You are not wrong, just misinformed.
There are many tricks which can be used to get the 1066mhz module memory up to 1200, 1333 or 1600mhz.
First lets take the Crucial module number CT3KIT12864BA1067 which can be found right here
# Module Size: 3GB kit (1GBx3)
# Package: 240-pin DIMM
# Feature: DDR3 PC3-8500
# Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.5V • 128Meg x 64 •
Now lets think about things.
There are 2 ways to get the speed of 1600mhz.
First: increase the latency to 9.
Second: increase the memory voltage to 1.64 and latency to 8.
At the end you will not be spending much for such speed and could save some money to get good cheap 6X2GB DDR3 modules when the price goes down by next year altogether with Windows 7 if that is the case.
