I865G Mobo Question!

[OneOfTheseDays]

If i have a 533 fsb CPU, can i run my memory at DDR 400 and above? I have a single stick of PC 3500 memory that can do 440 mhz, will I be able to run it at those speeds if I have a 533 FSB CPU. THe mobo i have is an AOPEN AX4SGN i865G motherboard. I'm trying to run my 2.4 B 533 CPU at 170 FSB with X2.50 on the memory. It won't boot up. What's the problem? I've tried everything I could think of.
