So a few Weeks ago I made my first custom built PC. I couldn't get it to boot with both RAM sticks so I'm trying to fix it now. I have tried enabling XMP and it doesn't help, and I have also updated my bios.

MOBO: Asus Z170 Pro Gaming Intel Z170 So.1151 Dual Channel DDR4 ATX Retail

RAM: 16GB G.Skill RipJaw's VKB black DDR4-3200 DIMM CL16 Dual Kit

Oh, and the cooler is blocking the first slot.

EDIT: When I turned on xmp only the ram slot I had ram in when I turned it on appears to be working, if I switch the ram to b1 or b2 the pc doesn't boot, however on default every slot that I have avalible (a2, b1 and b2) seem to work with a single ram stick.

Oh and both of them work alone, shouldn't have mentioned that before.

I am using an intel i5-6600k, so it is a K model.
