Give us more details. What is number of the driver version you are using currently? It could be that you are not using the optimal drivers for your gpus.
I am using same exact drivers for.I am running crimson relive edition beta compute driver for Windows 10 64 bit for rx580 hynix memory. Using same exact version on another rig without any probe. Same hynix rx580
Have you tried mining on single GPU only, a lot of reasons to be the culprit and needs to be addressed one by one.
Try to install single GPU on PCI-e 16x slot, in this way you would determine the PSU and Risers excluding them on the list when the problem is the same.
Then you may now have an idea on the remaining hardwares and softwares to be checked.
