memtest passed.
cpu seems fine on stress test. (used prime95)
The difference with stock bios and modded one is huge. I need to get this working on this mb. I don't think motherboard is bad since it's working fine with gpu's default bios.
One more thing, GPU-Z doesn't show gpu or mem clock even with default bios. It was normal on old mobo.
Edit2: I got "display driver stopped responding and has recovered" error while mining with 1x rx 480 + 1x r9 390 (default fw). (This is the same error I'm getting with custom fw. after that miner restarts itself and I'm getting bsod)
1-flash back the original bios
2-remove amd driver , Display Driver Uninstaller : http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
3-reboot
4-install newest AMD driver with 1 card connected to your mobo : http://support.amd.com/en-us/download dont have to deal with patched atikmdag.sys anymore from driver 16.9.x
5-reboot
6-turn off the pc
7-connect another cards
8-turn on the pc
9-WAIT WAIT and wait a few minutes till win 10 assign the driver to another cards sometimes its take 5-10 minutes , Screen flickering is normal during this time
10-Dont reboot the pc till win 10 assigning drivers to new cards , if you do win 10 driver install going to fail , if you can open wattman without any error , all cards get the driver , then time to restart
12-dont change anything under wattman , get claymore miner , make sure you created the right bat file and let the rig run for a few hours
You missed a few important item from your "Here are some info about my setups" what VGA CARDS are U using exactly ( Brand , memory , reference card or not ) ? what modded bios u flashed to what card ? I hope u not flashed a reference card bios to a non reference card
