But once it becomes unstable, how do you know which voltages to increase, i.e. core, chipset and memory? Do you add like .025 or .05 volts to all, just one, and if so which one? To this newb it seems hard to tell which needs the boost. Any advice is appreciated
I would divide and conquer. Test the max FSB, the max memory speed and the max CPU speed by isolating each variable.
Drop the CPU and mem speeds way down so they don't get in the way and then raise the FSB until the system becomes unstable. Then bump the RAM speeds up by itself until the system becomes unstable.
Ditto with the CPU, until it becomes unstable or temps get "too high".
Try increasing the voltage in each of the steps (NB, RAM, CPU) once you've hit a wall and see how the system reacts to small increases.
Once you have the max numbers written down, you can plan your attack on getting the max CPU speed while 1)staying within the limits of your motherboard and RAM which you now know, and 2)at what point you will need to increase voltages on each part.
Hope that helps, feel free to correct me if I'm wrong, I'm new at a64 overclocking as well.
