Hi folks!
Very informative post btw, thanks!
Just found it after looking for some info about the relatively high temps on my new 3700X, replacing my 1800X. For the time being, I am testing it on my X470 AORUS GAMING 7 WIFI (F42b bios) until I receive the ASUS ROG Crosshair VIII Impact for my planned Mini ITX build.
@rigg42 I would really appreciate your take on a few things as you seem to have a good understanding on how 3rd gen Ryzen works.
Starting off I just wanna give some facts.
According to Argus Monitor my idle temps are hovering anywhere between the high 30s up to 50C, usually around 45-51C with some really sudden fluctuations even with minor tasks. Temps under Cinebench 20 load are around 70-72 even when I OC'ed it to 4.3. I haven't run a full Intel Burn test to see what would happen under a sustained load for an hour.
(A small note here is that Ryzen Master usually shows me much lower temps at idle).
I am running the latest bios of my mobo, the latest chipset drivers, Ryzen's balanced power scheme, default bios settings (except XMP) and I have tried both my Noctua NH-U14S and my Be Quiet Dark Rock Pro 4 with the proper amount of thermal paste using the X method. The room is air-conditioned and has an ambient temp of 24-25C. Pretty much the same I used for my 1800X.
Coming from the 1800X (which idled STEADILY around 32-35C and a delided 8700K with similar temps in my other rig, these temps make me kind of uncomfortable. Yes, I read your post about electromigration, current draw and core count comparison and yes, I have also read a bunch of other posts pointing out that current bioses are still unnecessarily using high voltages on the auto setting but still wanted to ask. And yes, I did read AMD_Roberts's post about temp swings.
Should I just ignore this until the Bioses mature or is that just the nature of the beast?
Is my monitor tool giving me false readings? What do you use to monitor CPU temps in-tray?
Should I just switch to the Windows balanced plan? My mobo doesn't have a Normal option for Cpu voltage.
According to your very interesting post explaining how Ryzen 3000 operates, you write that when all cores are heavily loaded, vcore will go down to the low 1.3 range and will hover at around 0.9 in idle. It will only boost up to 1.4, 1.45 when doing small tasks. It's true, I noticed it in Ryzen Master. So why does the chip run so hot? From what I have noticed, C-States (if that it correct) seem to work fine.
On another note, I made some attempts to OC the chip, both through the bios and Ryzen Master. Although I managed to improve Cinebench results and get a
5172, I noticed that it made little to no difference when I benchmarked the CPU in a game like CIV6. Auto, 4.2 OC and 4.3 OC game me relatively similar results.
Am I understanding correctly that OC'ing has little to no benefit on this chip? Am I better off, just leaving settings on Auto and just try to optimize my ram and infinity fabric speed? I have a Samsung b-die 3200Mhz kit that I am trying to tweak using Dram Calculator and it seems to be responding well.
What works best for you guys for gaming? What is the optimal solution that maintains low temps? How do I know if I have a good chip or not? It was fairly easy to discern that with the previous tech.
Asking cause you wrote that setting manual Vcore with the multiplier on Auto kills performance. However,
here, I found a post of a guy having varied results in CB with different voltages (no multiplier set from what I understand). I don't know how these gains translate to RL applications though.
In any case, apologies for rambling on and writing such a long post, just wanted to get all the info sorted in my head now that I got my new chip.
Thanks again for all the info!
