Detailed description: Hello guys, is it possible to run 2400MHz without XMP? 

earlier this day i borrowed my girlfriend's laptop which is an ASUS A407UF running DDR4 4GB 2400T.

I borrowed it because i wanted to test my ram sticks (one of them is faulty i think, because it got 4.1GB system reserved) and it's a DDR4 4GB 2133 RAMs. 

so i tested it on my gf's laptop and both runs fine, but when i put back the 2400 RAM it reads at 2133 and i already checked BIOS there's no XMP settings. 

anyone have a clue on how to change the 2400 RAM from 2133 back to 2400 ?

sorry for my bad explanation and English .. Thanks
