you can try to enable compute mode in registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000
add dword32 -> "KMD_EnableInternalLargePage"=00000002
does this work for all gpu's?
You can find out easily. If it doesn't then do it for each GPU which can't go into Compute mode by removing all other GPU-s. Another simple way is to use the Blockchain driver as long as you don't have more than 8 GPU-s. I don't see any big improvement from the Adrenaline edition.
The Blockchain driver has the compute mode already activated. You just set the memory clock to 2000/2100 through MSI Afterburner and you are good to go.
