Hi All i'm having A Problem with installing RAM if i try to put more than two sticks in my PC wont boot when i turn it on it will make a really load sound FAN sound on i think the board and the graphics card is where it comes from with the FAN sound.
I Currently Have TWO 4 GB Corsair Vengeance LPX DDR4 3000MHz sticks installed on my PC I Also have a crucial 4GB DDR4 2400 MHz And A QUMOX 4GB DDR4 2133 MHz now if I tried too install all 3 or 4 ram sticks my PC wont boot And also if i try to leave it on it will repeat with the loud sound noise from Fans then restart after about 20 seconds and repeat its self i have tried to install them in all different slots but with no luck at first i thought it was a compatibility problem, So I Ordered Two More Corsair Vengeance 4GB 3000 MHz DDR4 sticks and tried to add them but once again same problem and all 4 sticks are exactly the same but if i try Too Install Any More Than Two At A Time in any order it wont BOOT so if anyone could help me with this problem i would be so grateful!!!!

You have to set all the RAM at the same clock speed, same timings and same voltage. Usually, this will be the slowest of them all, so 2133mhz at 1.2v and set them all to the lowest CAS timings of the 3 types. Keep the Corsair 2x4Gb in the main dual channel slots of A2 and B2. This should fix it (make sure BIOS is updated to latest version).
