Hi, new and all I am trying out the ATITool today and I wanted to know your opinions about this. I have a 128MB ATI Radeon x600 Mobility in my laptop which I want to overclock and these are the numbers I got: Default is 400/230 and when I let the prog search for the max they peaked at 472/291 and then settled down at 461/289 and it didn't go lower than that after running both the core and memory test for about 1 hour. I am taking the safe route and want to set the card to 451/279, so taking 10Mhz off from the figures AtiTool gave me. What do you think, am I being too cautious and should use the figures ATITool gave me or is better to set it 10Mhz lower, just in case? And also, will the increase be really noticable, seeing it will be 51Mhz higher for the core and 49Mhz higher for the memory? BTW, I obviously take responsibilty for anything that happens to my card, so speak freely Cheers.
