Hi like my title say i have those memory and board combine and gskills claim to be one of the best overclocking ram nowadays but i got an problem here . When i choose xmp my ram is automatically set to 2400mhz trying to change frequency and timing with higher frequency just dont work at all . I could manage to get it work to it 3200mhz though but i have to go manual and set cas latency to auto . I hear people talking about 3666mhz , 3866mhz and 4133mhz and those frequency are on the formula ix box too i want to know how can i overclock those frequency by using xmp profile . The manuel setting never work higher than 3200mhz . If someone could help with that i will really appreciate
