70c idle temps 3800x

Catlin · 18 Jul 2019 at 21:23

I can see my cpu is running at 1.4v constantly and is idling around 70c. Can anybody help me, I have checked most of the threads discussing this issue but cannot find anything that works for my setup.
I tried the MSI bios on a x570 board and cannot find a Normal cpu voltage setting to try. I have tried the power plans and cant see any difference.
Getting a bit worried running the system all day now.

You have no voltage options in the BIOS?

Of course but what should I be setting, As far as I know this cpu and mobo should be able to sit idling at 3.9ghz and then power up to 4.5ghz for a boost but it seems stuck on 4.5 no matter what setting i choose.
Would you recommend to drop it to 1.3v?

I just had a look at mine and it was doing the same exact thing, however my 3800X would actually go down to 36C more or lesson idle. The voltage was constantly between 1.44-1.49v. I turned off my keyboard's background process which controls the RGB and Macros, CPU voltage dropped to 1.031v automatically and now scales normally.

Check what you have running since it might be causing "wakelocks".

Interesting, I may take the cooler off and apply some proper paste not the standard one.

All those years people saying don't lag it on, might just be the thing to do for these chiplet CPU's. Let us know results if you do it.

Whater are you using? If the stock paste was a circular application or small rectangle, it's definitely worth trying a full spread with kryonaut.

go into Ryzen master and disable PBO. Your temps will come down.

THe chips are a bit sensitive to the needs of users it seems and keep voltage up in PBO.

I think we'll be seeing a bios patch before to long.

I stuck a blob in the middle and a blob in the upper right (on a 3800X). 30c idle 64c load.

for those with high volts, AMD are recommending lowering the minimum setting in the power plan. Just tried it and it's stopped my CPU idling at 1.45v

Is this in Ryzen Master? Mind sharing a screenshot of your settings?

It is from the reddit thread updated by AMD Guy Robert something

EDIT 7/18/19 As a temporary workaround, you can use the standard Windows Balanced plan. Edit this plan to use 85% minimum processor state, 100% maximum processor state. (Example). This will chill things out as we continue to work this issue. Your 1T and nT scores shouldn't change at all (+/- the usual run-to-run variance). This will preserve boost, retain cc6 core sleeping, preserve idle downclocking/downvolting, but make the CPU more relaxed about boosting under light loads.

Please note that it is totally normal for your Ryzen to use voltages in a range of 0.200V - 1.500V -- this is the factory operating range of the CPU. It is also totally normal for the temperature to cycle through 10°C swings as boost comes on and off. You will always see these characteristics, as they're intended, so do not be surprised to see such values.

Please do not undervolt the chip or set a maximum processor state of 99%. These are ineffective and/or detrimental changes.

We appreciate the reports everyone has provided, and they are helpful. I will make an all-new post when I have a more comprehensive update to share. Thanks for your patience. ♥

This is the one. Works great although I used the Ryzen power plan to 70% and it seemed to work for me.

Catlin · 19 Jul 2019 at 09:02

Last night I just capped the volt to 1.35 and it was running at 3.9ghz with seemingly no boost on and temps were idling around 40-50 trying out a few games it only ever went up to 65c which I am a lot mroe comfortable with right now but the cpu shouldnt be running like this. This is with PBO off, wondering if I put PBO on and cap the voltage it will boost at all? but I will play more with it when I get home today.

Have a read of this thread posted to reddit by an AMD employee

https://old.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/

Set everything to default/normal in bios including all voltages, activate ryzan balanced power plan in windows and close all monitoring apps apart from CPU-Z and ryzen master and see how you get on.

adrichardson81 · 21 Jul 2019 at 12:26

Try the Windows balanced profile - idle voltage dropped to about 0.93v for me from 1.475v

How does that affect performance compared to Ryzen Balanced?

lltfdaniel · 21 Jul 2019 at 12:45

My 3700x idles at around 50 c and am also concerned about the voltage as well.

That is with the stock cooler fan, that comes with the CPU.

My voltage is 1.4 to 1.5 volts when idle.

Voltage has nothing to do with why your idle temperature is so high. You have a bad mount.

Check hwinfo64.

P = V * I

If you have no load and therefore low current, P is low.
