i used ati tool, since the memory sucks so much, i clocked it to 180 ( def was 166 on my card) the memory i have is not ment for overclocking, if i had some bga ram sinks, i might be able to go farther, but i don't. i used 3dmark03 and got 1113( or something close to it) after overclocking. also, you have to download a special driver for a 9200 for ati tool.
