I just proceeded to the new installation of z97 gaming 7 motherboard. i am building this machine from a-z. i installed the psu, the cpu fans, and a i7-4770k.. So i found that when i moved 1 stick of ram to dimm slot 4, it works and boots up. however, if i add a second, paired stick to slow 2, the same "26" code appears and the same is true if i have all four sticks in..
