Resolved Issues with AMD Radeon Software Crimson Edition 15.11.1 Update
Better, but still some considerable way to go.
1) Some sort of crash with a filesystem error reported on first reboot after installation. Seems to be trying to run a web page??? (start ~~ "https://secure.amd.com/di?UID1=................" etc, etc,). As this does not happen again, it's cosmetic.
2) GPU clock on this 'ere 280X now switches between 300 at idle and 501 Mhz under load. While an improvement on "permanently locked to 300", this is still a way shy of the 1020 it should be going to. Everything in the settings correctly spots that it can go to 1020, it just isn't doing it.
On the plus side, the fans appear to work correctly and cnext.exe no longer commits hari-kiri at every logout. Also, in this brief test, nothing has elected to wander around in the machine's NVRAM with spiky boots on. Unfortunately as I would like all the grunt of my GPU back I will not be evaluating this version further, so the jury's still out on whether that little annoyance is fixed.
Reverting to Catalyst 15.11 again.
I had found FRC didn't work and at first go over 144 and then I had to disable it otherwise it would lock my fps at 55 and not use my GPU constantly, after turning off FRC it was using at normally again but I also reverted to Catalyst as IL-2 Stormovik: BOS running crossfire runs so much better on Catalyst 15.11.1. it's a DX9 title but the develop supports Multi GPU so no need to select the new option in crossfire for DX9 games with no profiles. Freesync didn't work on IL-2 BOS running Crimson either.
Just wanted to check and make certain everyone was following the correct process when updating drivers:
Or you could stop windows from installing hardware drivers always which is better since when you connect the cable Windows could break it as it''s done in the past with AMD hot fixes.
Go to System / Advanced System Settings / Hardware / Device installation settings and select no.
Even after running AMD Cleaner restart again then run CC cleaner and remove all the AMD registry entries. restart and then install.
I've heard some users claim Win 10 ignores that setting, hence my suggestion to disconnect network connections.
It was recommended by Matt from AMD. It works, hence why your device is listed as Microsoft basic adapter not AMD after restarting.
It stops hardware driver updates, they probably got it mixed up with Windows updates.
