i have am3+ 970 chip motherboard with 16x and 4x pcie slots . i want to use hd 5450 at 4x slot for monitor display . and second r9 390x card at 16x slot for parallel computing (pencl). (without crossfire)
but if both cards are placed,display works only with 16x-r9-390x card as it is primary/default . but i want to use that card for computing and want display to work on 4x slot-hd5450 card .
in intel chipset they have option of changing init display first which is not available with AMD chipsets.
so how can change primary/default card from 16x slot card to 4x slot card in crimson or catalyst controll center ?
