So just built my PC,
I have 2x8gb of corsair Ram 2400mhz.
When running the ram in #1 and #3 or #2 and #4 and any other combos, It will boot past the bios then becomes stuck on windows, the loader doesnt spin.
I have tried one ram stick in all slots, works fine. Also did the same for the other does work fine.
Mobo: Msi X370 Carbon edition.
