i have 2 rigs, 1 with 2x290 and the other on with 1x290
i wanted to merge them to 1 rig so i moved the 290 for the second rig to the 1x slot in the first rig with a powered riser cable.
its a ASUS vanguard B85, with 2xpcie and 1pciex1. its a pretty new motherboard.
i plugged the molex to the riser cable,2 gpu are recognized perfectly(the 2 of the x16 slots) the 3rd gpu seems to work because on older rigs when the gpu wasnt recognized the fan would be at 100% speed.
here its on the case its like the other 2 that are working. and even more when i change the fan speed on Afterburner in Windows 8.1, the fan speed of the 3rd card changes aswell!
tried, changing the cables, all the gpus are working fine i tried switching.
i updated bios, set speed to Gen1, the thing with the fan really makes me think it should work. i have a decent PSU btw
any help appreciated, thank you
