I recently bought a new ram kit but my pc blue screens every now and then all the error codes lead to faulty ram but how do I know for sure? Some errors I remember and kernel missing and system failure

What is the motherboard and ram in question?
Are you trying to combine new with old, or is the new ram a replacement?

Run memtest86.
It boots from a usb stick and does not use windows.
You can download the free edition here:

If you can run a full pass with NO errors, your ram should be ok.

It looks like you are trying to overclock your ram to 3600.
I found this comment in a review:
The Ryzen 7 2700 supports up to DDR4-2933 memory, just like the 2700X. Just be aware that you'll only get those data rates with single-rank modules installed in a maximum of two slots. Even then, it takes a motherboard with six PCB layers to operate at 2933 MT/s stably.May 16, 2018

Run memtest86 at default ram speeds.

Possibly there is a motherboard bios update that helps with ram stability.

I’m confused because I bought 3600 ram and I have newest bios

Yes but that doesn't mean your hardware can run that adequately.
Re-run memtest at default RAM settings one module at a time and then see.
If you still get faults on one of the modules then, return the pack.
Ok and should I set xmp to 2933 because what is default? Also how many parts should I do cause error was in 3rd part and that took 2 and a half hours
