Only 1 GPU Found

[Elixandre]

Hello everybody.

I have a problem with one of my new RIGs.

The motherboard is a Bfh B250 BTC Mining

That can be found here:

Bfh B250 BTC Mining Motherboard 12 PCI-E Support 12 Video Card LGA 1151 DDR4...

The processor is an I5 Skylake in socket 1151

Corsair 1000W power supply

I plugged in 2X6700XT but only 1 is recognized.

Regardless of the PCI port used, it recognizes only one of the two (it recognizes both but not at the same time) It is the same for other gpu tested (6800 XT / 6600)

I tried to modify the PCI speed (GEN 1/2/3), enable / disable 4G etc …

I have tried the solutions offered by HiveOS and on the forum for similar problems but nothing helps.

The risers and cables are OK and tested (because anyway the 2 cards are recognized by hiveos)

Does anyone have a little idea?

Check if the card works on some other PC, just to ensure if card is good. I had similar issue and found card is working on other PC. Issue was with bios. Check if you have latest bios and you are using stable AMD driver. Sometimes OS detect GPU but miner fails. Try changing miner to older but stable version.
