I have Ryzen 7 3700x, asus rog strix x470f motherboard, and corsair h115i pro rgb 280mm aio and my cpu idle max 60c with lowest 33c.
this is true although it doesn't explain why many of us here including myself are experiencing issues when on stock settings with pbo disabled and why many people including myself are not able to reach the rated boost speeds and are somehow operating at a much higher temperature than those seen in the reviews. The current limits are only there to limit the entire package or entire package minus SOC.
This is not a case of people leaving PBO on and at motherboard limits as I have verified the exact same behaviour with the cpu at stock settings (confirmed by ryzen master showing "OC Mode" As "Default" on launch without any further configuration required meaning the bios settings are forcing "stock" behaviour.
There is something wrong with the boosting behaviour of this CPU. You can confirm this easily yourself by going for a manual OC. If I can get the same frequency at a much lower temperature it will clearly show that there is something wrong with the boosting algorithm right?
Well.... the proof is right here:

Notice how My system is pulling far less current here? Goes back to what I mentioned earlier.
Also just to re-confirm. I am running a custom EK loop with 2x 360mm Rads. Yup... custom watercooling and I have issues too.
Here is proof I don't get the rated boost speeds on stock: https://imgur.com/8J9Yrqa
Notice how my single core load temps are extremely high as well?
Here is how my system sits after just 5 mins of gaming: https://imgur.com/L8e1ytL
(Still haven't hit anywhere close to 4.9GHz boost on effective clocks) Click here for Full size img: https://i.imgur.com/L8e1ytL.jpg
Remember my PBO results from earlier? well compare them against this video: https://youtu.be/EtrCJn6Fr3o?t=693
(Should be linked to the R20 run he does, settings are at the beginning of the video) and my Bios settings are very similar to his, he also only has 1x 360mm rad keep in mind.
And there we are.. all the proof we need that something is not right with these CPUs on some motherboards. Keep in mind that some people have swapped mobos and seen a dramatic improvement. There was also a user here that swapped CPUs with a friend and his 5950x with "problems" was fine on another mobo and his friends 5950x which was "fine" experienced the same issues we are all having here on his mobo.
I understand people will instantly say, oh you have bios settings wrong and I would normally agree. However after spending hours upon hours trying to solve this myself and confirming I still experience this on stock behaviour with PBO disabled and don't even get the rated speeds I can confirm this is not a case of incorrect settings but a case of incorrect boosting behaviour experienced in certain conditions. The common factor here seems to be ASUS motherboards.
Again we need to somehow alert AMD / ASUS of this.
There is no issue with the installation, the IHS I can't confirm but surely very highly unlikely given so many of use have raised this issue, the boost behaviours are at fault and the common link is ASUS motherbaords. you can find countless threads all over the internet. Mostly all with ASUS motherboards. There are people in this very thread @Ero_Sennin for example who have mostly resolved their issues by moving away from an ASUS motherboard. When on manual I have clearly demonstrated there is a massive 30% change in current draw from manual to boost settings.
Why does the CPU not pull 200A in manual?
(1.2v 140A results in stable 4.4GHz all core (by this I mean I can run day to day and not run into any issues), why even with a negative curve offset does the cpu pull 200A at 1.34v when using PBO? That is 168W vs 268W a whole 100W of power extra is drawn to achieve the same clock speeds by the boosting algorithm, this is massive.) This is in my eyes obviously nothing to do with the mount or the IHS.
Why am I able to find people quite easily getting great results on every mobo other than ASUS?
Surely it can't be this much of a coincidence. There are 4 threads on this forum I've found so far, at least 1 I've found on ASUS' forum and pages upon pages of people raising their concern on various forums if you type "5950x Temperature" into google wherever the motherboard is stated its usually ASUS.
According to this I have an mid-entry level cooler. Not a full custom loop from EK. if this is the case I could have saved myself quite a lot of money.
What Mobo do you have and what temps and frequencies are you experiencing under a single / multi core load on R20?
Disregard this, I can see you have specified this while I was writing the reply
I have had mine since Nov 2020 also I purchased on release day.
I have also found something else in the past. This is what happens is I apply a -0.1v offset to the core:
Why is 1 of the CCDs acting different than the other, this is just a whole CPU voltage offset. This further confirms possible BIOS issues in my eyes.
I have been running 215/140/160 since you mentioned yesterday to see what the results are. unfortunately they are quite similar high temps although ever so slightly lower than previous and performance has taken a slight hit:
Single core I still don't reach 4.9GHz and temps are still ridiculous considering only a fraction of the cpu is being utilised and it still manages to reach the same temp as an all core load?
Ok so previous values were -12 on the best core per CCD -20 on the next best and -30 on all other cores.
Now I have -5 on Cores 1 and 7 on CCD0 / -10 on Cores 2 to 6 and 8 on CCD0 / -20 on all cores on CCD1 (9 to 16)
and the scaler on 1x as you suggested.
Still unfortunately seems roughly the same as the previous numbers.
all core:
Single core (somewhat better temps but still no 4.9GHz):
I've spotted something else odd.....
If the EDC is peak current and TDC is sustained current how is the EDC at 100% and TDC at 93-94% given the lower limit of 140 on TDC?
Hello
No change on that side, still running RAM at 3800 (in place of 4400) 18 18 18 45 - 1.4V with FCLK at 1900. Did not touch curve as yet since after few hours in use, all cores in CCD1 reach 5025MHz vs 4825 for CCD2.
Note that when gaming (BF5) , freq stay at 4600MHz for all cores with temp now always lower than 80° (only very brief jump to 85°C when in menus between levels...)
@ stock:
It just means the EDC is occasionally maxing out. The EDC shouldn't bottleneck performance during a sustained workload however. It is strange that TDC and PPT are not maxed, but your temps and voltage are within tolerance as well. Seems like the boosting is being cut off prematurely.
I added my run in below.
You can see my results are similar. My clock speeds are a bit higher likely due to the fact that I have +100 to the core under auto overclocking in UEFI. My temps are also a bit lower despite using the full 140A, but they are really that much different. Try turning on +100 under the precision boost overdrive settings with the 1X scalar. I am curious if you system will continue to limit itself in some way.
Now, your single core results are harder to explain. Again, I would enable the +100 and see if it will boost higher. Below are my results.
You observe much less power draw and current, with a higher voltage which is exactly what I see. What is strange is that your temps on single threaded are pretty high. You can see I am only 4C cooler than your setup in multicore, but 9C cooler is single with identical settings. Not sure what to make of that. Your cooler seems to be doing well enough under multicore, which specific block do you have again?
I also think you maybe didn't understand the odd behaviours I pointed out.
EDC is peak current
TDC is Sustained current
My benchmarks on all core will run with a constant 100% EDC and constant 93-94% TDC
So 100% of 160A = 160A
and 93% if 140A = 130A
So it's telling me the CPU is simultaneously pulling both 130A and 160A. There are no fluctuations
Similar to yours, it is telling you that you are pulling both 140A and160A at the same time, this makes no sense.
Also with your +100MHz recommendation:
all core:
Single core:
no change.
