I’m running 128gb on a 9550x now with 4x32gb sticks and it’s terrible. It’s unstsable, post time is about 2 minutes (not exaggerating)and I’m stuck at a lower speed. I’m considering just taking 2 of the sticks out and working with 64gb and increasing my swap partition. The nvme drive is fast at least.
This is my first time off intel and I have to say I don’t understand the hype.

The long POST times must mean it's retraining the memory each time, which is not normal. Just in case you haven'ttried it yet, I'd start by reseating them, I've had weird issues with marginally seated RAM before.
Also you definitely have to go much slower with 4 sticks compared to two, so lower speed as much as you can. If that doesn't help, I'd verify them in pairs.
If they work in pairs but not in quad at the slowest speed, something is surely wrong.
Once you get them working in quad, you can start bumping up the speed, might need voltage boost as well.
What ddr5 speed are you running? 6000 is technically an over clock, AMD only guarantees being able to run at something like 4800 or 5200.
You may need to bump up voltages slightly for your CPU's IMC (I needed to on my ryzen 8700F to run 6000 stable). Its CPU sample dependant.
Also as other commenter pointed out, typically 4 sticks will achieve lower stable clocks
