WARNING! Bad batch of XFX GPU's - 6800XT MERC319 CORE.

Its done for me, I'm out. Worst possible situation, when you have noisy product for 1205$ (price in day of bought) and YOU CANT FIX IT. There is no way of removing coil whine on those cards even at 30FPS.
- Undervolting
- Overclocking
- Trying 4 PSU's (Low End, Mid Range, 2x High End)
- Burning in in furmark for 24 hours
- another 24 hours left in games (where coil whine was sounding loud)
- Leaving game ON with noisest whine for 24 hours
- Different position of the PC (Horizontal vs standard)
- checking all possible options in BIOS and system
- UPS/ no UPS (its visible on the video)
- Holding up with my fingers and squeashing the card in few places - nothing
- Different Wall sockets
- tightening whole case, every screw
- loosing screws on back panel and removint it entirely (in case)
- Vsync, ERP Ready, Freesync, Spread Spectrum - tried disabling and enabling - nothing
- Using GPU support and without it
- taking PC in my hands and lifting it - nothing
- Disconecting EVERYTHING, including all fans, RGB, USB - leaving only POWER connected
- There is no way of dealing with it, dont believe anyone who says it's best card. it's one of the WORST.
