Hello.I Have the same Problem when i am playing DOW 3, after random time on the screen are pixels with diffrent colors and the monitor lose the signal(but music shuts down to and i have to restart). When i play Crysis 3, AC Syndicate or prey on maximum i dont have any problems.
And when i look in "dxdiag" at "grafic-display" it shows me only 4096 Gb VRAM
asus crosshair V formula
Exactly the same Picture and i have a LG 34UC88 with WQHD (21:9) ,too
My Card is from XFX
mh now, question a defect oft the card or a error on driver or whatever.
I have a Philips 34 WQHD 3440x1440 21:9 same and xfx.
new Moment: When i play on 2048x1080 then i have no Problems only on 3440x1440p on 21:9
Okay only on BF1 when i Play pubg then Crash by 2048x1080
When i switch to the "Power save" mode in AMD Crimson, i can play without problems. And the temperatures goes only up to 75 °C in balance mode up to 85°C .
But that dont can be the solution, its only a solution for the mean time. When i buying such a expensive graficcard then i want that it can run on max. for few hours.
Please can you provide a DXDIAG report and attach (do not copy paste) the report to your next response?
If you can also provide some steps on how best to reproduce this issue that would be helpful along with the essential INFORMATION REQUIRED WHEN POSTING A QUESTION
Here is my Dxdiag Report:
DxDiag.txt - Google Drive (Windows 7 64-bit)
The Crash (look at picture above) comes after random time by playing the game DOW 3 with this settings and balance mode(AMD Crimson):
Texture and grafics are on Max, physics: Medium
I play with the Resolution 3440 x 1440
When the game crashes, comes this colorful screen and after few seconds the monitor lose the signal. Mouse and Keybord lose their funktion and i have to restart the computer. Sound stop,too. So I think the whole Computer crashes. Temperature from GPU is 85 °C and HBM 86°C.
The graficmemory goes only up to 4097Mb and never over this 4097Mb (in dxdiag is writen that i have only 4096 MB VRam but the graficcard should have 8GB?!)
When I play in "Power save" mode (AMD Crimson) it dont crashes full only the game sometimes?! And the GPU temperatures goes only up to 75°C (HBM 80°C).
Other Games have no problems on Ultra settings and same temperatures.
