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?
More about7950 crossfire width
Fixed it by myself, new crossfire bridge, regestry edits, disabled the CCC overdrive Boost, Disabled UPLS, so yer done
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 .
