So I have been using the latest Claymore version since it came out.
My rig:
ASUZ Prime Z270-P
8x RX 580 8GB Nitro+ (Hynix)
Windows 10
Blockchain Beta Official Drivers
Claymore Dual Miner v.10.0
Modded BIOS, OC through Claymore @162w from the wall per card
Dual mining ETH (233 Mh/s) +DCR (7000 Mh/s)
Try to set original ROM, remove overclock and see if it helps, this way you can check that the reason is in your settings.
If your rig freezes, it must be something related to overclock, like wrong voltage for some power states, or something similar. It is not miner issue.
