Did you connected power to the molex connector on the motherboard straight from the psu with nothing else on the cable ?

The same cable is used to power the riser, but the problem is that using the sigle GPU directly connected on PCIe x16 doesn't work !

I have no problem on PSU is 1200W and the problem occur using 2 or more GPUs

Then I dont know why with B85 Anniversary I didn't have this problem !

What can be the problem ?

Did you checked your PSU ? Try using another one . If you switched the motherboard already , and all those cards you have , have a same problem it can be a psu , but make sure that molex power connector is connected to the mobo.

In my setup (H97 Anniversary with RX480) i have onboard video enabled , and 6 RX 480 cards running just fine .

I have a couple H97's running 6 cards, but they were much more of a pain to get going than the H81. The biggest thing I found was you had to disable the onboard video, and use the card in the full-sized slot... Everything else went relatively smoothly after I figured that out.

All of mine are on risers (USB style) - so I would just confirm that you're giving them enough power via the molex connectors on the riser. I never tried mixing both riser and non-riser, but I doubt that would case an issue.

I have a H97 anniversary that runs fine with no card in the 16x slot, and PCIe video set as priority in the BIOS. I did have problems figuring out which 1x slot gets picked as primary when there is no card in the 16x slot; it doesn't seem to be consistent. If I have to hook a monitor up to the rig, the easiest thing is to stick a card in the 16x slot, and that always gets used as the primary video card.

How I can disable onboard video ?

on bios you can just specified pci express as primary video but you can't disable internal video

Hello,

I have build a RIG unsing H97 Anniversary MB with 1 RX480 and 3 RX470 RIG, fist of all I have update the bios of MB isert RX480 on X16 PCIe slot but I was never able to boot, I have try also with all other RX470 with the same result.
I have change the MB for a new one but I get the same problem, do you know why x16 PCIe slot doesnt work on RX cards ? There are some particula BIOS settings ?

Next step was boot the RIG using internal IGP and 1 RX480 GPU on x1 PCIe slot and riser card, this works and I was able to boot my Windows 10 OS and install the Radeon latest driver, so I start to insert the second GPU RX470 with riser and I get a driver crash and I was never be able to have this card working I have try to change all possible PCIe slot with same crash every time.

I have try also using linux Ubuntu, same problem on x16 PCIe slot that doesn't boot and same problem using 2 o more GPU the sistem crash.

What can be the problem ?

Maybe the riser card ?

I have use this riser with B85 Annuversary MB and HD7970 for some months with no problem !

Thanks

Fabrizio Huh
