Are the three cards on a separate PSU? If the answer is yes, you've got your bottleneck right there.
Iv got one 750W Gold on two Gtx Ti
Those 7 cards are connected to 4x 750W Gold PSU
Yes FOUR 750W power supplies for one rig, 3x 2x 1080Ti for one power supply and one 1080Ti + motherboard and cpu.
haha dafuq
You think 750W for 3x GTX should be enough ?
"blackoreo" i think you should go use nicehashminer : ) we can't help you
Ok, thanks for support.
