Hi to everybody.
I bought a Radeon RX Vega 64 8 GB and yesterday I tried to install on mining rig. I must point out that until yesterday 3 RX 580 Sapphire Nitro and 1 Nvidia 1660 TI cards were installed. I removed all the cards and tried to install the VEGA 64, but the system does not see it.

Motherboard is B250 Mining Board BTC 12GPU

Where I was wrong? What do I have to do to make the system to see the card?

Thanks a lot

Check in another working PC that you might have,if it works there normally it should also work in the B250 which for me personally is one of the best mining motherboards out there.Where did you bought the card?I don't think you bought it new as they are rare to find as new nowadays so most likely you bought it used,so as I said you should check in another PC you have available and if it works there then it is time to troubleshoot the issue in B250 board but you should try it in another PC as that is the first thing to do in such case.

If it works in the other PC,try to put first the card in the x16 slot and then try a 010S version riser.

The motherboard isn't a new one, but it works fine with 4 RX 580. Other PC, just like B250, haven't got any PCIe x16 slot, so I have to use riser. My risers aren't 010S version, but why do you advise this version?
Should I change any setting on motherboard BIOS?
thanks a lot

You must have a separate computer to test video cards. You don't need a PC but a motherboard, processor, memory and power supply. You can buy it very cheap on AM3 socket architecture.
If I buy a used video card, then I disassemble it, change the thermal paste and thermal pads as necessary, clean it from dust, test it and then install it in the mining farm.Even if you bought a video card with verification, it may be damaged during transportation.
