Got this card with my new athlon 1.33ghz. I emptied my pockets buying this system, so I would really prefer to avoid frying anything, but I do want to overclock the geforce a bit (its a bit slow for a geforce2)..I believe the base settings are 200 mhz core and 166mhz memory. I OC'ed the core 20 mhz, and the memory 33mhz...works fine with that and got quite an improvement in the score. with the OC'ing my chip runs at about 61 degrees celcius..how much more would you say is safe, without adding any extra cooling?
