v4, TDP Max, Power Limit and TDC Limit all set to 50% in the Bios. VDDCI back to 1000mv, VRM Frequency back to stock. GPU Clock 2 back to stock, tuned the fan profile

First at all: Thank you for your help and suggestions, guys!

The resolution is 1920x1080 and the refresh rate 60 Hz.

But I don't think it's just a matter of the monitor loosing signal, because the black screens are from that kind which are freezing the whole system, I even can't ping it from another PC, only way to shut it down is by holding the Power Button down for several seconds...

Unfortunately, I don't have a spare PSU/PC to test the GPU with.

I will try generaleramons newest mod and report back. Stay tuned :-)
