I'm back and Experimenting

I made this post a few months ago detailing how my 9800x3d died in my X870 Steel Legend Wifi mb. https://www.reddit.com/r/ASRock/comments/1lqt7a8/thought_i_was_in_the_clear/

I RMA'd and successfully have a new CPU and MB, both of the same exact model, so my build will be identical to when my CPU originally died.

The Experiment:

I plan to rebuild my PC either today or this weekend. I will first be flashbacking my MB to 3.40 before I install the CPU or anything else. Then, once the rest of the build is complete, the only BIOS settings I will touch are going to be enabling XMP/expo (I forget which ones my RAM is) and enabling PBO. I will NOT be touching any settings in PBO or XMP/expo, and the only other bios-related thing I'll do is set fan speeds. If the X3D CPU issues are fixed, then supposedly my PC shouldn't break again. If something does go wrong, I will be making another post, so assume that no news is good news.

Any feedback/recommendations are encouraged, and if anyone has any questions about anything, I'll do my best to answer in the comments.
