so I have 2 HD4890's in crossfire. my evga p55 motherboard is retarded and has the pcie 2.0 X16 slots to far away for crossfire bridge. I ordered a longer one online today. but in the meantime there is a second pcie X16 slot that will allow the card to run in crossfire but it switches it over to pcie X4 now during benches and such it actually seems as though my gpu performance is less than just the 1 card! WTF?!?! also in this slot GPU-z does not show the vreg sensors whatoever so no voltage controll. why?? the card is running and is detected and crossfire is enabled. but the 2nd card just runs in X4 mode. this should not do this right?? if I put the card in the bottom 2.0 X16 slot it runs and dectects normally with vreg sensors and voltage controll but i cannot run crossfire due to the crossfire bridges being to short. I thought about soldring 2 bridges together until my new on comes but honestly i dont think that possible. annybody help please?? maybe shed some light as to why this is doing this??
