Memtest results change everytime, would love some insight

[Saschajk]

Hi i keep getting bsod different ones every time but to my understanding all memory or storage related, i ran memtest multiple time also checking all the slots on the moba individually. and it does pass but with all 4 it failes.

I'd love to know if this is likely the ram?

We have seen errors that only occur with 2 or 4 sticks, but don't occur with 1 stick, several times.

2 or more sticks results in the system running in dual or quad channel mode (interleaved memory access).
It also changes the electrical load & EMI environment.
Sometimes these small changes are enough to provoke an error if the RAM is marginal.
