RBE v1.19 just got launched. If you have any ATI card that is equipped with a VT11xx, read this and put your register values into your BIOS using RBE to make them permanent. v1.19 - Fixed a startup bug causing the main window not to show up. - Added experimental voltage register access. RBE automatically figures out if the card's equipped with a VT11xx. Just use register 15 for underclocking/undervolting and register 18 for overclocking. Register tweaking will override the voltage table. Still, you should adjust your powerplay settings according to the new register values.
