Help with Corecycler and undervolt guide – 7800X3d

Hi all,

Can somebody please help me to understand this undervolt guide for my 7800x3d.

My Experience/Guide to Undervolting the 7800X3D – Benchmarks, Temperatures, Stress Tests, and Common Questions/Concerns : r/Amd (reddit.com)

In the initial steps, @ Safe-Economics-3224 talks about using CoreCycler-v0.9.4.2 to do baseline testing.

He provides a config file for these tests. This config file uses Ycruncher, mode = 22-ZN4 ~ Kizuna and includes tests BKT, BBP, SFT, FFT, N32, N64, HNT, VST, C17.

• Repeat this process until you are able to pass CoreCycler overnight (i assume that is with the abovementioned config?_
• Lastly, run y-cruncher overnight with all tests enabled???

I can't find anywhere where I could enable all tests. It appears to me that the original config file IS all tests? (BKT, BBP, SFT, FFT, N32, N64, HNT, VST, C17.)

Looking at this image in his post https://preview.redd.it/my-experience-guide-to-undervolting-the-7800x3d-benchmarks-v0-k6rqp5gq8gqb1.png?width=905&format=png&auto=webp&s=95d13d2bef2b56a029efa7118b95f040f8d23345

It shows "8hr Corecycler HyperThread", then lasty "ycruncher all".

What have I missed here? As I understand, Corecycler is just the script that runs through each core individually? What is a Corecycler Hyperthread Test?
