Update the drivers to the newest ones.
I've already mentioned that I tried all the drivers from last year upto the latest one sep 2020 release. Same Isuue.
Uninstall Claymore driver that is used for straps and rxboost perform DDU and install the newest drivers.
See the above screenshot, even the Nicehash disabled the Claymore due to the DAG issue with epoch more than 379. It's a confirmed issue with Claymore. So unless the developer updated it, claymore miner is dead for ETH.
