I ran across a thread at TechPowerUp that was discussing the power saving benefits of decreasing the idle clocks on 4870 cards. I'm a big fan of low idle power utilization, so I got to work attempting to modify my X2's bios with a similar change. I started by decreasing the idle clocks on the slave GPU to 200mhz with RBE (leaving memory alone for now). I flashed the bios onto the card, rebooted the machine, and found that the idle clock was still 507mhz. I flashed back the original bios and it's all working, but I'm a little hesitant to try doing both bioses at the same time without seeing some positive results. I only changed the power saving clocks, leaving the UVD clocks at 507/500. I'm not sure if that would make any difference, but I'd like to have UVD kept at the stock clocks.
Has anyone successfully modded the X2 bioses to have lower than stock idle clocks? If so, what did you do?
