If you read the reviews (KT7A), you will see that they are all done on 100 FSB TBirds and run at up to 148 Mhz depending on the memory used, some on unlocked 1 GHz, and some on 1.2 GHz.
Many people are finding that the 1.2 GHz are shipping "Unlocked".
The 266 FSB will be available shortly, WTF get one and tell us.
