So I sent my B450-F MB to ASUS for warranty RMA because I got the yellow DRAM issue. Got an email back saying the warranty is void because of customer induced damage? WTF? So I look at the pic they sent me and it showing a scratch on a mounting hole. So their service tech probably damaged my motherboard and they want to stick me with the bill? I will never buy another ASUS product if they don't make this right!
