Hi everybody, I have a problem to need help

I have a rig with 5 cards: 1 x rx580.8g + 4x rx570.4g .
It has gone well in win10 64 with driver 20.4.2-may25.Hash : 32,2, 30.2, 30.2, 29.7, 29.3 => total 151.7 Mh/s

After I have uninstalled by ddu program the driver, I install driver 20.7.1-july9.
But the Claymore causes Windows system crashed. Is it not running with driver 20.7.1 ?
