Hi,

I'm having a hard time mining with 6 GPU's on this board.

I have a Asrock B450 Pro4 motherboard on 4.8 BIOS.

CPU is Athlon 3000G.

Above 4G is on, CSM is off. I tried all PCIE Gen (1 2 3).

Integrated GPU is disabled.

Running HiveOS

Here is my problem:

If I put 3 cards using risers in slot PCIE 1 2 3 (X1 X16 X1) the 3 cards work.

If i put 4 cards using risers in slot PCID 1 3 5 6 (all X1's) the 4 cards work.

When I add a 5th card in a X16 slot, the rig take a lot more time to post, HiveOS struggle to boot, but when it finally boot, it detect the card and and gives me error that there is like no driver support.

If i put 6 cards, system don't post at all.

Anyone can help with this? Any BIOS setting that I am missing?

Thanks
