Problem with Asus DCUII OC R9 290

[gregorisvas]

Hello everyone!
I have a problem with the aforementioned GPU for the last 2 weeks (since I bought it anyway..). Sometimes, without any particular reason, the screen will flicker with blue dots/lines. Once I turn off the monitor and then back on again, these dots/flickers disappear and may come up after a reboot. I had an Enermax Liberty 620W (36A on +12V rail) and thought that maybe the PSU was to blame, but even after I installed an EVGA Supernova G2 850W the issue persists. This is what I mean https://drive.google.com/file/d/0B8v...ew?usp=sharing . Any ideas;

Have you tried:
1) change the BIOS switch
2) Update your drivers (try beta if you are up to date)
3) When running Display Port, check that your monitor input is set Display Port 1.2 ( done in monitor on screen setup, not the CCC or computer setup)
4) over/under clocking the GPU
5) changing monitor input (if on DVI, try HDMI or Display Port), Display Port is much preferred
What monitor are you using?
