the maximum temp on my CPU is around 80c with a few Cinebench multi-cores runs.
CPU: AMD RYZEN 5800X + Noctua NH-D15 + Thermal Grizzly Kryonaut
Graphic Card: EVGA GeForce RTX 3080 FTW3
MB: MSI X570 TOMAHAWK
Memory: G.Skill Flare X, 4x8G F4-3200C14D-16GFX
PSU: EVGA SuperNOVA 850 G3 80+ Gold
I mean I am glad you atleast included some parts that you are using unlike other people but case is also incredibly important.
Just too many variables when talking about temperatures.
Also it seems like DOCP is likely to be contributing to higher temperatures for sure. I can't enable it on mine on 126.96.36.199 and so my temps are quite a bit lower than when I was running 188.8.131.52
what sort of WHEA you're fighting with? whea 19 bus/interconnect warning one?I had the same issue: my 5800X would boost to 4525mhz, 1.32V and reach 85-86C in R20 under water!
I've switched to an all-core OC of 4.7ghz at 1.22V and my R20 temperatures have dropped over 10C to about ~72-73C under load. I'm still tuning, but give something like this a shot first. Ironically you may actually have good silicon as it's possible we have low leakage chips. That is, they will run HOT AF with generalized PBO settings that are better suited for average or high leakage chips, since a low leakage chip will run much hotter than a high leakage chip given the same voltage.
So yeah, my theory is that some of the ones that run very HOT out of the box are actually good quality silicon that just manually need their voltages reduced. Otherwise poor contact below or above the IHS and to be honest I just don't care enough to check/redo my thermal paste application.
Now I just need to figure out the WHEA errors piling up in HWiNFO64 (another somewhat widespread issue) with in my IF set to 1900. Lowering it helps, but I'm hoping that a voltage setting somewhere could resolve it.
well, some say that 200MHz steps are for Intel and AMD really likes 266 so it's 3200/3733 or 4000 I'm really stability freak other than anything else (my old Intel set had like 3 BSOD during it's whole lifetime ~5 years and all of them were caused by me) so I can live with 3733 and tight timings. I'd be harder if 4000 was an option, but this is yet to be determinedI get no errors at 1866, so I guess I'll just leave it at that. My OCD wants 1900, but I'll have to revisit that later. Maybe it's just not possible on my chip.
Cinebench is derivative of Maxon c4d 3d rendering...so any CPU-based 3d renderer (c4d native, VRAY, Arnold) would yield similar results. These renderers truly max out all threads.This happens only when running benchmarks such as Cinebench.
That's similar temps i get with a 5950x same cooler. I got PBO enabled. The 5800x is the same 8 core ccx silicon thats in the 5950x so it would make sense the temps be similarHi there,
So my 5800X on Asus TUF Gaming B550-Plus with Noctua NH-D15s, Fractal Define C (2 intake, 1 outtake)
In Cinebench 20 it gets to ~80C and stays there, give or take 2C depending on how fast I allow fans to run.
Real life is much lower ~65C +/- 5 depends on task.
I must say I'm pretty happy with it. Looks spectacular too!

Been fiddling.Yep, same thing here. I can run intensive single-core small FFT AVX benchmarks on my 5950X for hours and top out at 67C but browsing the web sometimes it hits 75C and the fans spin up loud as hell. And that's after weeks of WHEA black-screen reboots, finally fixed by running a beta BIOS. AMD definitely doesn't "just work". It's great hardware but the frameworks, AGESA, etc, are not ready for prime-time.
Honestly if I had it to do over I'd just get a 10850K. Ryzen is a huge pain in the ass.
yea, all in all with same PBO settings these processors take the same amount of power, just 5800X pushes it all to one CCX (I guess inferior silicon quality) while 5950X with better silcion distriubutes it to two CCXesThat's similar temps i get with a 5950x same cooler. I got PBO enabled. The 5800x is the same 8 core ccx silicon thats in the 5950x so it would make sense the temps be similar
If you hit 90C at stock settings, you have an issue with your cooling or case airflow.
The 5800X/5900X/5950X all use up to 142w by default. The higher core count CPUs clock lower in all-core workloads by default because that power is spread out over more cores. This is why pumping more juice via PBO is such a huge multicore performance gain on the 5900X and 5950X in particular. At stock my 5950X only clocked to 3.7Ghz all-core; with PBO unleashed it went up to 4.35Ghz. Your 5800X probably clocks much higher at stock settings.
