I am not a hardware engineer, so this is a guess at best.
The design was meant to satisfy people that wanted the best of both worlds, a fast multi core cpu that has more than 8 cores, and can clock higher than the 7800x3d, and also people that want the best when it comes to gaming. So one...
Man, do y'all really run your monitors at full blast? Mine is at 20% or so most of the time. I have to use it for 8+ hours per day, anything over that and I start getting eye strain. (currently using 34" UW IPS) - To be on topic, I am keeping my eye on that 49", the price is not bad at all!
Maybe I am late.. for that kit to work correctly, I had to use EXPO II (which does sub timings too I believe?) then it would boot, otherwise I had similar issues. It could also be that your chip simply does not like 6000
I had a SL titan XL back in 2020 , it was $469 back them, in hindsight, not worth that much money, I thought it would be better than the generic gaming chairs, it is just a bigger version of those. I did not find it to be more comfortable or durable.
OOh, this guy had the same issues... but he said it's due to his CPU not winning the silicon lottery and the IMC can't cut it.

Well.. Noise.. not dumping heat into your case... having it actually fit easily and ease of installation too, those are a few reasons that AIOs are popular as well. Performance actually does improved over the better Air solutions (I actually run a FC140 on my 7900x, so I'm on air right now)...
