Why did I get this BSOD error while gaming and listening to a stream?

Welcome to SF :) .
You best bet is to remove those last added sticks and see if the issues persists.
If you are reluctant physically remove them you can at least test your RAM.

Testing the RAM:

Test and Diagnose RAM Issues with Memtest86+:

• RAM - Test with Memtest86+

   Tip

• Pay close attention to part 3 of the tutorial "If you have errors"
• Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

When done with the testing procedure take a picture and upload it here.

Let us know :) .

tested it with memtest for 7 hours after I installed it.

*Tested it 9 hours 50 minutes it did only 5 passes...

I Know it's time consuming , which is why I initially suggested to physically remove them and try it
in that configuration for a while.
