Default RAM not recognised - faulty mobo or?

Win 7 64 pro, Asus Rampage III Extreme.

a total of 6 dimm slots (3 red, 3 black), one black is blocked by internal assembly.

Originally came with 3x 4gb sticks - was working as 12gb fine.

Recently i wanted to upgrade it a bit. MB supports a total of 24gb, so i got myself 2x 4gb sticks, to fill the remaining 2 open slots.
3 R were filled with original 4gb sticks, so i put my 2 new ones in the 2 open B spots. However, when PC booted up, the RAM remained at 12gb.

To test, i removed the original sticks, and placed new ones in their slots (1 and 2 red) - PC recognised 8gb fine.
When i placed the new sticks into 1 and 2 black, however, the PC refused to boot.

Which leads me to believe that for some reason the black slots on my MB are not working or are disabled.

Any way to check/fix this? Or does it mean broken motherboard?

Have you set the ram volts to normal? please refer to the manual for the proper placement of the memory in section 2.4 You'll need to download the manual in a .PDF format if you do not have the manual that came with your board
