Hi, I've got flickering every time I load ATITool (around 10mS flickering). That's mean flickering every time I start up windowsXP and it happend when ATITool (via auto run) is loaded into windows. I think it is because it stock GPU is 500MHz, and ATITool set GPU to 499.50MHz due to its frequency or something. It is still working, just annoying flickering. I am using ATITool 0.25 beta16pre1 as this the most working version to x1600pro. Now I am trying ATI Tray Tool 1.2.6 beta 930 as it offer overclocking for x1600 too. But it doesn't provide GPU temperature link to MBM, so I can't display GPU temperature on Desktop Side Bar . Just see for few days before I go back to ATITool... Regards, Arto.
