Ryzen 7 5800X Temperatures

[humbug]

Thanks for all the help.

I finally found the USB lead for my brothers AIO, but I'm completely out of thermal paste, so I've ordered myself some Grizzly which I should get next week.

I've got the case back together and the CPU at idle is bouncing between 35°C and 45°C

Now with curve optimising, do I wanna follow the guide I posted up at the top?

Precision Boost Overdrive --> Advanced
PBO Limits --> Disabled
Curve Optimizer --> All Cores
All Core Curve Optimizer Sign --> Negative
All Core Curve Optimize --> 20

Yes, the only think that i'm slightly confused about is "PBO Limits --> Disabled" you would think "Disabling" PBO limits would allow the CPU to draw too much power, tho i'm probably over thinking it and that's not at all what this means, i'll have a look at the video again later when i have the time, right now i'm going off line for a couple of hours.

For now try it. it looks about right

I've a 5800x and its been a hot little thing , not a golden sample, CTR gives it Silver.

I think the standard PPT EDC TDC is 142 140 95 or possibly 142 , 135 , 95 on the 5800x , regardless , it makes it run hot as hell.

If you make PBO limits manual you can have a play with them. I'm currently using 125 , 120 , 95 to try and keep temps under 80, but i've just changed CPU block so i might have a further fiddle with them.

I've also got curve optimizer at -5 for my 2 good cores and core 5 which seems to match them, -15 for the rest, anything lower i get random crashes.

I'm not boosting as high as i could , so need to mess about with PPT etc again which will bring the temps up. But looks more promising

I dont have a full breakdown of temps as i've messed around like crazy with PPT etc over the last month.

So anecdotally

Initial setup, with the 5800x in and PBO on ( fully watercooled ) with an older EK Supermacy Evo block, temps were over 80, .... 83+using cinebench, around 85-90 playing BFV at 1440 144hz for an hour or so.
Way too hot. Probably peed about with PPT etc and brought those down a bit, but dont remember how much.

Next i bought the der8auer ryzen offset bracket that moves the block off centre and also rotated the block 90% counter clockwise so the In was closer to the cores.
That worked on , temps 75-80 after an hours BFV.

Today just fitted a TechN AM4 block and its pretty damm good. Temps now 67-70 after an hour of BFV, temps 65-67 on Cinebench multi.

I've just put one in today and I'm not finding it too bad. Running Cinebench R23 on a loop for half an hour I got a peak temperature of 80.8 degrees (and a score of ~15400). That's using a Noctua NH-U12A and Thermal Grizzly Kryonaut on an MSI X570 Ace, and without doing anything except enable XMP. I know Cinebench isn't the roughest workload in the world, but after seeing reports of them hitting 90+ under any sort of all-core load it seems okay. Certainly can't compete with the 9800X I had on the raging inferno front anyway.

 

[heartburnron]

I found lowering PPT had the most immediate and significant effect on temps when I was using a lesser cooler than I currently have with my 5800X. Having this around 120 kept me closer to 80 than 90 when running Cinebench. Even though this reduced the maximum all core boost frequency by around 500 MHz, it allowed for better performance scores keeping the temp away from the 90 mark.

 

[DEL 707]

So I had another little play, here's everything at stock.



Then here's doing what I said earlier.

Precision Boost Overdrive --> Advanced
PBO Limits --> Disabled
Curve Optimizer --> All Cores
All Core Curve Optimizer Sign --> Negative
All Core Curve Optimize --> 20

So it improved my score, but no change with the temperatures.

Thanks everyone for sharing their settings and suggestions, but I need an idiots guide on how to do these things. I have no idea how to access and change the things your saying.

 

[humbug]

That's a more than 6% jump in performance, and 20% up from your original score. A score of 15452 is solid.

Yes your temps are still 90c but its not throttling anymore, good score, you're getting solid performance now and that is the main thing, the 90c temps, that just comes with the territory i'm afraid, tho its nothing to worry about the chip is designed to run like this, there is more you can do, you can cap the power consumption like @g67575 suggested but it might cost you a bit of performance.

