I just bought ati 9550 and tried ati tool 0.0.23 and it's cool BUT i want to squeeze my tiny little video card a little bit more. Ati tool works stable (without artifacts) at 380 core. Will flashing to 9600 give me 20 more MHz (to reach 9600 Pro rating- 400MHz) or my core is limited to 380 just because of it's bad manifacturing? My RAM clocks from 400 to 422 MHz. My second question is how much can I overclock 400 MHz video RAM?
