Hi guys,
I've mobo ASRock H110 Pro BTC+ with 8x GPUs 1080Ti to today. Today I bougth next 3 GPUs, connect them, but detected next ONE card only. Hash power decreace too. With 8 gpus I had about 6400 Sol/s, now have 5500 Sol/s... Sad

There are some limitations for GPUs count or any settings for nvOS?

See nvidia-smi:

Code:

and number of plugged GPUs in mobo:

Code:

m1@rig-bafomet:~$ sudo lspci | grep -i VGA | wc -l
11

Thanks for advice

There are NO such limitations; nvOC is designed to max of 13 cards without any modification of 1bash & 3main (can add more by modifying these two files). Try to verify the risers (swap them around with the working ones).

Hash rates dropped with your 8 cards??
