Need help. I’m having an error where miners can’t find the GPUs when 7th one is installed. All works fine as long as I only have 6 GPUs in any combination in any slots, but the error occurs once the 7th GPU is installed. I’ve tried various OC settings, even blanks. Max power consumption with 6 cards were 710W, so I know it’s not the PS. And I know it’s not the motherboard or the GPUs, because any combination of GPUs in any slots up to 6 works fine. The motherboard is BTC-T37, has 2core Celeron, 8 PCIe slots w/ 8GB RAM, 32GB USB stick, 1800W PS.
In NBMiner:
Device initialize failed
No GPU available for mining
In GMiner:
No device found
But in HiveOS, all GPUs are displayed:
