I recently built a ryzen 2600 pc with 8gb viper 3000mhz ram in a MSI B450i gaming plus mobo. It worked when first put together and its what I've used till now. But I'm trying to install a 16gb kit of vengeance lpx 3000mhz and it won't post. I cleared out the bios before I started, I tried one stick in slot one, nothing, one stick in slot 2, nothing, alternated the sticks and repeated action, nothing. The cpu light will be the only one to come on, it stays on then tries to reboot. I swapped back in the old kit and it works again. I checked and MSI says the kit is supported. What could be the issue and why isn't it working?
