Hello everyone. I am having a hard time using all 4 banks on my motherboard. I originally purchased 2x4GB sticks of cruical Ballistix sport DDR3 1600 ram of 9-9-9-9-24 1.5V running on banks 1/3, and decided to add another 2x4GB of same ram to banks 2/4.

The computer will turn on with fans running but I have a no signal on the screen. I shut down and remove the two sticks and it starts right back up no problem. So I decided to remove my existing ram with the two new sticks to be sure they are working. I can confirm they work without a problem. I also tried switching the ram to banks 2/4 and it also boots up no problem.

Only when i try to occupy all banks will it not work. I even downclocked the memory to 1333mhz and added a slight bump in voltage with no luck. What could be the problem? All banks work but not when actual memory is using all banks.
 
Solution
Try with a pair in slots 1-3 and go to BIOS, set DRAM voltage to 1.56 and then set CPU/NB Voltgae to 1.25, save, exit, shutdown and then try adding the second pair
