MSI R9 390X Issues

This post isnt about the Dx11 crashes, it's about something different. I have an MSI R9 390X running to a PB287Q ASUS monitor via DP 1.2. When playing any game if I bump up the voltage to +100mV or set the power limit to 50% the screen flickers with what seems to be signal loss. I assumed this was my PSU not pushing enough power or a faulty cable, replaced the cable and the problem happens albeit less frequently when i undervolt/underclock the gpu. So it's not the PSU or DP cable. Now I figured maybe it was a faulty card, so I hooked it up to a 1080p HDMI monitor and I could push the voltages/clocks all over the place without any issues, so it's not the card, it's something specific with the card,DP,or my monitor. Here is an example of what happens. September 17, 2015 - YouTube


For a heads up I am running up to date everything, drivers, bios etc etc. 15.8 Catalyst Beta, although this has been occurring on previous driver versions as well. I have also tried clean installations. I should also mention that pushing the voltage/power limit up only increases the frequency of the signal flicker, it still happens on completely stock everything (driver/settings), just less frequently. amdmatt ray_m I would very much appreciate someone taking a look at this as I am at witts end trying to figure this out.
