Hi , i just bought me a Sapphire X1900GT and got a 2nd rev card. Afaik the PCB is different to the old one and they changed the arrangement of the mosfets. Till now i found no prog that lets me Change Vgpu oder Vmem. I tried ATI-tool 0.25 beta 16 and latest version of ATT latest version. Both can change clocks , show temps etc but there is no option for changing voltage. I even tried modding bios with Rabit to 1,35Vgpu and flashed it but as long as i can´t clock a bit further and Temps are the same i am convinced it didn´t work. Any ideas?
