I was using the 400MHz strap. With the 333MHz strap I don't have that problem at least not noticeable in EVEREST. But the problem is still there because it doesn't matter what you select for Ai Clock Twister it still fails at high FSB.

We could say that it's because of the X48 chipset but that doesn't explain why all other ASUS boards with newer chipsets also fail at high FSB with Quads.
