I am getting the same issue as everyone here. Every rig is fine except one 6 GPU rig with a few 290s.

It hangs and you cant close the program , need to reboot.


I think the issue is that with regular mining, the GPU used little bandwidth to communicate with the CPU so the cheap ribbon or usb risers were fine.

But now with huge 100-200MB/s bandwidth going thru the ribbons which probably have interference with the surroundings is causing problems.

I dont think 100Sol/s or higher will be possible with any risers. Nicehash is releasing a new Nvidia miner capable of 50-60Sol/s and they are having issues with the risers also.

ITs also the reason why some of us get "gpu get incorrect data" because its sent back to the CPU and the ribbon messes up the data and you get incorrect sahres.

Try running with -i 0
