im not very into overclocking but in bios everytime i use xmp with 3200 mhz it uses 1,45 v instead of the
recommended 1,35 which is written in yellow and i dont know how to change these setting and if its even good to do that .
can anyone tell me what i have to do or should i put the old 2133 mht cl 14 in ?
