Hello! I plug 2 module Kingston HyperX T1 KHX1600C9D3T1K2/8G to ASUS P8Z77-V LX in blue or black slots DIMM, but it not starting. DRAM LED light. When I touch MemOK! button DRAM LED blinking and motherboard try starting correct long time, but not starting. When I plug one module DDR3 it`s OK. With two module DDR3 system start correct when I plug in DIMM_A1 and DIMM_A2 only. I flashing last BIOS, try setting manualy SPD memory timings in BIOS, set low memory clock, but it not help.(
In what may be problem?
Thanks!
