Various Errors/Bluescreens with my RAM?

First of all thank you for taking your time reading this.

I wanted to upgrade my ram from 16GB to 32GB.

Old RAM: https://www.kingston.com/dataSheets/HX432C18FB2K2_16.pdf

New RAM: https://www.kingston.com/dataSheets/HX432C16FB3K2_16.pdf

Mainboard: https://rog.asus.com/de/Motherboards/ROG-Strix/ROG-STRIX-X470-F-GAMING-Model/

I knew that I had HyperX Fury RAM so I went on Amazon and bought an aditional 16GB.

When I arrived I saw that its not the exact same RAM and when I put it into my System it was kinda unstable.

After setting everything in the bios to automatic I managed to make it stable but it still didnt really worked. So I removed the new RAM and was a bit sad.

Later I decided to overclock my old RAM and managed to get it to 1.35V 3600MHZ 18-20-20-34.

Then I thought yea the XMP 1 of my new RAM is 3200MHZ 16-18-18-32 so I decided to put in my new and old RAM on 1.35V 3400MHZ 18-20-20-34 it worked out fine and booted into Windows without any problems.

I stress tested my RAM with AIDA64 and it made no problems after 30mins of testing.

But im still getting some errors (bluescreen + chrome crashes):

• Page fault in nonpage area system.service exception system thread exception not handled status access violation

(I have an error every 6h-2days and a bluescreen every 2-4days - mostly status access violation while watching youtube and then every 5mins-2h)

I also have the problem that my PC wont boot the first time in the morning. It just lights up and nothing happens - if I cut the power and start it again everything works again :/

I run memtest86 multiple times for multiple hours and it didnt find anything.

Now is my question am I stupid or is there any obvious problem I dont see?
