Afraid I'm not sure I understand your comment
If not risers then what? or are you saying that the ones I have is the prbolem
Powering 1 riser with 1 sata connection I thought was according to the guidelines?
Equihash? Thats like #9 on profitability if you check them all
So with crashing your profits are zero.
Switching is a waste of money and causes crashing more often.
Once you get system stable you can add a few coins to benchmark.
No riser should use sata powered systems.
give me a link to your riser

these are better they use 6 pin pcie
