Good Nvidia Overclocking tool?

Question

I have an Nvidia FX5500 at 250mhz core clock and 133mhz memory, i recently bought this card from my friend and he had it overclocked to somewhere in the 300s. I was wondering what a good overclocking tool would be (besides ntune, it wont install) and what are some good overclockign frequencies for this card.

P.S. running Windows XP SP2

Also try ATI Tools. Some Nvidia cards respond to it.
