Default Problem with Sapphire R9 390 Crossfire

Hello people

I recently bought myself a second Sapphire R9 390 Graphics card so i could Crossfire them and hopefully get some better performances,The problem is when i enable Crossfire my framerates dont go up(During gaming)instead they plummit to the ground reaching Framerates about 15~20.

I installed the right drivers motherboard is crossfire compatible.
Hardware should do the trick i checked everything, I just took out the second GPU and i got no problems at all with framerates.

The ONLY thing i could think of is my motherboards PCI E ports , cause i've read some forums saying they must be the same of 16x + 8x would be fine,
However mine is 2 x 16x with 1x 4x the speed , I dont know if that would be a problem , Some people say its a problem and others say its not , I just dont know what to do anymore hence this post.

MotherBoard : Gigabyte G1.Sniper B6 LGA 1150
Cpu: I5 4690K (not overclocked)
PSU Corsair CX850M

I you got a solution for me i'd love to hear it, Thanks in advance

Hmm which specific model are these cards?

Firstly, yea it's the slot. The second slot is gen 2 4x while the first slot is gen 3 16x. That second slot needs to at least be a gen 2 8x for it to actually do any good.
