Don't use the "blockchain beta" driver. It is already included on the latest AMD adrenaline drivers from amd.com/drivers. Please stop spreading old news!
-> go to amd.com/drivers and download the latest WHQL driver
-> open the adrenaline control panel and change the settings from GRAPHICS to COMPUTE mode for EACH AMD CARD that you have. Reboot and recheck if compute mode is still enabled
You should have more speed than using old blockchain driver that was created for testing purposes. Also it's the only driver that is fully compatible with windows 1803
you sure? i did not test the last drivers for rx series
but i can say on vega the blockchain is at lease 5% faster than the adrenaline
