6990/6970 idle question When running a single 6970 the card idles at 0.9 v 250 MHz, 150 MHz. when stressed it bumps up to 1.175 v. at default clocks of 920 MHz 1375 MHz. When I crossfire the 6990 and the 6970 the idle voltages change? idle voltage and freq for the 6990 + 6970 GPU1 0.9 v 250 MHz, 150 MHz GPU2 0.9 v 250 MHz, 150 MHz GPU3 1.150 v 250 MHz, 150 MHz the 6970 is stuck at 1.150 v I have been flashing different BIOS images and sometimes the idle voltages will match and bump up to 1.175 volts when stressed. Now no matter what BIOS image I use that worked before with matching idle and load voltages. Any ideas???
