Hi guys!
Because ASROCK H81 PRO BTC are no longer available in my country I bought MSI B250 krait gaming MOBO instead. It has 6 PCIe slots so I thought it will be ok.

After installing everything as usually (windows 10 pro) I started to put all 6 GPU’s (sapphire nitro+ RX480 4GB) into mobo. But after launching I see only 4 GPU in device manager. I disabled on board Audio and Display.
Also trying Gen1 and Gen2 pcie settings and change PCIe risers for those I tested and I am sure they are fine.
I also checked this on different drivers but always the same result.
I found this in manual:
"The PCI_E2/ PCI_E5 slot will be unavailable when an expansion card has been installed in the PCI_E3/ PCI_E6 slot."
Is that means this mobo can only support 4 cards? So why it has 6 PCIe slots?
Can someone help me with that?
