Core Frequencies for AMD 3900X

I was curious to see how the cores are performing on various 3900X cpu's from the users on overclock forum after reading the SLR article about binning.

(https://www.tomshardware.com/news/am...ing,40157.html)

The cool part is that on the 3900X you basically have 2 chip-lets, each having 6 cores. In my case, i can see that one of my chip-lets looks pretty solid with core 0 going as high as 4,550.2 GHz which is very close to the advertised max turbo speed of 4.6 GHz.
I also like the fact that AMD got Windows 10 to use the best core during certain processing.

Please use HWiNFO for the readings.




Interestingly, Ryzen Master reports Core 03 on CCD0 and Core 07 on CCD1 as my fastest cores.

What overclocking settings did you use in ryzen master? E.g. PBO, manual, etc?

Also what benchmark did you run to get these?

I managed an all core manual overclock of 4.3MHz in a well ventilated case. Only tested using real bench though. Haven't tried more as this was good enough.

My system:
- 3900x with all core [email protected] cooled by Noctua D15S
- 64GB @3200MHz CL14-17-17-17-30
- RTX 2060 @2100MHz core, 8000MHz VRAM
- x570 Asus tuf wifi

PBO enabled in the bios, thats it. The bottom is Amd Ryzen master, and the other is the frequencies in HWiNFO64.
The frequencies are over time, PBO works really well.

Do you mind posting your Ryzen Master settings?

My CPU settings in my BIOS are all set to auto right now, and I've been overclocking the CPU exclusively through Ryzen Master but on Manual.

I can do [email protected] all-core and it's stable (can pass IBT and render and stay under 80C), but I've settled on this:

Not sure what it is that you have settled on. Is that PBO?

What are your ryzen master /bios settings?

Core 7 is the fastest core of that CCD

Most of the CCD0 cores should be better than that, due to the fact that CCD0 is significantly better binned.
Your observed frequencies indicate that as well.
