saamlott :
so, i have 3 TITAN X graphics cards but upon running msi afterburner stress test i found that only 1 of the 3 cards is actually working. it picks up the rest but only one is doing work (around 90%) and the other 2 are doing nothing(0-2%).
the more cards you add the less return on investment you will get
after two cards it really starts to fall off, as the vast majority of games only really support two at best
have you tried running a benchmark like 3dmark, valley, or superposition while keeping an eye on usage and temps with afterburner?
what are your complete specs?
