Problem with installation 2xRX570 Nitro, Sensors cant be read

[kulas9]

Hi all!
This is my first post here. I am kindly looking for your help. I am trying to build my rig but I met some problems. Here is what I've done,

I made fresh windows 10 installation, with two RX570 Nitro plugged into motherboard. Then I downloaded blockchain drivers and installed them. Here is the problem...
Both cards are seen by Windows. However, I wasnt able to flash any of my card because I get error in atiflash that it can't read roms. I figured out that one of my card doesnt work in standby because of ULPS settings - I disabled it. Atiflash now is showing me both cards, I am able to flash them. Names of cards are different, one is Radeon RX 570, the second one is ATI Radeon Polaris 10, why there are two differnt names, while cards are the same? 

Claymore can't read sensors of one GPU, which is frustraiting, cant undervolt, manage fanspeed etc..  Here is my screen showin problems in  Atiflash and claymore https://i.imgur.com/KcGDsJS.png

Are you running it headless or is the monitor cable plugged into the one showing as RX 570.

Which RAM type is the misbehaving one showing, Elpida?

I have monitor plugged in. Both cards have Samsung memory. It is strange behavior because separetly they work fine. I can undervolt them etc, but when I plug both, I have problem with one of them.
