How to overclock?

Use riva tuner to oc those cards.

Riva tuner is a free download from www.guru3d.com/rivatuner/ they hav a guide on to oc too!!

Remember overclocking can harm your graphic card.

that card is of no use with todays games. So its better if hes able to get every bit of perfomance from it. Like someone somewhere somehow told "overclock untill it dies nd get a new one". Older cards are much stable nd wont probably burnout if oced, just brings BSOD.
