Hey guys! dostov here from TRP Forums. I'm currently trying out RBE v1.19 and the new voltage registers options on a 512MB reference HD4870. I'm trying to build upon the Asus Top BIOS to both increase the 3D voltage and decrease the 2D voltage. Correct me if I'm wrong, but the Asus Top BIOS has locked voltages. So, what I first did was to enable superior powerplay with RBE to get rid of the locked voltages. Then, I upped the 3D voltage to 1.3250v in register 18. Others values were okay by me, and already a big improvement over locked voltages, so I left it as is. So far, after a dozen or so different attempts, I still can't get the voltage to go down when in 2D mode. It always is at 1.3250v according to GPU-Z, which I found to be very precise to read voltages in my own experience. Here's a screenshot of my current settings in RBE: Do you guys see anything I would've done wrong that would explain this issue I'm having? Is it even possible to do what I'm trying to do? Thanks in advance for the help, it's much appreciated.
