as long as your lanes are set, 7x 480 is no different then 7x anything. supply proper power, use powered usb risers ( 12v for winners ) , and your rig will fly. decent ram, ssd, 1840g. mine on. it works, we have many. 480s, 470s, 390s, 290s, 280s, 7 works fine with all, same mobo exactly. works with 8 as well.
How can you make it work with 8 cards ?   I assume he did not try the RX cards |

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

I'm setting up this rig. Same motherboard, with Sapphire 480 Nitro 8gb cards. Cannot get past 4. I did use drivers mentioned above, then tried again with very latest divers. 4 work fine whilst installing one at a time, (working from slot 1 up), then on the second x16 slot...nothing. Then the 6th slot..nothing.
Has anyone else progressed from this in windows 10?

I had successfully run 7x RX480 8GB on Z97 Gaming 5. I use older driver like 16.9.2 or tried 16.11.x. Set at bios, 8x4x4x, Gen 1.
Extra thing I did was using Window Testing mode on by below step:
Open Command Prompt , enter bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS and press Enter. Then enter bcdedit.exe -set TESTSIGNING ON and press Enter.
Hope this help.

that's interesting, never done the testing mode, I shall try that tonight. I have tried the older driver before I tried then new driver, I was only getting 18Mhs on 4 cards. the latest driver runs at 25Mhs on 4. |

Just noticed the 2 missing cards are hidden in device manager, so I enabled one and after some rebooting and messing around, I now have 5. So one to go. It did not work with the 6th, now stuck in a loop of repairing windows so something has gone wrong.
Might end up re-installing windows and installing gpu;s from 7th slot down one at a time with an older driver.

I have tried the older driver before I tried then new driver, I was only getting 18Mhs on 4 cards. the latest driver runs at 25Mhs on 4. Tried the bcdedit.exe thing and it could not be opened 'access denied'. Not sure what to do with that. Next thing I tried was removing all cards, booting on 6th PCI-E slot first. Then reboot and connect each one counting down. Every time I came accros a x16 slot, I had to move the HDMI cable to that. When I got to PCI-E slot 1, windows simply does not boot up. I remove that card and boom. 24.5Mh/s x 5. I shall continue... |

WooHoo...done it. Using a combination of different help and common sense...Thanks klak for the note you put up they helped.
I cleared the driver using AMD clean tool
Rebooted
Installed 16.12 on one card...the 6th slot, not 7th from cpu
then shutdown, instal next, restart.
Last time I did this it did not work but this time I waited a long time before shutting down (5-10mins) especially the last card...that took ages, looked like the screen had frozen with nothing on the desktop. but I walked away and made a cup of tea, when I came back...the 6th had arrived.
fired up miner and it cut out (had this before too). I think it was too much power for my 1200w supply. So I turned everything off in the bias and device manager that I did not need. watched the power intake and it runs at 1080 W...
So now to work on getting that power down a bit, but at least I havve 147Mh/s
Think I'll run it at that speed for a few days.
OH, also put the PSU fan on permanent in case it was somethinng that got hot too quick in there.
Thanks all and I hope my experience helps someone else.
Si
