Ryzen 3950X Build Help

how did you get the 3950X already?
could this really be tied to binning? or maybe due to the chipset / features difference?

Linus is using 570X and his 3950X is more efficient than 3900X even, but is it binning maybe?

I seen the video,
3950X should be cooler (more efficient) than the 3900X-s
It should not be that hot :confused:

Comparing cooling results even with the same heatsink and cooler, is just an excersice in wasting time, IMO. Too many variables between systems to even worry.

Temps seem ok, so I say move on.

Hello All
Today I upgraded my Ryzen 7 2700 with a Ryzen 9 3950X - good news!
My Motherboard is an ASUS PRIME X470-PRO (BIOS Version 5220- the latest available)

Everything is fine but,
Why is the vcore get's up to 1.47V when I am not overclocking (not really planning to) but precision boost is on Auto (guessing it's means enabled)
And the core hits 56°C wathing Youtube and 47°C with ~no load, I run a stress test with CPU-z and got it to 89°C when the fan were blowing 100% @ 4,05GHz
So the cooler has contact with my
Thermalright ARO-M14O rated up to 240W

Can you please help me with this one?
Should I disable precision boost or this is normal /safe?
Maybe set the vcore manually to a safe value?

Edit - CPU-z validation:

Thank You!

PBO will pretty much give it as much voltage as it can if it's not hitting a power or temperature wall. Up to 1.5v. Thats actually pretty normal with other Zen 2 chips. As cores get loaded down more voltage might even go down, as if the current pull is too high the mobo just says no more watts for you. Best let it go... you can undervolt to avoid it but this is how they're made to run. You'll lose performance. To get to its boost it's gonna swing the voltage out... it seems especially boisterous on light loads, where there's no heat or power usage. It'll spike out to max voltage and frequency in bursts.

Definitely interesting to see your temps. My 3900x sits under a Dark Rock 4 and temps aren't quite that high. I'll see 38-50 for idle and any kind of browser usage. Anything past that goes into the 60's easily... though briefly. Heavily threaded stress tests will take it all the way up to 85. Gaming otoh stays 55-60. So bit of a mixed bag. The boosting behavior is just a bit different with these guys.

I will say... not even close to maxing the fans even when hitting 85c. Maybe 50-60%.

Also worth mentioning... we're talking early reviews. Could be bios/mobo variance. Mobos can greatly influence the little nuances of boosting behavior.

I mean... what's your case flow situation like? Only other thing I can think of. Other than the typical barriers to comparing cooling performance on different sets.

Honestly as long as you're not hitting throttling temps you're fine. And even then it's not gonna die on you. Just won't perform as well with more noise.

Not all on binning. Read the info or actually watch the benches. Did you actually watch or listen to Linus about the voltage and power draws? Don't wanna rewrite it all...

Ryzen 9 3950X reviews are live!

What freaking black magic is this!? binning ;p

Very nice, that is going to look pretty sweet with the corsair h115i and the Neo kit you grabbed.

For me the case is always the hardest choice...... Ended up with the Evolv X for my 3900X build but my wife preferred that over the 4-5 other cases I was considering making the choice slightly easier.

There is nothing wrong with the CPU. Dont disable anything.
You just used to different behaviour and different temp reading coming from the 2700X to 3000series. What you saw to 2700X was the average temp of the whole die. What you are seeing now with 3950X is the absolute hot spot of the cores inside the CPU. The 1000/2000 series dont report that.
Also the core voltage works differently in the 3000 line. When the load is low you will see high voltages but there is no stress to the CPU because the current is low. If the load increases and its more constant then the voltage drops to where is supposed to go.

You can see it if you install the HWiNFO64.

Can you please describe what it looks like with pbo disabled ?
tbh light load (browsing/video) looks pretty high to me though,mine usually stays at ~20-23W and tops at 30W.XTU shows my recent average at 16W core TDP and 20W package TDP.

Been looking into replacing my i7 with R5/7 but I spent extra on a passive psu and gpu,I don't wanna ruin that.

Zach_01 · Nov 19, 2019

Never tried it with PBO disabled. I may will at some point just for the info.
As for the consumption, I will say that you cannot directly compare 2 entire different CPUs. From different brands and from different time period.
Maybe what you see is more like the CPU+SoC Power (SVI2 TFN) reading... who really knows... That is closer to yours...
AMD with the last line disclosure some readings that in the past were hidden. Intel is still keeps them hidden IMO.

what cpu temp reding should I look at ? there are several.

Zach_01 · Nov 19, 2019

Im talking about the power consumption (watts) right?

I really doubt that your CPU tops at 30W unless I misunderstand something...

in browsing/videoplay ?
why not ?
and I don't even have speedstep enabled,it's running 3700mhz at 1.2v not downclocking

Ok get that... its normal. And I said that your reading looks like more close to my "CPU+SoC Power (SVI2 TFN)" ...about ~27W.
What I didnt understand is what are you asking by the...

"what cpu temp reding should I look at ? there are several."

there's several under CPU temp,one is edge and there's a few others.

Zach_01 · Nov 19, 2019

But we are talking about consumption/watts, I did not mention temp readings in our conversation...

I did cause you highlighted more than one :ohwell:

Zach_01 · Nov 19, 2019

I honestly do not understand what are you asking me to answer

I highlighted 2 temps... both true.
The Tctl/Tdie one is all new hot spot of cores (the reading is switching between different sensors in miliseconds to report always the hotest)
The CCD Tdie is either from a single sensor at some edge of the die/CCD... or it is the average of all 60+ sensors inside the CCD (I'm guessing the first)

Wow, great description mate,
Thanks for the insight, then I won't worry, and just get a liquid cooler solution - maybe

I run pbo off on my 3900x. 6 of 12 cores boost over 4600 while the other 6 stay under 4400. With PBO off, standard power plan (not 1usmus) I get a 7311 in Cinabench 20. I haven't compared to other 3900x. Pm me if you want any other info.

That seems a little low for R20 given the level of boost.

TPU review was 7224 and techradar was 7150 something. So it is at least on par. I haven't gone to 1.0.0.4b agesa either.
