Hello, I've bought this motherboard especially for mining, I thought it was a good option but now I see it's a little hard to get it working fine... first I had problems detecting 4 gpus now I have 5 working after bios upgrade and some options on the bios --> All to Gen 1 and above 4G (cryptomining). So I'm still trying with 5 and it seems that the hashrate of one of the gpus (always the same position) keeps getting down and down like 15%-20% and stays there but that is not my main issue. I've figured out that of the 6 pci-e ports 4 x 1x and 2 x 16x, I can only use 5 out of the 6 pcie, exactly the one that isn't working is the grey x16, the one from above.
I also checked that it was not the risers nor the Gpus, and another little issue, after enabling the 4G bios option linux sometimes require 2 boots to start, one that shows bios and a quick flash of the SO colour and then keeps in grey/black screen and in the next boot, without any problems.
I thought maybe the PSU could be weak, but right now, I have 1 x 750w for 3 of these cards (580 about 150w off the wall) and 650w with 2 gpus, but my 650w can without any problem hold 3 of these cards so I'm pretty sure it's not psu problem.
Please help
