You seem somewhat confused. Can you go into your BIOS and tell what your FSB/DRAM ratio is? "AUTO" would be good. That will give u the most stable settings.
Overclocking your memory without synchronizing you CPU brings very little benefit.
Maybe you were overclocking your CPU? This little utility will tell u what kind of CPU you have:

I'm sure we'd be interested in knowing.
