RAM Not Working

[MrBurns22]

hi i have recently just built a new system but am using my old memory sticks i have checked to see if they are the same DDR and they are as the board is DDR4 and the old sticks are DDR4 when i put a different stick of ram in the same slot the RAM is detected but i know that the other stick is working

Ram compatibility has improved greatly over the years but there still are cases in which a given stick just won't work on a specific mobo. Could be this is your case.

Well i tested the RAM on another Motherboard that is the same make and model as my mate has the same one and it worked on that one

Does he have the same BIOS revision? Updating BIOS might fix this.
