Undervolt not holding 5800X3D temperatures

Hi, everyone! I'd be very grateful if you could give me any opinions on this subject.

Last week I upgraded most parts of my PC and ended up with this:

- Ryzen 7 5800X3D + DeepCool AK500
- Asus TUF Gaming RTX 3080 V2 OC 10 GB GDDR6X
- G.Skill Trident Z RGB 32 GB (2x16) DDR4 3200 MHz
- MSI MAG B550 Tomahawk
- Samsung 970 EVO Plus 1 TB
- Samsung 860 EVO 250 GB
- Seagate BarraCuda 2 TB
- Corsair TX750M
- NZXT H500 (with 2x Scythe Kaze Flex 140mm 1800RPM on the front and the same on top + 1x Scythe Kaze Flex 120mm 1500RPM on the back)
- BENQ XL2411P 1080p monitor (I know, I should get a QHD one but I can't afford it at the moment)

I'm not an overclock guy, so everything is at stock configuration, except for the undervolt I did on the 5800X3D.

After reading TONS of posts and recommendations, I ended up with an offset voltage of -0.1000v and MSI Kombo Strike set at 3, all perfectly stable.

The thing is: my temperatures got better, but not quite what I expected. Here's the HWMonitor data after playing about 3 hours of Chivalry 2 and CS:GO:

And here's the CPU on idle:

Strangely, I get better temps in RDR2 with everything on ultra, for example. That's why I'm providing info with Chivalry 2 and CS:GO. By the way, The Vanishing of Ethan Carter Redux with 200% supersampling makes the CPU go a tiny bit hotter than that.

I live in Brazil, so room temperature must be constantly around 28ºC. The dust filters are periodically cleaned. I reapplied the thermal paste to make sure that the CPU cooler was properly seated. Is it possible to get better temps without compromising performance?

Thank you so much in advance!

 

What's the paste?

As for 1080p - that may be for the best, since the card has 10GB of VRAM(sure, should be fine with games mentioned)... May not be as sharp as native, but I think things look pretty good if I downscale to 1080p.

 

The thermal paste is the Thermal Grizzly Kryonaut

Sorry, but I don't know if I understood what you meant by "may not be as sharp as native", because I actually play in a 1080p monitor. Were you referring to The Vanishing of Ethan Carter Redux?

 

The temperatures just look normal to me.

 

Could I tweak anything else (nothing big, like undervolting), so that they could reach low 70s or high 60s instead of bordering 80?

 

Idk, but those temperatures look fine to me (I also have this CPU) - if you were having 58 - 95 degrees under load, sure, but this is honestly fine. The same goes for idle. As for the undervolt, I've read that the offset method isn't recommended for this CPU. I followed the links below, just not through PBO Tuner, because my MOBO recently unlocked PBO tuning in the BIOS. It has worked for me as advertised, though maybe I also won the silicon lottery with my chip.

Undervolting the 5800X3D is a Must. Dropped up to 10°C in gaming, Got 1-2fps more with PBO2 Tuner at -30 : r/Amd (reddit.com)

Idle looks normal (I've also got the 5800X3D). Regarding HW Monitor, isn't left column current temp, middle column min temp and right column max temp? I would use HWiNFO instead since it has a fourth column with average temperatures.

 

I'm not exactly sure of what MSI Kombo Strike does. It seems to do something similar to Curve Optimizer. But I'm not sure.

You can try lowering other voltages. Like SoC, VDDP and VDDG. You might also be able to lower VDD18 a bit.But this won't do miracles.

probably the best thing you can do is to improve air flow in your case. Maybe add more fans.

 

Ive got a 5800x3d and yes those are the temps i would expect with that ambient and that cooler.
If you can, use an accurate method of monitoring the room ambient and the case ambient, both with have a direct effect on the CPU temps.
Having a case temp close to room ambient is an ideal target, your HSF and only use the air in the case to cool the component.

 

Higher native resolution should look sharper/better than downscaled.

 

Thanks for the info, emperorsfist! I've also read that about offset, but nothing very definitive. In my case it seems to be pretty stable and helped the temps. Regarding PBO2 Tuner, I think I'd rather wait for PBO to be better implemented in the B550 Tomahawk BIOS, cause I'm not hat comfortable with tweaking these things with softwares =/ It's really frustrating to have a B550 board and not being able to tweak PPT, TDC and EDC through BIOS.

The current and min. columns are like that because I took the screenshot after quitting the game I was playing. I thought the max. column was the only relevant one I'll see what HWiNFO shows.

Yes, Kombo Strike 3 is basically CO -30.

Are those parameters tweakable through BIOS? I'd have to follow some walkthrough.

I'm actually using all NZXT H500 available fan slots with good fans. The only thing I could do would be switching the stock DeepCool AK500 fan (a FK120) with a Noctua NF-A12x25. Do you think it would make a noticeable difference? These air coolers tend to come with good fans nowadays.

Thank you for the tips, mate!

I know, I just mentioned that game because 200% supersampling tends to be heavy on temperatures, which is what I'm interested in lowering

 

I wouldn't bother too much about max values as long as they're not sustained. Overwatch for example can sometimes briefly make the CPU load go up to 100% (thus momentarily increasing the temp) when starting the game but when playing the game, the CPU goes back to low usage and therefore low temps.

 

@Floydsound most people run -30 on PBO tuner no issues but you can set a separate value for each core. I have mine set to-30 and have it set as a boot time task in Event Manager.

 

Your motherboard didn't get a bios update with Curve optimizer?

 

I've got a Asrock Taichin570x, it's taken a long time for me to get the Bios just how i want, the voltages shown are not as applied so dialling it in has taken a while. For something I can do in software I'm not prepared to possibly compromise stability.

 

51c with 28c ambient is awesome! What's the problem ?

 

You can use bios from Verangry for MSI B550 and X570 https://www.overclock.net/threads/5800x3d-owners.1798046/post-29159784
