How much could i over clock a g force 4 mx 440

i just wanna know how much i can overclock a g force 4 mx 440 whoever has one please could u tell me how far u have over clocked it thanks

I have a Inno3d geforce 4 440mx

i can only hope that you dont have this one.

default is 270-405

i can reach 300/480 and is stable.
but i've read where people that had good mx440s got to like 315-320 and like 500-515 memory.I'm not going to buy another inno3d,my next card will be a ati9700pro,even though i like nvidia alot.
