I have a minerbox with an AX-B85M-ETH motherboard… (I believe it is manufactured by ShenZhen AngXun Tech).
Anyhow… problem is PCI-E slots 4 and 7 refuse to detect any cards. At first I thought this could be due to PCI Express port 4 sharing the m.Sata slot , however I have literally spent hours trying different configurations without success. I’ve tried disabling Sata controller, setting All PCI Port bus speeds correctly, removing the mSata card and booting from USB, upgrading hive versions, and countless other BIOS changes including DMI Bus speed , PCI-E buss sharing etc.
Does anyone have one of these boards? if so, have you managed to get these ports working? Thanks
