In the first example, Everest reports a 400 MHz FSB and 533 MHz RAM. In the second, it reports a 266 MHz FSB and 533 MHz RAM.
I understand the double and quad data rates. The confusion was solely based on the reference clock.
My Everest comment was based on the quote above. In both cases you state 533 ram. I see now that I didn't read your 1066 bus reference properly.
