AMD Ryzen 7 5800X High temps workaround.

Hello, I've recently finished up my gaming PC and I have a problem with 5800X, its pretty hot. I've done some research on the internet and apparently out of all cpu's from the new series, this one is specificly 15-20 C hotter than the others, sadly. Currently I'm playing WoW, with max settings and the CPU temp is around 70 in world and 65 ish during raids, and that for World of Warcraft which is not the most demanding game out there, I didn't had time to test it in other games. Considering my case is Fractal R6 Define edition, I've replaced the stock fans with 3 noctuas and the CPU cooler is also noctua, NH-U12A, basicaly my cooling is pretty high-end, hitting that these kind of temp is pretty bad In my opinion. In cinebench test, with out of the stock settings and with fans running at 100%, the temps I get are around 84-85 C, which is insanely hot in my opinion, considering that 5900X is a better CPU, I've read on the interent that is hitting in cinebench around 69 C......

So, to solve this, because I don't like having my fans running at 100% all the time, is too noisy, I want to lower the CPU temps by other means, I've tried to downclock my CPU basically and I've got the results I wanted in terms of temp, by using AMD Ryzen Master and by BIOS, but there is one problem. Doesn't matter if I use Ryzen Master or BIOS to reduce the frequency and voltage for my cpu, if I change the frequency by any value, the frequency then remains stuck at that value even in idle. Running at 4,5GHz in idle, seems pointless to me and I don't even know if that a good thing to have your CPU running constantly at that maximum speed you set it. I've watched Jaytwocents video about undervolting and underclocking and the only thing he mentioned about this, is that you should have your power plans in windows to balance, but mine already are and the frequency doesn't want to drop to anything lower than I set it. 

So is there a way to fix it? Can I only set the maximum CPU frequency that it can reach, for example I want to set it to reach max 4,5GHz (but not remain stuck at it, even in idle) so I can lower the voltage and thus getting lower temps?

Re: AMD Ryzen 7 5800X High temps workaround.

Hi, I'm not absolutely sure if this will work, however, according to AMD, with the latest Chipset drivers, the power management is now handled by Windows 10 alone (on the last to versions, 2009 and 20H2), meaning, power plans will no longer show the custom AMD ones.

Try setting your powerplan advanced settings:

 

Settings > System > Power & Sleep > Additonal power settings > Change plan settings (on current active power plan) > Change advanced power settings > Processor Power management.

 

There you can set the Minimum and Maximum processor state for the CPU, I believe that will only work if otherwise in BIOS and/or Ryzen Master is set all to defaults, no OC or undervolts.

Let us know if that helped anything at all 🙂

 

Unfortunately not able to verify this for you, but I have a 5600X that I leave at all stock settings, inclusive the Power Management. Changed my settings to check and worked for me or at least could see the difference on min/max clock and temps.

Re: AMD Ryzen 7 5800X High temps workaround.

Here is a screenshot on how it looks once I downclock it.


Basically, as you can see I've set from ryzen master 4,5ghz with 1,375V, which is stable, thats not the problem. But as you can see from 4 different softwares, they all show that the freq, is stuck at 4,5ghz, not lower or higher, in idle.... Also the power plans remain the same as with default settings, 5% minimum and 100% for max. Dunno why core temp is showing 3,5ghz, that clearly has to be wrong, but what it is interesting is that the ryzen master shows different values from the others. I dunno if this is a visual bug for other software's, because I used ryzen master to downclock it and could be the case that only ryzen master shows accurate freq after you do that, but I don't think thats the case, because even if I downclock it directly from bios, not from ryzen master, the results are the same, everything is shows that the freq is stuck at 4,5ghz....

But even if ryzen master is the only one accurate, I've never seen a CPU running at such a low frequency, is that normal?? I legit don't know because so far I've only used task manager to check current frequency.

Any other ideas? anyone else had this problem?

EDIT: That AMD Ryzen Balance power thingy that you have selected in the power plans, doesn't show up to me. I don't have it.

Re: AMD Ryzen 7 5800X High temps workaround.

You have not downclocked at all.

4.85 ghz is single core max clock speed
But under all core load around 4.53 ghz is normal. Lower if power or temp or something else restricts it further

So you're 4.5 ghz is not downclocked at all. you've only limited single core performance.
Remember it's 3.8 ghz base clock. Anything above is overclock. Either by design or manual. AMD does this pretty well out-of-the-box where the CPU overclocks itself pretty far without you doing anything.

The clock speed you see is basically the complete cpu package clockspeed. Those normally run at 4.x ghz. Each core has a different clock speed which you see in Ryzen master and HWMonitor.

Dump Core Temp. That one is the furthest away of the actuals speed and frequencies. Don't thrust that.

Re: AMD Ryzen 7 5800X High temps workaround.

Not sure what's your definition of downclock but from 4,8ghz I limited to 4,5ghz. Regardless, the issue is that is stuck at that frequency. It doesn't go any lower.

Re: AMD Ryzen 7 5800X High temps workaround.

A downclock is going below spec. 3.8 ghz is spec base clock.
A downclock can also be defined as going below the normally reached clockspeed under comparable load. Which is different per application because of boostclocks and the way they work

But none of that matters. Fact of the matter is you told the processor to run at 4.5 ghz. Any form of setting that clock speed would result in always running that clock speed. It's not a downclock because its a very normal allcore boost clock for this processor

Thats the issue with overclocking. You could overclock the 5800x so that it does an allcore clock speed to 4.7 ghz. Which is more then the normally reached ~4.53 ghz. But your single core performance would drop since it cannot reach the 4.85 ghz it would be able to do on single core.

AMD has a feature where it could apply different overclocking methods based on the situation but for that you would need to do some investigating yourself.

My advise. Don't do overclocking using Ryzen Master. But rather through the BIOS directly. You should be able to set the max boost clock using a multiplier. That should give you your desired result as long as the multiplier is lower then 45. Try 42 for starters. But you will hurt single core performance.

Re: AMD Ryzen 7 5800X High temps workaround.

According to AMD, unlike all previou cpus (intel or AMD) 5000 series cpus were design to reach the Tj Max (90~95C), that it's perfectly safe at those temperatures.

But if you feel uncomfortable with that I suggest you try undervolting in lieu of underclocking.  You can start with the negative off-set of 0.100v (-0.100v) to lower the temperature.

Re: AMD Ryzen 7 5800X High temps workaround.

For most games, the temperature is around 70 C, but when I tried to play Path of Exile, the temp jumped to even 90 C in some areas and the avg was around 80 C, which I dont think its a good think.

I dont know how to undervolt/underclock this thing properly, like I said, when I tried to undervol and underclock using the ryzen master app, it worked but the freq. was stuck at whatever I set it to, if I did 4,5ghz with 1,2V, the freq of the processor was never dropping from 4,5ghz, same if I did it by bios.

There is 1 thing I haven't tried yet, if only change the volt values in the bios, if I put a negative offset of like -0,100 / -0,200, then will the clock speed adjust acordingly to its voltage? Like, if with the negative off-set the maximum voltage than can be reached is around 1,2V then does the proccesor/bios automaticly calucates and adujst the maximum freq. and power consumption that it can reach according to the voltage?

@mrsense 

i agree with you that's intended and normal with poor cooling system like cheap air cooling with bad case airflow for example

Did you read the specs I have? All my vents are Noctuas, I replaced the air case vents with noctuas and the CPU cooler its NH-U12A, literarily the best on the market, there is nothing cheap on my cooling.
In fact, having my vents running at 100% or at 30-50%, makes little to no difference, only 1-2 C degrees difference. The AVG temp is around 70 C in games.