See where is says "PBO Limits" Set that to manual, new options should appear, in it you will find PPT, it should be set at 142, set that at 120, or 110, or maybe even 100.

You should know that for most of us we are still getting temps of around 80c in high load applications like Cinebench, and we are quite happy with that.

Pretty madness for CPU Temp 90C and all cores at 90C with too much vcore at 1.41v (cpu could be degradation over time) Don't like it at all.

 

[humbug]

Pretty madness for CPU Temp 90C and all cores at 90C with too much vcore at 1.41v (cpu could be degradation over time) Don't like it at all.

Actually in a load like Cinebench the VCore is around 1.3v, the 1.41v is only in light loads where "within reason" it doesn't matter, it does this so it can boost higher in light loads, for example out of the box the 5800X runs at about 4.85Ghz all core in games at about 1.4v, gaming is a light load, in Cinebench it runs at about 4.6Ghz with around 1.3v.

The CPU is dynamic, its not an Intel CPU.

Please, you don't understand how these chips work, stay out of it, i'm trying to help this person and this isn't helping

 

[g67575]

Personally, I wouldn't be quite so concerned about benchmark scores. It's still a 5800X and is a very powerful CPU, more than capable of handling games and demanding software.

If you want a quick indicator of performance, run a moderate benchmark like CPUz and just check the multipliers for each core don't change much / at all (to keep the CPU speed consistent) while the benchmark is running, you can check this quite easily using a program like Speccy.

I don't know what options you have when you select PBO in the BIOS, if it's just enabled / disabled, just try turning it on and monitor power usage during a benchmark (with other settings at stock). Otherwise, just set it to a lower amount (such as 105w or 65w), until you reach a reasonable load temp.

If you lower the power limit of the CPU, it will just lower the CPU clock frequency slightly, across all cores, probably just by 100-200mhz.

 

[gerardfraser]

Op just got a hotter running AMD 5800X CPU . CPU Package power of 142w is normal.
OP can settle with an all core overclock of around 4500Mhz on low CPU voltage and he will not miss any performance at all and have lower temperatures while PC Gaming.
AMD 5800X is a fast CPU and just as fast as any Intel CPU. OP do not worry to much, just get the BIOS settings to where you are comfortable running the CPU.

If CPU voltage is too low you will get clock stretching's on the CPU. I know it is tough when you are looking for advice but take your time ,until you get what you want or return the AMD 5800X for another if not happy

Here is a normal half decent AMD 5800X chip with Cinebench set to 5100Mhz in Curve Optimizer.

Single thread 5100Mhz
Multi Thread 4750Mhz
CPU package power all cores -142w
CPU voltage all cores- 1.34v
Temperature- 76.1 ℃

Battlefield 5 AMD Curve Optimizer Set Up To 5000Mhz AVG CPU clocks seems to be around 4900Mhz and 68°C Max temperature

Thanks again for the help.

Here's 120W



and 110W



Looking much better temperature wise!

Slight drop in score when going down to 110W, is Cinebench consistant? Or is it down to the drop in wattage.

Either way, I'm much happier with the temperature.

Anything else I can try?

 

[humbug]

Cinebench is pretty consistent yes. the 200 points drop is due to your wattage cap.

Your scores are still very good, there isn't anything else you could do, other than trying for 100 Watts on the PPT but honestly at 80c in Cinebench your temperatures are just as good as mine now and there comes a point you have to settle with what you have, and what you have now is good. You did it

Thanks again for the help.

I can't find this on my bios setting B550 Asus Tuf Gaming Plus? I am using Ryzen 7 3700X base clock 3.6GHz and Turbo clock 4.4GHz but I locked at all cores ratio x40.25 and set vcore at 1.250v with all the rest on auto.

Cinebench running single core at 4GHz with temp never go over 47.5C, vcore at 1.248v and core 1 T1 effective clock @ 4.024.0MHz and core vids @ 1.100v with score of 1200pts with power watts of 41.856w.
Cinebench running multi cores at 4GHz with temp never go over 63.3C, vcore at 1.248v and cores effective clock @ 4.025.0MHz and core vids @ 1.063v with score of 12405pts with power watts of 91.292w.

