Solved Memory Over Voltage?

OK so what is memory over voltage and how does it effect the system? Should it be high or low? And, what is memory frequency? Should IT be high or low?

I didnt understand exactly what you want to know, but memory overvoltage means to set memory to work at a tension higher than nominal. It's useful to overclock memory (increase frequency). Normally 10% of overvoltage in a DDR2 module may allow an overclock up to 20%, but you may also need to increase memory timings.
