Hi. I know my videocard is very old and i will be getting a new one within 1-2 months, but i'd like to overclock my current card, a Geforce 2 MX400 64mb, until then. At the moment, my core clock is 200mhz and my memory clock is 143 mhz. What could i set them to without having to get a fan or something? Thank you in advance.
