OC help

[Matrix]

I'm trying to OC my e6400, if I increase the fsb even by 1mhz when I try and turn the comp on the fans will run for 3-4 seconds and shut off. It does this 3 times before loading the default BIOS settings and returning to stock frequency. I know I have a cheapie board (asrock conroeXfire edition) is that the problem?

this sounds pretty wierd,what kind of ram do you have?
you bios may have some kind of lock or something that doesnt let you overclock.
