Interesting you achieved this with risers. Have you ever tried to see what kind of hashrate you get without risers on those cards?
I'd be curious to see how that's possible on a board with only one 16x slot..

Ya I meant with just one card to see how much he is losing on the risers. Because his hashrates are better than mine even if I use a single card, no risers so I am curious how high his numbers can actually get.
