I bought an CrossHair IV Extreme for my FX 8320E. I'm having doubts about the configuration in the bios, and i'm having some problems with my memory, my computer is booting just with clicking in MemOK button, i use 1866Mhz 1.5v memory. And any configuration in bios like disable C6 state, i have a overclocking error message. Can you help me?
