2 sticks of RAM won't boot (2nd time because I accidentally selected a best answer even though my problem wasn't solved)

[Pen-guin]

Recently, I had to do replace my CPU and during the process, I removed a stick of ram so I could plug in components easier. Now, when there are 2 sticks of ram in the mobo the computer would be stuck in a boot cycle (No BIOS screen, just restart) but whenever I have 1 stick of ram the computer would work fine. I know that the ram sticks aren't corrupted because I tested both sticks individually and they both work. I also tried switching up the placement of my ram sticks (Instead of 1st slot and 3rd slot I would do 2nd slot and 4th slot) and again, only one stick of ram works. My best guess is that I need to change something in my BIOS.

I have:
Mobo: Gigabyte GA-Z170P-SLI
CPU: Intel 6600k
RAM: Ballistix sport DDR4 (2x8)

Try to Reset your BIOS using 1 RAM.
Install RAM either in Slot 1 & 3 & 2 or 4
