Hi all, I bought a new memory stick after making sure it was exactly the same as the one I already have. They're both Corsaire LPX vengeance DDR4 8G 2400MHz; mobo is a MSI Tomahawk B350. But when I put the new RAM in the DMMB2 ( first one is in the DMMA2 ofc ) and boot the PC, it doesnt enter windows and freezes when the "press DEL to enter setup" screen appears. I tried to boot with only the new one only and it worked. I then tried to boot with only the old one and it worked. My suspect is this: I bought the old memory stick when I built this PC around two years ago, so maybe they changed something on the memory during this time ? Or am I doing something wrong ? Any help is appreciated. Thanks
