Will my (2x4GB) Corsair XMS3 CMX8GX3M2A1333C9 RAM have compatibility issues with a 4gb stick Corsair XMS3 CMX16GX3M4A1333C9? Same model technically but slightly different? I'm not versed in these situations. Appreciate any help. Thank you.
Corsair does not guarantee such a combination to be compatible together. Since you can make any combinations you want, you can do your own compatibility testing with no guarantees.
