So you got 6 x16-x1 risers? Have you tried x16-x16 riser if you got one? i got a gigabyte mb which recognized all 6 cards if two of them are installed directly to mb or using x16-x16 riser. A bug or feature, don't know.

Yep, using 6 x x16-x1 powered risers, the H81 BTC Pro MB only has on x16 on board and if i place a card directly in the slot then it covers one of the X1 slots. I don't have a x16 to x16 riser to test, but guess I'll order a couple to try. Just pissed, have 6 480's sitting around doing nothing and diff is shooting up daily!

That said, looked on Amazon for a x16 to x16 and they all have shit reviews, not a single one looks good, people saying it has shit contacts and a few fired the MB.

Any recommendations on a quality x16 to x16 riser?

Watch those 16x-16x. I just fried a vid card with one of those. Luckily it was a cheapo I used just to setup Windows. I suggest to do what I had to do with the Msi. load one card at a time. Rebooting between each card. Also what vid connection are you using For mine I had to connect a special monitor plug to it. Lookup on Amazon. They are from compulab "display emulator". Get the hdmi version and connect monitor to the dvi connection of same card or the card that is in the 16x slot. Those mobo will work with a 1x-16x in the 16x slot.

Thanks for all the feedback, the Gen 1 setting in Bios worked and I can get past post but with only 5 GPU's. After some testing, I think one of the 480's just does not like risers since it works fine in another PC on the X16 slot. Anyway, I installed Win10 and it sees the 5 cards, less the flaky one that does not like a riser. But now when I start claymore, the display driver crashes and thus crashes Claymore. Using AMD 16.7.2 driver and Claymore 6.2 BETA.

Anyone running the same versions of driver, claymore, BTC Pro MB and 480's?
