update: Its already working
Apparently, the 2nd gpu doesnt like it when the first gpu's bios is modded. SO I had to load the original bios then installed the 2nd GPU and worked like a charm!
Topic: Unable to detect driver after installing 2nd GPU (Read 339 times)
I got 1 4gb hynix RX570 which was runninng perfectly. win10x64. Drivers were set, OCed as well which raised the hashrate from 24+ to 27+.
After a day of testing, i decided to add a second identical card and after booting to windows, my video drivers switched back to a default windows video driver.
under computer managment, it says 1 card is working properly while the second has a yellow exclamation mark. I get error saying something lik it cant detect my card from the sapphire utility. I tried other steps but to no avail:
- restarted the machine
- uninstall/reinstall driver from device manager
- ran amd cleanup utility and reinstalled driver
Any ideas?

I assume this are stock bios so
take the first card which you know is good in slot 1 or 2 or 3
pull it out.
put the second card in that slot.
boot if it detects it good it means the card is not defective.
come back to us if the second card works or does not work in the good slot
Thanks for the response!
So, I tried to remove the first GPU and moved the 2nd GPU to its place and it is working fine. Device driver shows 1 working GPU. Dxdiag shows the correct driver. I suppose this mean, GPU2 is working properly.
I tried to install the original GPU back to the system, now on the 2nd slot and rebooted the PC.
After reboot I checked device manager and just like before, one GPU is working okay while the 2nd has the yellow exclamation. Running dxdiag shows the driver is recognized and can see 1 GPU device installed.
Any further idea?
