There's a difference from the advertised speeds and the related speeds.
DDR RAM stands for Double Data Rate. So if you have 400 MHz RAM, it's really only 200 MHz, but because it's dual-pumped, it's doubled.
The Core 2 Duos (and some other CPUs) are quad-pumped. So their speeds are X4. So if the FSB is 1066 MHz, it's technically only about 266 MHz.
It's hard to explain. Read these wiki articles:
