Careful with undervolts. It does reduce temps, but also may silently reduce performance because of clock stretching mechanism. Verify by running benchmarks before and after.
I think more reliable way to reduce temperatures is lowering PPT and EDC limits in PBO

Roger that. I did previously have a 0.1175 undervolt which is completely stable, but performance drops off.

At 0.0825, my Cinebench (granted that's not the complete 100% test) is the same, if not a little higher, but within the margin of error, as at stock voltage.

Yeah your stock temps seem to match mine, although I'm using a Corsair H150i pro AIO as opposed to a custom loop.

Now this is why I went for the Aorus in the end. I cant remember where but I read that the MSI is an incredible board hindered by a sloppy BIOS. I'm sure they'll sort it at some point.

Indeed, as soon as I touch anything voltage related, it locks my CPU to 3.4GHZ. This is on an MSI X570 Tomahawk MB

I have an MSI board, the 'cheap' one - X570-a PRO. I can't enable PBO for my 5950x at all without some really weird behaviour - if I run multithread workloads like Cinebench R23, one core at a time goes at full speed (swapping around which core every so often). Most of the rest sit at 547 or 574MHz, and system responsiveness in other processes grinds to a halt.

Like you, I'm waiting for a new stable BIOS release, preferably with an updated AGESA, before I try again at anything other than running at stock.
 
I am bloody LOVING the 5950X. Using it for video production paired with 3090s and it absolutely chews through 8K R3D raw footage, both full quality playback with final grades and effects applied and rendering. Rendering is at worst realtime, if not quicker, which is monumentally faster than our previous systems, and - touch wood - far more stable.
 
Was having some issues getting decent results using PBO on my 5950X with the Asrock Aqua motherboard.
Basically I found that I had to use the 'Manual' setting for PBO to set the PPT, EDC and TDC settings for it to boost correctly. I've seen buildzoid say to just set those to maximum but I found over the weekend that setting the EDC to it's maximum value was actually detrimental to my PBO boost performance. I noticed that regardless of what all core workload I was running it was always sitting at 230A. So I gradually reduced it and now having it sitting at 160A and the CPU is now boosting really nicely with lower temps. I was also able to set higher values in the curve optimiser. In the optimiser I actually do a per core negative offest, with the 4 'Best' cores specified by Ryzen Master having a lower offset value.
As I live in Australia where it gets really hot in summer using the PBO settings I actually cap the CPU at a maximum 85 degrees since leaving the temps unchecked can get a bit hairy when the ambient is 35c and above. This of course has the side effect of the performance dropping a little as my loop warms up, but it's still better than before. So my Cinebench R20 score on the first run using just PBO with an 85c cap was around 11300 for multi-core. Also noticed my CPU boost up to 5.15GHz during the single core test which was the highest I'd seen.
 
Complete novice here, but I'm wondering if people could give me some pointers on my 5950x.
Anything I should check to see if it's operating normally?

Do these temperatures look "normal" ?


Ignore the Maximums of 90....that was me testing fan profiles.



Anything else of note in these:


Like I said, dunno what I'm looking for :)
Thanks

Need a little more info like Stock air cooler/AIO/Custom loop ;)

Also need to put it under full load to see what the max is going to be, They do idle higher than what previous Ryzens do.
Mine on a custom loop in a room in the 18 - 19 deg range sits at 36 - 39 deg. On full chat 79 - 83

Thats with a loop temp of 35 as GPU is currently folding at 44 deg

VRM's look about right too
 
Sorry, yeah, it's a Arctic Liquid Freezer II 420, with 3x140mm fans on it.
Room temp about 20 degrees. I don't overclock anything.
Motherboard is an Asus X570 Crosshair VIII Hero

So, this is after 5 minutes of 100% load on 7ZIP benchmark:


It's normally in upper 60's after gaming, though gaming wise, it'll still be limited by my GTX 970 :D 6900 XT arriving tomorrow :)

Is there any way of displaying core clock speed and CPU temp whilst using MSI afterburner overlay?
Click to expand...

you need to have HWinfo open at the same time, go into HWinfo settings and enable the overlay for afterburner and select which sensors you want like cpu temp and clocks

After you enable the overlay, whenever you launch afterburner HWinfo will automatically start as well so it can feed sensor data into afterburner
 
So somehow I missed the info that on Zen 3, you shouldn't be using Ryzen power plans, and instead, AMD (specifically Robert Hallock) recommends you use Windows Balanced . So I tried that, and it's fixed the crazy spikes in temps you get even at idle.

Was worried it would affect performance, but running various benchmarks (Cinebench, Timespy and a few in-game benchmarks), performance is identical. It's helped with general temps as well, only by 1-2 degrees though

Yup, been saying this for a long time. https://www.overclockers.co.uk/forums/posts/34270791

Can also try setting it to Best Energy Savings for even lower idle temps.
