yeah, your kind of asking to get blood from a turnup. thats a budget gpu. was never intended to overclock. you may be able to up the core clock maybe 30 to 40 mhz. make sure the fan is at max rpm, if it's even adjustable.
i had a 9500GT 1gb (biostar) and i could overclock it a lot from the factory settings with no problem =)
try not to push it too hard, make it graduatly and you'll probably archieve a nice overclock
also, try too keep it as cool as posible =D
