Careful with this version, while people report no major power increase, if you ever watched the gpu power consumption in gpu-z, you will see that each card has a power spike when it finishes a share (or something in the same ballpark). If you take the avg power consumption, it might look ok for the PSU, but those spikes, if they are done at the same time on most or all GPUs, even a relatively good PSU will make the system freeze or even shutdown.
Just to confirm, there are some big PSU spikes happening.
Same here. I'm running 7 rx 480 on a single rig and had no problem with v.8. I've had to set -i 1 to stabilize the system. I'm using a Platinum EVGA psu, so its not that. Anyone have any insight?
