9800x3d temps

[Subtilizer]

i just checked with libre hardware monitor and behold CCD1 really IS in the 30's LoL.
thanks man!

I wonder why the temperature of the crystal itself is 50 degrees, instead of being equal to the temperature of the nuclei?

 

[RootinTootinPootin]

For that puny CPU?

yeah, I hate seeing idle temps around 40-50 which is around normal for you guys, I love seeing my idle temps to 24-26c and load temps around 48c for that chip (this is a dual D5 pump setup)..same with my 9950X3D, 2x480mm 60mm and 1x360mm with 4xD5 pumps..

I feel like its not overrated or overkill, some members here even have a Mo-Ra..lol..compared to mine, mine's a baby watercooling setup compared to those..lol..

because the cores itself are on another node (4nm) then the SoC is (i believe it is in 6nm). They are on separate chiplets. also the SoC is a complete different design, that produces totally different temp characteristics, than the actual cores.
If you want to reduce your idle temps, you must lower the SoC temp by disabling xmp or expo, running at default settings, also disabling the internal gpu helps lowering the temps.
but running your ram with the default 2400 mhz would gimp your performance a bit.

Icy cool temps by running with no expo type speeds..

SoC R7 9800X3D I have 1.205V, I don't think it's much. However, the temperature is high when idle.

Not a lot though, it's an X3D, it doesn't need fast RAM.

But I agree, I would only do it if temperature or idle power consumption was a massive concern (which it isn't in OP's case).

It needs something... maybe a new IO die. I'm not a huge fan of my 9800x3d - i've gotten it mostly smooth - but for a high end gaming CPU it's pretty stuttery. The framedrops hit like a truck.

My 9800x3 stay at 43C in idle, with 30C of room, I have noctua nh-d15 g2 lbc, and case corsair 5000D(6 fans), when I got the cpu 2 months ago, was 26C in room, and the cpu had 37C in idle, did some tests then, (cinebench, 3dmark, so on), the biggest number I got was 84C, so yes it is a hot cpu, and he will want to boost most of the time, if the temps allow it...this will be very good in winter, no need to heat the house, just play games...even the chipset of motherboard it is high(57C)...summer time.

yeah same here ccd1 shows 40's idle 33 room temp.

 

[Subtilizer]

I have this situation in idle. 50 degrees the crystal itself and 38-40 degrees the cores. Is this normal?

 

[abdulhkeem]

what's your room temp?
what you need to watch is ccd1 temps others are io die.
looks fine to me unless you are at lower room temp than mine.

Thank you. The temperature in the room is somewhere around 25-26 degrees.

hmm for me its very consistent, frametimes are very constant for me. try to disable gpu-power read out in afterburner and restart your pc.

"Only" have a 7800 X3D, but my situation is similar: Tctl around 50, Tdie around 35 on idle. Air cooled by NH-D15. Seems fine, as temps rarely exceed 70, only for short times when all cores are being used, i.e. for a shader compilation or a benchmark.

I have - it's consistent-ish - it's just not consistent compared to other platforms.

The games that stutter stutter really hard - like run around hogwarts in hogwarts legacy and watch your 1% lows tank into the 40's as it loads in assets - that was not a thing on my old build. So when you compare 110 FPS avg and 70fps 1% lows vs 150Fps avg and usually 90 fps 1% but then every 3-4 seconds a 30fps 1% -- you see right away what experience feels smoother.

I finished HL on my 7800X3D and never experienced such a thing.

the 7800X3D (apparently) doesn't do it - that's the wild thing. Look online of people who upgraded to 9800x3d they're complaining like crazy:

https://www.reddit.com/r/AMDHelp/comments/1in08ux/how_i_fixed_my_9800x3d_stuttering

From AMD7800X3D to 9800X3D, stutters!!!

Gained about 15% in fps, but it stutters quite a bit, the 7800X3D was very smooth, this 9800X3D is not. If I increase graphic settings it stutters the same as if I reduce them, so that does not help, sometimes I see CPU bound in yellow but sometimes in red, which I never saw with the 7800X3D, so ...

^ i tried all of these but still have a stutterier chip. Im on a different board now (the ASROCK B850M) and about to blow away windows and reinstall it (again) - all newest bios - but still; lots and lots of people having these issues with specifically the 9x3D chips. They're fine but meh.

This exchange pretty much sums it up:

It seems like a fragile platform on the 9xxx side of things
- rivatuner can cause stutters
- c states being off can cause stutters,
- PCIe contention can cause stutters,
- wrong powersettings,
- igpu being on,
- steam overlay
- bios defaults not defaulting
- mouse over 2khz
- keyboard plugged into wrong mobo usb....

what a diva of a chip.

How many of those people think they are pro tuners running unstable overclocks?

Probably most of them.

This is my experience at default settings and XMP as well.

If i didn't have another platform to compare to I would be super happy. But having had a smoother build in the past - the 9800x3d ain't it (for me).

You can see the delta in reviews as well... higher 0.1% lows and lower averages = smoother.

Higher average and sameish lows and lower .1% = stutters. Not all games, but enough of them.

Me neither.. I am sure its ok.. but I am bailing from the X3D boat

 

[Space Lynx]

Can't say I have had any any stutters at all with my 7800x3d 7900 xt build. I haven't finished many games this year, but I have dabbled with a lot of them. Metro series at 240 fps 240hz has been smooth as butter on a pancake

nom nom

I am dying as I wait for dinner ugh

I don't know if I would call the platform fragile on all 9000 CPUs.. my 9900X is an animal. It is no X3D but it still rips. Can hit 275w PPT with PBO lol

I've an 7800X3D if you wanna swap

what games stutter for you specifically? I want to download them and give it a try just for the heck of it.

 

[Frizz]

Currently idling at 42C on 9950x3d with a Mora IV 200 and direct die heavily tuned system though, used to idle 50ish... My 285K used to idle at 26C without direct die haha and had no microstutters whatsoever.

I have been shouting since I bought the 9800X3D and 9950X3D that it has a flaw, the stutters even show up on a Linus video where he was showcasing it while playing POE2 but they blamed the game lmao. I was thinking I didn't see that on my 285k ...