If I put all default on auto with no locked at all cores and vcore on auto. I am scare if it running 4.4GHz with very high vcore and high temp. Should I look for Core VIDS not Vcore?

Ryzen 3000 is on PBO 1, its only Ryzen 5000 that has PBO 2, different architecture, i don't know how Ryzen 3000 PBO differs from PBO 2, i do know it doesn't have the Curve Optimiser but it should still have manual input options for EDC and PPT, i wouldn't know where they are in your BIOS but its shouldn't be that different from the video the OP posted in post #1

I did have a Ryzen 3600, i found the best way to run that was to leave everything but XMP as default, the CPU is very good at regulating its self, as long as your heavy load (like Cinebench) temperatures are no more than 80c for Ryzen 3000 you shouldn't worry about it and it looks like the way you have it set up your temperatures are more than fine, they are good.

You also should not worry about seeing voltages of 1.4 to 1.5v, as i explained to @bulldog147 this is completely normal, i know sometimes when people see this they get worried and there is a lot of noise out there about this being too high, i understand that, it does looking like its too high but it isn't, Ryzen 3000 and Ryzen 5000 have very sophisticated AI driven algorithms for Voltage and Current Regulation, the CPU knows exactly how many Amps and how many Volts the CPU can safely tolerate from literally one millisecond to the next, it is monitoring its self and making on the fly adjustments a thousand time a second, no exaggeration.

So, if you leave the CPU at default you'll get the best out of it.

 

[humbug]

Anyone who has a Ryzen 5000 series CPU, or a Ryzen 3000 CPU should watch this video, as well as going into what PBO and PBO 2 is he also explains how these CPU's regulate their own power.

And Curve Optimiser, what its actually doing.

 

[humbug]

I should really read whose asking questions, sorry @bulldog147 didn't realise it was you

I ran the 3600 for 2 years + and put some very high loads on it regularly, Unreal Engine light backing ecte... i sold it in perfect condition when i replaced it with the 5800X, it was rock solid through my ownership of it, never put a foot wrong.

Don't worry, the CPU knows what its doing

I am using Ryzen 7 3700X base clock 3.6GHz and Turbo clock 4.4GHz at default now. All left on Auto default with D.O.C.P enabled for 3600MHz memory at 18T, 22T, 22T, 42T, 83T, 630T, 1T (16GB Ram)

Why is Cinebench multi cores only run at cores effective clock @ 4.079.6MHz not 4.391.8MHz? Is that normal? I noticed there is RED on Power Reporting Deviation (Accuracy) 81.3% (Red) minimum and 107.9% (black) maximum - should I worry about this?

Yes its normal, the CPU will always push for the highest clocks it can, with in its default perimeters or perimeters that you set for it.

So for example, lets say the CPU is set to use up to 100 Amps, up to 80c up to 1.5v, the CPU will set its self to clock until it reaches any one of those given perimeters, in a high load like Cinebench it may reach 100 Amps at 1.3v at 4Ghz, so that is where it will cap its self, in a lighter load, like a game, or Youtube or Cinebench Single threaded the CPU may only pull 40 Amps, now because the Amps are not so high it can safely turn the volts up, now it can run at 1.45v and with that run at a higher frequency of 4.4Ghz.

This is how the CPU is dynamic, it doesn't run at a fixed frequency because its constantly monitoring its own perimeters and then making adjustments accordingly, 1000 times a second, once every millisecond.

 

[Grandmaster Fap!]

Hey guys, sorry to hijack the thread but can you not just undervolt the cpu to lower temps? I just got a 5800x myself coming from a 2700x, that was a hot chip but i just set volts to 1.35 and it boosted fine and never went above 60c. Is the 5800 different?

Thanks I am all new to AMD and still learning as I been using Intel i7 2700K for almost 12 years. Big change from Intel to AMD. Now a final question: Am I better off leave it all on auto and don't worry about up to 1.5vcore or am I better off with my fixed ratios x 40.25 and set vcore @1.250v? Cos the benchmark only slightly little difference
