Basically i have three sticks of ram, 2 sticks with 4GB 2133mhz 14-14-14-35-50 and 1 stick with 8GB 2666mhz 16-18-18-39-61. My high IQ idea is to match the 2133mhz timings and frequencies to the 2666mhz. So in the end it would be 3 sticks with 2666mhz 16-18-18-39-61 (16GB total). My voltage now is 1.2v, so i would put it in 1.35v. Does any of what i wrote here make sense? i really didn't want to change the 2666mhz timings because it's the better ram and i want it to live, but is it better to find a middle ground timings between the two types?
