slot#1 @ 16x

slot#3 @ 8x

not x8, x8, x16 that might be expected and what diagram shows. It has been argued before, asked Asus, and they said it's like that.
IIRC.
don't get me wrong donmarkoni, but i doubt this is correct.

if slots 1 and 2 share 16 lanes and also slots 3 and 4 share 16 lanes there is no way that slot 1 and slot 2 might get 24 lanes in total! might be wrong, but so might be the guy at asus who told you this.

anyway, as most of us wont use 3 way or even 4 way its more or less a hypothetical discussion. but if somebody with three cards at hand is willing to test this for us i'm curious to see the results.

ps. still waiting for my cpu and ram, so cant test this myself right now. besides that, my old cards wont support 3 way sli, so i'm lost here anyway ...
