I'm using the AMD blockchain drivers with Afterburner on Windows 10 Pro v1703 and it works fine. If you updated to the Windows 10 Fall Creators Update (v1709), that may be your problem as the blockchain drivers don't support the FCU.
I'm using the Aug 23 Blockchain driver on several rigs running v1709. FCU will replace the driver but you can remove 17.7.2 (or whatever FCU installs) and reinstall Aug 23 Blockchain driver.
But, if I wan't to try Claymore 10.1, do I have to disable antivirus completly? Windows defender says \cuda7.5\EthDcrMiner64.exe
is a Trojan called Tiggre!plock
I also want to try 17.10.2 or above. In order to enable "compute" I will have to install AMD settings and thus Wattman will be installed. But does not Wattman interfere with other oc and monitoring software like Afterburner and OverdriveNTool? I installed 17.10.2 and OverdriveNTool is unable to set the clocks and voltages. Wattman works but it's not the ideal tool.
Since the blockchain drivers don't support the Creators fall update, there is no point in updating to v1709. The blockchain drivers install and worked for me on v1709, but it makes the Windows UI very unstable e.g. you can't select the Taskbar icons or Windows menu. If you want to stick with the blockchain drivers, it's best to stay on v1703 and defer the Windows feature updates in the Group policy editor until a stable version of the new Crimson Relive compute toggle drivers is out.
gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update ==> Defer Windows Updates ==> Select when Feature Updates are received
There you can defer Windows version updates for up to one year.
While in the Group Policy Editor, you can also keep Windows Update from updating the the drivers.
gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.
Completely disabling Windows Update is unnecessary and opens your network to zero days.
The release notes for the Crimson Relive 17.11.1 driver that is out also mention the new drivers have a known issue with 12 GPU's in compute mode.
