3. If you have it installed on your system there are 2 possibilities.

1- You have upgraded your system with zen 3

2- Something went wrong during installation.

You should not use ryzen power plans. AMD explained it with the launch.

Even with my 2200G I'm always using Power Saver mode + Radeon Chill and a good undervolt of my RX 580. Better for the planet and my electricity bill, I don't really care about high framerates at all

ID: h20ehy1

Better for the planet

Nothing you do will make a dent in the 33 billion tons of CO2 every year that 70% of are solely due to 100 corporations. Your local power plant probably doesn't scale up and down in generation, it just makes a flat amount of power, which either goes used or to waste heat. So you saving a few watts is just putting it to waste.

and my electricity bill

Running a 2200G at 100% 24/7/365 would only cost you 5 dollars a month. You probably pay $2 a month using it normally so what's $3 a month to you?

ID: h20wzrm

I'm not saying it's much, but why not do it? There's literaly isn't any drawback to it since I'm not chasing after high framerates. Even a small win is a win, it's far better than doing nothing.
And btw the argument of "I won't change my behavior because someone or something else is doing much worse than me" is bullshit.

ID: h213180

You're right.

13 : Anonymous2021/06/16 20:37 ID: h20f4b0

Thanks everyone, I updated my chipset drivers prior to upgrading to Zen 3 thinking it would apply universal settings. Should have figured to just update drivers after the upgrade. This solves the high idle temps I saw the entire time. Exciting stuff.

I'm using an Asrock X470 Taichi for anyone who's curious.

Hoping to see the same improvement in gaming temps as OP.

Should I be worried if I have my 3900X running using the 1usmus power plan?

ID: h1zvayv

Not worried.. but it may not even do anything anyways

ID: h20j9pg

Usmus power plan is fine

16 : Anonymous2021/06/16 18:03 ID: h1ztoss

Very interesting. Anyone have links to sources with more info? I at some point just set the power plan to "high performance" and left it assuming that was optimal since cooling hasn't been an issue.

5950x under an ALF2 280mm in push/pull idles around 30C, looks to be peaking at about 76-78C under multicore cinebench r23.

ID: h202e5u

What score are you getting on that r23 multicore at those temps? I have aircooled my 5950X and it goes to around 84 or so on r23 multicore and gets around 28,4k score at that. I have yet to do the curve optimization so that should help it a bit (the score mostly as it seems power limited, not temp limited) so the curve optimization should just increase the freqs until it faces the power limit again.

Nothing to write home about, PR'd at 29158 multi and 1601 single at the moment. I've pretty much abandoned pushing my OC until agesa 1.2.0.3 in hopes that I can move the IF further. Relatively minor tweaking with CO/PBO2

17 : Anonymous2021/06/16 19:09 ID: h202z2b

Try these bios settings and keep it on balanced.

2 CPPC settings to enabled Global C States enabled PSS support enabled Set PSU to Idle Low power.

If not there are a few custom power plans for ryzen that you can install.

18 : Anonymous2021/06/16 19:19 ID: h204aqo

Well there's your problem in the title... you have a power plan installed for ryzen which shouldn't even be there in the first place with a 5000 series cpu.

I've setup a pile of ryzen 5000's in the last few months and i've never seen the chipset driver attempt to install any power plan on these systems.

19 : Anonymous2021/06/16 19:38 ID: h206zt5

Does this have anything to do with Minimum processor state in Windows advanced Power Settings?

Mine was set to 100%. Though I idle below 40C so not sure.

20 : Anonymous2021/06/16 19:40 ID: h2078ju

My 5950x idles @27c with a AFii 360 mounted as intake in push/pull. My "old" 3900x with same aio idled @23c. Pretty insignificant increase especially with +33% extra cores.

21 : Anonymous2021/06/16 20:33 ID: h20emnc

Min 5%

Max 100%

22 : Anonymous2021/06/16 23:27 ID: h2105a8

There was another guy who showed that dropping the CPU power from 100% to 99% drops your temps significantly. You can try that my 3900x was doing low 60-70c with nothing on, and tweaking it with that suggestion has it idling @ 52c, I've currently got some chrome tabs open, playing YouTube videos and reading books and I'm averaging 55-60c.

23 : Anonymous2021/06/16 20:24 ID: h20defi

Well for one you shouldn't even be using that power plan...
