Question My PC works with 1 RAM stick but crashes when 2 RAM sticks are inserted


Jan 28, 2019
Mobo: Asrock B450M-HDV R4.0
CPU: Ryzen 5 2600
RAM: 2x8GB XLR8 PNY 3200Mhz
GPU: Asus GTX 1660 Super
PSU: Segotep AP550W 80+ PSU

I tried out both RAM individually and it works fine, memtest results show that they are working fine individually. The problem lies when I use the two RAM together (It's a dual RAM slot MoBo), they system boots and it just crashes, no BSOD or anything of sorts. The system just turns off without any warning.

This doesn't happen when I use only one stick of RAM. I also tried changing the RAM speeds to 2133Mhz when in single channel and in dual channel, but nothing seems to work at all.

My best bet is the power supply because everything else is working just fine (though it doesn't make any whining noises of sorts or anything related to being faulty).

If anyone has any sorts of idea please do let me know, I have tried basically everything.
