Hi . i installed MSI Z170A GAMING PRO CARBON 7GPU following this topic and personal knowledge, i upgraded that Mobo to this custom BIOS and tried also latest formal update 1.7 ..
Now the problem
i have 2 RX 480, Sapphire Radeon NITRO+ Rx 480 8GB GDDR5 and ASUS ROG STRIX Radeon Rx 480 8GB OC..
now i have strange issue .. when i install only one card ( any of these cards ) every thing work fine , card detected , get 28-29 hash rate .. but when i install both cards in ( PCIe-1 and PCIe-2 ) ,, one card have full speed GPU memory/Core speed 1200/220 speed and the other one get always stuck GPU memory/Core speed 300/300 always the ASUS..
see attached pix
any one ever faced that issue ?
do i have to install all 6 cards to make this work ?
and why always i get GPU memory/Core speed 300M ?
also Claymore miner didnot detected except one GPU ( the faster one only ) , it didnot detected the 300M card.
i installed so many AMD drivers 16+ . NOT 17+
changed risers
changed power molex
changed GPU setting in the bios
Windows 10 Pro UEFI
CoreI3 7Gen.... 4 G RAM

I got it to work .. was a driver issue and also the correct order of installing the cards . i will add more cards later to test the 7 GPU
