plz help confused with different cards

[talboris2]

hi. i will try to make it simple

1) old motherboard with 1 Pcie and 3 small pcie
1 nvidia 1070 card and 2 rx570
using latest nvidia and Amd drivers.

when i connect  1 nvidia and 1 rx570 - on claymore everything good.

when i connect 1 nvidia and 2 rx570 ..something strange..the claymore very slow, and is says 2 or 1 gpu off..
and nothing is mining 0.00 M/h.. even though third card is working..

in claymore readmi its said that even mixed cards can work

now the SECOND problem.
 i disconnect nvidia and i cant turn on screen with Amd.
the screen is black - i use 1070 for screen
i cant even test Amd solo cards..
and again i used 1 nvidia and 1 amd and everything good
 
why even bios cant read amd? and with nvidia all works...

plz help.
thanx

I would remove all the drivers in safe mode using DDU. Then connect only the AMD cards and install the latest AMD drivers first. You then need to install the latest OpenCL runtime libraries from the AMD APP-SDK developer toolkit.

After all the AMD cards are detected and working, connect the Nvidia card and install the latest driver.

Also make the cards are not disabled with the -di parameter in the Claymore miner.
