The ASUS RX Vega 64 is my fourth RX Vega card with in a half year. The first 3 came from Powercolor. If it possible that all RX Vega cards with Hardware revision C1 has stability issues?
The first had an damaged fan bearing.
The second wouldn't post up. The motherboard shows Q-Code 62.
The third had graphics errors.
Every time I try to play Titan Quest V1.57 with my ASUS RX Vega 64 I got a black screen. The Windows reliability monitoring shows me a
Live Kernel Event 117. I used Win Debug to read out the dump file.
It shows that atikmpag.sys crashes.
The Radeon software version used has no effect on the stability. Titan Quest crashes is present from Radeon Software 17.10.1-Oct6 to Radeon Software 18.8.2.
Additional I have problems with the Radeon Performance Overlay (STRG+Shift+O). If the Radeon Performance Overlay is open and I press ALT+TAB I got a corrupt desktop Colors if I ran Windows 7 in Basic or Classic design. The application that cause that problem is Diablo III x64 client. The RX Vega 64 draws around 60 Watt. If Aero is enabled alt+tab works normal with the RX Vega 64.
I don't thing that is a problem with the power supply. If Titan Quest is running the RX Vega Card draws a round 30 watt and the fan is turned of.
Steps I have tried to correct that issues.
Uninstall all Radeon software and Chipset drivers with AMD Cleaner utility and DDU in Windows Save mode. Install the last Radeon software and AMD Chipset drivers.
Reset the Radeon Software to defaults.
Lowering the power limit in WattMann to -50%.
I also tested the GPU in my older System with a Clean Windows 7 x64 installation. The same errors happens.

8GB Kingson DDR3 RAM
AMD Phenom II X4 965
If I install my old HIS Radeon HD 7770 1GB I have no stability issues. Titan Quest and the Radeon Performance Overlay are running fine with Aero or Basic design.

After I had more issues with my Vega Card I RMAd it and got back money. One aditional issue was graphic glitches in Diablo III. After this I checked out that Vega only reports 8176MB of V-RAM. This card shoud have 8192 MB of V-.RAM.
Now I have installed an RX480 Nitro+ OC from Sapphire Tech. It works stable in OC Bios. If I ran Titan Quest I got a "GPU Core Power Peak from 256,92W!
Can it be that AMD Powertune fails if Titan Quest is running and Graphic Cards can consupt much more power when specified? In most other apps I got a GPU Core Power Peak around 180W.
