basic directions?

I have read and know very well by know that it is pretty pointless to overclock this nVIDIA GeForce FX5200 but I am going to do it anyways. With that being said how should i go about it? Last night i started it up and ran Find Max Core for a few hours and it went from 240 being default to 308. After those few hours i ran Find Max Mem and ran that over night and woke up to find out that it overclocked to much and rebooted the computer. So today, i tried to lower the core clock and then find max on the mem again and in about 1 minute computer crashed all over again. How should i do this? should i run find max core for about 15 minutes....then abort and do find max mem for 15, repeating untill it finds the max? should i set the clock safety range to 308 since that was the last working speed before the crash?
