7950 Crossfire 32 bit bus width

Hey guys I have 2 7950s in crossfire and one is running at the normal bus and bandwidth of 384bit and 240GB/s
but the other card is running at 32bit bus width and 20GB/s Bandwitch:

here are my system specs:
i7 3770K Stock (currently)
Asrock Extreme 4 Z77
2x 7950 Powercolor PCS+
8GB of Cosair Vengeance
OZC Agility 3 120GB

Any Ideas on how to fix up that bus speed?

  1. Fixed it by myself, new crossfire bridge, regestry edits, disabled the CCC overdrive Boost, Disabled UPLS, so yer done
  2. Gpu set up look like this. 1x gpu=x16; 2x gpu=x16+x16=(x32); 3x gpu=x16+x8+x8=(x32); 4x gpu=x16+x8+x4+x4=(x32). so 2xgpu=4xgpu.
    If the slow gpu is in x4 port u only get 25% of the speed.
    insert both cards in x16 slot to get full speed .
