RAM not detected [SOLVED]

EDIT: I don't know why but when I turned my PC on this morning all 32 GB started to show up. Guess she issue fixed itself haha

 

Heyo,

 

so I bought a second kit of RAM, exact same model as the first, as an upgrade, everything is snug and secured in, OS should support 32 GB aswell, but it just won't show up in the BIOS. A1 and A2 work as usual, B1 and B2 are N/A

 

Specs: 

i7 6700k 

ASUS Z170 Pro Gaming AURA

4x 8 GB Corsair Vengeance DDR4 3000 MHz

ZOTAC GTX 1070 

500 GB Samsung 860 EVO

Windows 7 Professional 

 

Where do I start trouble shooting except for checking if the RAM actually sits properly in the motherboard? 'Cause that's all I can think of doing.

Does the bios detect them if you only have the new kit installed?
