Hi, I just got a kit of Corsair Dominator Platinum DDR3 2400 16gb (4x4gb) and put it on a Asus Rampage 4 Extreme. Unfortunately when I choose the memory XMP to get it to 2400 Mhz the system wont boot. I had to reset the mobo and choose manually the memory's frequency to 2133 Mhz and the the system starts ok. The Bios is all as default. I even upgraded it to the last version and same story. Is there anything else I should modify on the mobo's bios in order to get the memory to 2400 Mhz?
