I am currently using this setup:
I5 6600k
2x8gb hyperx fury ddr4
Cooler Master Hyper 212 Evo Heatsink
MSI Gaming Z170A mobo
550 w psu
r7 260x gpu

So basically I built my computer last night and put one stick of ram in dimm 2 and dimm .
when I turn on the computer the gpu seems to stutter and will not fully start spinning/turn on.

I tried all combos of ram ports. It wasnt until I tried dimm1 and dimm2 that the gpu was able to turn on and then the display followed.

So i'm only going to use 2 slots for my ram in the end and im curious can I get away with just using dimm 1 and dimm 2 or do i need to return my mobo,? (as there may be future problems)

Thanks in advance.
 
Solution
The RAMs do not work in dual channel and you might not be able to add more RAMs in the future, if needed. I'd fix the issue while board in warranty period.

How bad is it that I just dimm1 and dimm2 (as i will never be using dimm 3 or dimm4)
Do I need you use dimm2 and dimm4 like the manual says, or will i be okay.
