Hoping someone has an easier solution then reinstalling windows 10.

6 RX480 Rig (2 Asus, 4 Gigabyte), Windows 10 64, Claymore 9.8, Modded Bios, 100% stable dual mining Eth & Sia, 16.9.2 Drivers.

When I install any new drivers including the blockchain one just released (Not the shifty one) My cards take 16 seconds instead 4 to load the dag and all hash at 4 mhs instead of 28.3. Crossfire is off, ULPS is disabled. Had the same issue with the 17.2 drivers.

Have 20 Gb of space for Claymore, Windows doesn't update because I never activated it.

Here is the process I am using to install the new drivers.

Run DDU in safe mode (DDU restarts the computer), Install drivers, Restart, Run Pixel Patch, Restart, open Afterburner, Open Claymore 9.8.

Just reinstalled the 16.9.2 drivers and my rig is mining away at 169 Mhs. Did the exact same process as listed above.

Am I missing a step? Anything else to try? Do I need to just start over and reinstall windows?

Thanks for you help in advance
