Setting up ASUS PRIME H270-PLUS motherboard for GPU mining

To make ASUS PRIME H270-PLUS motherboard work with 8 video cards the following BIOS options should be set:

  • Advanced\System Agent (SA) Configuration
    • Above 4G decoding [Disabled] -> [Enabled]
    • DMI/OPT Configuration\DMI Max Link Speed [Auto] -> [Gen1]
    • PEG Port Configuration\PCIEX16_1 Link Speed [Auto] -> [Gen1]
  • Advanced\PCH Configuration
    • PCI Express Configuration\PCIe Speed [Auto] -> [Gen1]
  • Advanced\APM Configuration
    • Restore AC Power Loss [Power Off]->[Last State]
  • Advanced\Onboard Devices Configuration
    • HD Audio Controller [Enabled]->[Disabled]
    • M.2_1 Configuration [Auto]->[PCIE]
    • M.2_2 Configuration [Auto]->[PCIE]

probably not all of these settings are strictly necessary, but at least I was able to connect 8 video cards GeoForce GTX 1060 with them:

that gives about 2300 Sol/sec:

Also I found some specification of ASUS PRIME H270-PLUS describing its front panel connectors:
