"Default Radeon WattMan settings have been restored due to unexpected system failure"
Hello reds,
Since Windows 10 Anniversary update came, I am having this warning when I upgrade my drivers;
I have 2 x AMD Radeon (TM) R7 370 Series 4 GB each.
Crossfire is ON in Radeon Crimson Software
Drivers up to date. Currently using latest 16.8.1 Hotfix. Does no matter with older drivers such as 16.7.2 Hotfix WHQL,16.7.1 Hotfix, 16.6.2 Hotfix WHQL, 16.6.1 Hotfix. or older.
Used AMD clean uninstall utility and retry but not worked.
Pluged off secondary monitor before reinstallation of drivers.
At Display Adapter Properties - Dedicated Video Memory shown as 4096 MB, before it was 8192 MB.
Even worst in games as it detects total graphics memory at 2048 MB such Rainbow Six Siege, Assassins Creed Syndicate.
I have tried another crossfire bridge cable.
All .net and Visual C++ are installed.
Furthermore, before 16.8.1 Hotfix released I was having driver errors and they were rolling back to 2015 drivers when the first error occurs. Now seems to be ok but no Crossfire. Know that Radeon Crimson detecs my secondary card, but AIDA64 sensors does not shows my secondary GPU sensors/diiodide, it only shows when I uninstall AMD Radeon Drivers.
GPU is currently unusable.
Waiting for your help..

You can turn off the notification in the Radeon Settings / Preferences. Yes they shouldn't be happening but that will at least stop them showing up. Wattman wasn't a feature in the 16.6.2 or 16.6.1 drivers or older drivers, but if you are using the new radeon settings with the old drivers that could be why you are still getting the message.
You can't go by what Windows says the video memory is as it gets confused particularly when it comes to Crossfire configs. As long as it shows correctly in the Radeon Settings there wouldn't be an issue.
Also when a GPU is in slave mode (ie Crossfire) then it is generally treated as one card as far as games and apps are concerned (there are exceptions)
