Is there a straight-froward way to determine a CPU or chipset/board base frequencies?

DDR2 memory seems to always use a base frequency which is half of its effective frequency- is DDR3 like this as well?

How about the CPU and the FSB frequencies? I rarely see base frequencies mentioned in specifications on vendor sites.

CPU Speed is Base Clock x Multiplier

FSB is Base Clock x 4 = Effective Rate

DDR2/DDR3 is Base Clock x Memory:FSB Ratio x 2

Default base clock for Intel Core 2 Duo/Quads is 266MHz.
