For my brand new PC I have a 4x2 (8 gigs) ram kit. It’s a Corsair vengeance plz at 3000 MHz. My mother board is the msi pro vdh B350m. When I plug my ram into the 1st and the 4th slots(as give. In the build video I saw) the BIOS came up but showed only 4096 mb(4 gigs) of ram. Can you guys help me out?
