I still get the "Cannot find Compute Drivers" when they are the only drivers loaded and have been DDU'd. 4 Vega 64 not seeing potential...

I am using the ASRock H110 Prod MB, the on board video is enabled, should it not be for this to work properly?

No I haven't tried that yet as they have been the only driver on this build and they were just functioning until early this AM when NH went down. But I've seen stranger things work.

The miner was a version of sgminer

I've scanned this topic but couldn't find an answer for this.

I have 4 Vega 64s that were running NiceHash Cryptonight at the 1900 H/s rate, but since trying to switch the Cast XMR, I keep getting the error about not finding the Compute Drivers.

Yes they are installed.

Any ideas or pointers would be very appreciated. Thanks!
