Beeps 3 times but ram works

Hello, I recently bought new components for my pc and this isn't my first time building a pc, i know some stuff about PCs and when a PC beeps three times it would mean that there is a problem with the ram I put it in multiple slots and still no display with 3 beeps.
So I decided to go to my friend and take both of my rams and try it on his motherboard, we removed his ram and put 2 of my mine.
Everything worked, so I jus want to confirm that the problem here comes from the motherboard?
