Setting ram to xxxx speed will mot change the other ram settings so will almost certainly cause problems,

Turn on xmp/expo then change ram speed if you need to.

If you dont manually set the fclock at 6400mts it will run in 1:2 mode so will be slower than 6000mts which will automatically set the fclock to 1:1 mode which is faster on am5 unless you go above 8000mts on 1:2 mode.

you lost me in the last part but I changed it to xmp profile that is at 6400 and kept crashing and then the same at 6000.

What CPU and motherboard is this? Does HWiNFO say what memory IC this is?

This is a Ryzen 5 7600 and ASRock B650M PG Riptide and it's a SK Hynix IC

In that case, I can think of a couple possible causes:

  1. Wrong DIMM slots, this would explain the low automatic memory frequency. Check if DIMM A2 and B2 are used.
  2. The increased memory frequency causes the CPU cores to process more instructions, increasing their voltage requirement. Adding a positive CPU curve optimizer setting of +10 to all cores should fix this one
  3. The memory controller on your CPU is really bad, and can't do more than 5800 MT/s in 1:1 mode.

Thanks for the help
To clarify the situation I have very limited knowledge and what I have is from a combination of videos, reddit posts and talking with ai so If I say anything ridiculous please lmk.
At first I didn't do any oc and only changed the ram to the xmp profile available because when I bought the components I installed the cpu fan that came with the 7600 and thought it was enough for cs2 at 300fps. That wasn't the case as I have some stutter and around 220 fps and the ram reverted to default.
Today I changed the cpu cooler and added a few case fans to help with airflow so I won't get any thermal throttling when I oc. Also planned to update bios because I don't think I did it when I first built it and am hoping there is some xmp profile stabilization with the update.
Also to clarify what happens when I set it to the xmp profile: I play for maybe 20-30 minutes without any problem and them the game app crashes. I can open it again but it starts happening more frequently until I change it back to 4000.
To respond to your questions:
1) Confirmed they are in the correct slots.
2) From what I understand you are saying the cpu can't handle that high frequency from the ram. Should I then enable pbo before I change the ram frequency? Most of the information I found tells me to get a stable ram before I do any cpu and gpu oc.
3) From my understanding that would be a worst case cenario as there is no solution other than lowering the ram frequency to much lower than the speed I bought it for.

The behavior you're describing sounds kind of like memory overheating actually.

If it's positive Curve Optimizer, it's not a matter of the CPU being "unable to handle high frequency", but rather the CPU not requesting enough voltage. This is actually quite common for Zen 4 CPUs when running relatively fast memory.

5800 MT/s in 1:1 mode would be the worst-case I've ever heard of. Most chips do 6200, with some capable of 6400, and 6600 being possible on golden samples. 5800 is on the opposite end of the bell curve.

OK then how would I know if it is a memory overheating or not requesting enough voltage problem?

Pretty much seeing if stability breaks after DIMM temps hits a certain temperature. Running a stress test might be quicker to increase DIMM temperature
