[SOLVED] My PC crash after new RAM installed

[StonedTurtle2]

So first of all,im from Hungary so maybe my English will be bad,but i try to write this question right.
So,i bought a new 8 GB RAM to my PC,and when i installed it,turn on the pc,go to play with AC Odyssey and after 10 minutes gaming, the game crashed. And the PC is doing it all the time right now. No matter what game i play,it just suddenly crash after about 10 min gameplay. (Overwatch,GTA V,Division 2,PUBG,Resident Evil 2 (Remastered) And sometimes the web browser do the crash too.
I bouth a new GPU with this RAM (RX 570 8GB MSI ARMOR) But i think the RAM will be the problem here.
PC Spec:
Motherboard:ASUS Prime B350 Plus
CPU: RYZEN 5 2600
GPU: RX 570 8GB MSI ARMOR (This is the new GPU)
RAM: Corsair Vengeance LPX 2400MHz DDR4 16GB (I bought another 8 so i have 16 now)
PSU:CoolerMaster Elite Power 600

I dont really know what can be the problem,so if u guys can help me i will appreciate it
(I doesnt want to buy new ram,or new motherboard or something,so i hope there will be a settings or something what will help me)
Thanks!

return the new 8GB stick, sell the old 8GB stick. then buy a 2x8GB ram KIT
