Hello, so i'm getting those blackscreen errors with this card (Sapphire HD7870 OC 2GB) with afterburner I lowered the voltage but checking with hwmonitor and other programs showed me it was fake and voltages stayed the same, but Trixx and Afterburner would let me do it. Trying to solve blackscreen issues I flashed another bioses from ASUS models, it worked fine, but the blackscreens stayed. Now I flashed back to my model with the bios hosted in this site, but I can't change the voltage in Afterburner anymore, it's empty now, I guess the bios isn't the same or something... So could anyone with my card model open GPU-Z and post it for me please? Also tell me if you experience blackscreens randomly, thanks!!!
