5950X & PBO

[AndrewPE28]

Maxing out my AM4 system and no longer worrying about gaming, I'm selling my 5900X3D and bought a 5950X. My primary use is PixInsight so multicore performance is priority. Just trying to maximise what I have and wanted to check if what I'm doing is sensible?

New Ryzen 5950X
Asus TUF Gaming X570 Plus - latest BIOS
2 x 32GB Corsair DDR4 3200
ARCTIC Liquid Freezer III Pro 420


I've set PBO to Manual, Scalar to 1x and Curve to negative 15.

Stock BIOS score in Cinebench R23 after 10mins was 22812 with max temps around 65C. Scores with PBO on are 26289 and max temps 87C. I'm an absolute noob to overclocking, I'm not interested in infinitely tweaking to get max performance, just a nice stable boost over stock. I tried googling the same CPU/MB combo and there isn't much info.

I built a 5950X system last year and eventually* turned PBO off. The gains (unlike AM5) were minimal for the massive increase in power consumption and heat. Couldn't justify it but YMMV.

*ran it for about a week doing nothing but benchmarks/stress tests as I built it for someone who lives a few hours away so gave it a bit of a kicking...

That's toasty 87c
I don't bother now but when I did
Overclock my 5950x
4.6ghz on all cores didn't get remotely
Near 87c
Though am using a custom loop

But if that's at the default 3.9ghz all core
Yeah its hot
There's a couple of good guides
For 5950x on YouTube
But the name of the channels escapes me
Right now

Edit
Skatterbencher
The graying tech
The second ones pretty simple
First ones got videos for mild
To extreme overclocking it

When i had my 5950x, undervolting (per core) and custom pbt settings first the mother board was the way to go. I could hit 30k on Cine bench with temps high 70s to low 80s

Hello, i'm just a n00b really, but after a bit of playing, I noticed that setting XMP on memory increased scores, but also increased power draw from mains socket (I use a power meter) by 20W across the board. Therefore I turned it off again, as i'm more interested in minimal power draw at idle: 65Wfor entire PC including monitor (whilst maximising performance when required). I realise this is a balancing act. Shame it cant turn on XMP when required....

My 5950x sits at 25C whilst idle, and hits 68C while Encoding/Prime95/Gaming.

I did set that undervolting thing to -30, but it didn't seem to make a great deal of difference. I'm, probably doing it wrong.
