Hi, I need your help
I have a problem with rig, in fact when I plug my last GPU on my MB either my HiveOs doesn’t boot or
I see my last GPU (At the 6th position) like that →
It’s nearly always a comms issue. Kernel and drivers are fine for that GPU so, recheck and double check risers, adapters, cables, splitters, and power.
What does the rest of the rig look like?
Does your board have connections to power the PCI bus? Mine has 2x Molex ports for this requirement.
Absolutely. The board engineers put them there for a reason and the reason was enough to add to the cost of goods and lower profit margins. Power them up.
You can find a few other posts with the same situation and it was resolved with powering the molex ports.
fwiw: If your board also has a SATA power port, that is for the SATA peripherals. I do not use any of those and do not provide additional power to that bus.
