Can´t mine with 3th GPU - MoBo Gigabyte GA-B75-DS3V

Hi guys!

I can mining with 2 GPS, but when I connect the 3th, my HiveOS identify the GPU model but not show the memory size (and not work):

My setup:

  • MoBo Gigabyte GA-B75-DS3V
  • 2gb RAM
  • Intel Celeron G530 2,4GHz
  • Flashdisc with HiveOS version 0.6-204
  • Kernel 5.4.0-hiveos #108
  • 600w PSU

I tried to:

  • Change all risers
  • Change PCI slot
  • Tried to conect just de 3th GPU (and show the same error/problem)

At bios I changed:

  • set to Gen2 at “miscellaneous settings”
  • Disable audio
  • At “Other PCI Device ROM Priority” I changed to LEGACY

There is not at my MoBo bios:

  • Above 4G decoding to enable
  • CMS Support do disable

I suspect that can be problem at GPU, what do you guy think?

Thanks a lot!
