Just bought myself a new rig and am about to start attempting to overclock it. I was just wondering what sort of speeds I should be aiming for? What temperatures are dangerous for the CPU, how high can I go? I'm working with an AMD Athlon 64 3700+ San Diego cooled by a Zalman CNPS7000B. My motherboard is an Asus A8N-VM CSM Micro ATX if that makes any difference.
