Just built my first rig. Kingston SSD 120GB Biostar TB85 1150 mobo 6x RX480 Sapphire Nitro 8GB graphics cards Deep in the mines frame with usb risers EVGA 1300W Gold PSU
So here is the deal. I had a legit version of Windows 7, upgraded for free to windows 10. Started from there with installation of drivers. No matter what I have tried, if I plug one of the risers into the big PCIEx16 slot, the system will not load, no POST message, no signal sent to the screen. If I plug in a card to the PCIEx16 slot while windows is on, it crashes.
I have tried switching to gen 1 and gen 2 on the mobo BIOS. Switching a card I know works to this PCIEx16 slot. Just running the PCIEx16 slot and not the smaller ones. Tried a few versions of AMD drivers.
For what its worth, all 5 of the cards will have their fans stop right before windows loads to the desktop, then they kick back on. Almost like the system won't load until the fans stop. Claymore dual is working fine with Decred and Eth, but I don't dare mess with OC'ing these things until the 6th card works.
I am powering the rx480's with cords direct from the power supply unit. The risers are being powered by cables that I also attached to the PSU. The only thing I could think is that I have only 1 AUX power cord plugged into the board, the second doesn't fit next to one of the PCI slots.
Please let me know hat else I can try to use my 6th card.
EDIT: Actually randomly after a reboot, only 4 are found now and the 4th is hashing at a measly 4 m/hs. Ugh
