Every now and then I see people talking about wanting faster memory for overclocking their CPU. Huh? What's the relationship between memory speed and CPU overclocking?

Thanks in advance.

Well, on almost all recent Intel chipsets, Intel implemented a memory speed multiplier setting into the chipset. And with CPU multipliers locked, that leaves only raising the FSB speed as a mean to overclock. With a FSB:RAM ratio, the lowest of which is 1:1, that means that you also raise the memory clock speed. Which generally means that you have to purchase faster memory to overclock. Then again, most good DDR2-800 memory will overclock to 450Mhz without an issue, when you raise the RAM voltage a tad.
