I have 2 team elite 4gb rams running at 2400mhz auto and recently i got hold of 2 corsair vengeance lpx 2400's; when i included the corsairs in my unit (Asus B150 ProGaming, i7 7700) all 4 rams ran at the speed of 2133. Done a checking and the corsairs are running 2133 auto and the other rams are synced with 2133. Why is this, when the team elites are running 2400 auto? I tried to enable xmp but found out that xmp is not supported on the team elites and i got a blue screen, so, i disabled it and all rams are now running at 2133. Question: why are the corsairs not running 2400 mhz on auto when their speed indicated is 2400? thank you in advance...
