How exactly do I know when I need to loosen timings and how much I need to loosen them? My situation is this. I have an AMD Athlon 64 3000+ and have overclocked the FSB from 200 to 250. I made the number for the RAM 166 so it works on a 5:6 ratio. I want to overclock it farther, because I know I can get at LEAST another 30 out of the FSB. My question is simply: how do I know when I need to loosen or change RAM timings OR voltage supplied to it?
