So long story short, to make sure that my memory wasn't causing problems on my pc, i did a memtest with DOCP on (3200mhz) and it spitted out 12 errors in total. Once I turned DOCP off (2133mhz) no errors. What should I do? Thanks.

Try setting the DOCP profile BUT then change the Memory Frequency to 2933 and see what happen in Memtest86.

What EXACT Model % RAM kit do you have ?
Some LPX kits are suitable for AMD use, but Corsair doesn't really mark them specifically as such on the packaging.
There is some information on their website, but the key thing to look for, is a Z in the model name, such as CMK16GX4M2Z5000C18.
That means the kit should work with AMD. If you get a kit without the Z in the model name, it might not work.

Here are a few of the AMD Optimized "Z" kits I have seen:
CMK16GX4M2Z3200C16
CMK16GX4M2Z3466C16
CMK16GX4M2Z3600C14
CMK32GX4M2Z3600C18

If 2933 still gives errors try 2866 or even 2666.
That will let you know the fastest speed you can get with that kit with your MB/CPU.
Don't you think it's something with my CPU/MOBO I was getting failed post attempts, as well as system crashes and BSOD's...

Failed POST's and random crashes would lead me to believe it is RAM related.
And it has been proven that many Corsair Vengeance RAM kits do Not run properly with Ryzen builds.
we have seen a LOT of posts here about that RAM Not being able to run at the rated speed on Ryzen systems.
And the fact that you have a "Non-Z" kit just strengthens that belief.

Thank you for explaining all these info, just running the test right now. Thank you so so much. Do you advice me to try 3033 or 3133mhz or something like that?

No, try 2933, that is the next fastest speed most likely to work and if it doesn't try 2866.
And the real world difference between 3200 and 2933 or even 2866 is not really noticeable.
