    I've a p4b533-e and 2x256 corsair ddr400 at 3/4 ratio and it work perfectly.

    In test i put my fsb at 150 mhz with mem at 400 mhz (PC3200) and no problem.

    I also have a P4B533-E but with one stick of 256MB Corsair XMS 3200 CAS2 ram

    By setting:

    RAM at 1:1 in bios, and dipswitch #6 to ON, the real RAM ratio becomes 3:4
    (can be confirmed using the wcpuid program and SiSoft Sandra benchmarks).
    With this setup, and the FSB at 150 (lock AGP/PCI at 66/33 in the bios),
    the Corsair RAM is actually running full ddr400 speed.
