The only tool that works is RivaTuner 2.06 which in fact is not programmed to support rv670(HD 3870) but does work fine overclocking....

Yep, same here tried the other two also. Tray Tools just locked my system when trying to set the clocks. Either way not too bad with the bios change and a ThermalRight V2. Benched 891/1400. Should be interesting when there's full support and some voltage control. Thanks for replying.
