I have a MSI 2A9C mobo, it rans 1333 ram, i have two sticks of 2 ram installed and one of 4 ram both ran at 1333, i also have a stick of 4 and a stick of 8 that rans on 1600, when i try to ran them they computer wont boot or when it does it will fail to lunch windows, it does recognize the ram in the bios with the 8 gigabyte stick but cant even load the bios on the 4 ram, is it possible to boot them on the system?
