Long time lurker first time poster.. today i added a riser to one of my rigs and tried to use my old r9 270 with my 2x rx 480 in same rig.. it detects the 2gb r9270 but it has 0 mhs.. some help please thanks. This is my first time using a riser so maybe i missed a step?
Raiser is nothing more than "extender", if system detects the GPU - all should be fine in terms of the hw connectivity
