IC7 max3 oc'ing problem, pls help

[rollier0401]

ok, i just upgraded my stuff today, i picked a 2.4c, the max3 mobo, and an additional 512 of xms twinx 3200.

the problem i'm having is this, if i go with any other than a 220fsb after post my screen just stays blank, (from what i can tell it posts succesfully) any ideas as to what would cause this?

addt'l info: ram timings are spd, divider has been tried at 3:2,5:4, and 1:1, agp freq is fixed, tried the mem voltage at 2.6,2.7,and 2.8

my vcard is a visiontek 9800 pro, and i'm using a dd maze w/c setup
