R7 5800x on X470 Pro + Noctua D15 Temps

[The_Geek]

So finally got a good deal on a 5800X and replaced the 2700x on my x470.

It was fun and absofreakinglutely terrifying changing the CPU on the x470, although I had already updated the bios.

Hats off to AMD for up/down compatibility.

 

My only concern was the temps, this is what I have on HWInfo64, I have not OC's anything yet.

What do you guys think?

[Chris Pratt]

Are you max temps there actually max? Did you run an all-core load for a while?

[The_Geek]

I did a Cinebench R23 test and ran it for 10 mins. The MT Score was 15250, ST Score was 1523, the 100% CPU usage for 10 mins was at 4.45GHz, the MAX temp was 87 C on all cores

I think its pbo

 

Try setting the highest all core overclock you can with a voltage of 1.25v vcore leaving everything else auto, then check what your temps are

[The_Geek]

pbo? meaning?

[freeagent]

Its a little warm, but that is a warm CPU from what I understand. PBO is just the auto overclock feature. I prefer PBOII in the back section.

[The_Geek]

I have been reading up on and watching some YT clips on undervolting, but I am not confident on trying anything, as I do not fully understand it yet. A lot of the YT video's go very indepth and with all the mumbo-jumbo, the actual thing goes beyond my understanding(Thick head), so if anyone here knows what exactly to do on 5800x on ASUS  x470 Pro,  guide me please.

I have heard about PBO/PBO2 and all that, but till I understand it, I may not do it, or if someone has the same setup, and did the undervolting, give me the steps and I can try to copy it and see if it makes a difference.

[Mark Kaine]

well your temps are fine for cinebench…

 

 

do you plan to have your cpu running at 100% for a prolonged time often?

 

 

because if you dont thats of absolutely no concern.

 

but if you do, then 10 minutes  is far too short, you need to test it for many hours to see what the actual max is under these circumstances.

as already has been suggested, if youre concerned about temps turn pbo off, it will boost less agressive, and temps will be quite a bit lower.

Switching to 5900X, I got a great deal for it.

5900X runs cooler as it is, so I am sure the temps would not be an issue(Hopefully)

Plus I get 4 more Cores.. Lets see what happens.

The 5900X will be in my hands this week, I will post once it is installed and tested.

Thanks for the comments. I can always depend on this Tech community.

Awesome man, 5900X is an absolute beast

[Gohardgrandpa]

Can't you use the ctr software? That overclock a and undervolts the CPU for you 

[The_Geek]

So, I got the 5900X yesterday, (4 Days Early !!! YAY !!!)

It is a huge difference in temps.

Noctua D15 Air Cooler

Stock 5800X: Idle: 45-55 C, Cinebench23 10 Min Run: 87

Stock 5900X: Idle: 31- 34 C, Cinebench23  10 Min Run: 63

I OC's the 5900X to 4.2 GHz, I will run the tests again today.

CB Score: MT: 20458; ST 1593

 

What a difference !!

It was not just the UV and OC, I was more worried about the temps, I know UV was supposed to help with the temps, but I was not confident.

wait, you 'OC' to 4.2ghz? By default, all core load, it already runs higher than that by several hundred mhz. Typo?

[freeagent]

Probably all core. Not many people have cooling setups that can handle these properly it seems.

base clock is 3.7 Ghz for 5900X

I did a moderate 500 MHz OC, the system is stable, the RAM is running @ 3.2 GHz

DO not need it to go any further. I am happy for now with this setup.

And the Cooling is great, Noctua D15 is doing a good job.

[freeagent]

Your cooling is fine, but the CPU can do so much more on its own. Under the heaviest of loads (Linpack Xtreme) mine will do 4500 all by itself, that is the heaviest load that I know of. It runs faster for everything else.

5900x still runs higher on all core load.

5900x on stock settings should do 4.3-4.5ghz on all core load. so if you OC to 4.2ghz you are downcloking the cpu.

I have raised the base clock from 3.7 to 4.2, the 4.3-4.5 you are talking about is the boost and it is not on all cores, and it is short lived, only spiking when there is a load, I think.

But you do raise a point, I did not get a chance to check what the CPU was boosting up to after the OC, I will check it today.

boost and it is not on all cores,

there is max boost which is for single core. on all core load the cores will be between the base and the  max boost depending on the temperatures.

 

now when i cheked reviews for the 5900x it seems like it runs between 4.3 and 4.5ghz on all reviewers.

 

 

in theory if the cooling is really good all the cpu cores can get up to 4.8ghz on all core load (cooling has to be similar to liquid nitrogen) at stock settings

 

 

[SavageNeo]

the base clock is the minimum frequenzy the cpu runs on all core load NOT the frequenzy it will run.

I'll look into this.

yeah, I don't think you understand how the clock speed works on these processors. As others have said. By doing what you did, you have crippled performance. Anyway if that's your goal, no worries. take care. 

[freeagent]

No OC on my CPU,  stock clock range.. -30 set in curve optimizer and then PBO was disabled. I am missing a few MHz though, I am guessing because its warm in here, ac is not on.

New CPU, Old Cooler, although it is a great one.

I am just taking it slow.

the 4.2 OC is temporary, till I am confident about the temperatures.

Once it has been about a month, ans I am satisfied, I will be OCing the hell out of this CPU...
