Hi all I have asus maximus iv extreme motherboard Intel core i7 3770K Corsair dominator gt 1866mhz ram The problem is that the cpu ratio can't go over 35 and when increase the ram freq to 1866 system won't boot .... The board never behaved like this before but the last time I tried to overclock was a year ago.. Tried clear cmos ... Update bios ..... Downgrade bios ..... Nothing worked Any idea about it ??
