it's common on crap overclocking board to do a pin mod to jump to the next higher fsb. You can even do it on Dells. It essentially fools the mobo into thinking that a 1066 fsb cpu is in the socket, so the mobo sets the correct fsb/ram and fsb/pci ratios, giving you stable 1066 fsb operation. Not every mobo out there will take to a pin mod, as some use different methods to determine the cpu fsb frequency, but they are the exception and not the rule.
Very long discussion on the topic here:

Note my ridicule of the proposed method about a dozen posts from the top. The mod works as is, but it's not the easiest way to do it. Also, on page 4, I list all possible pin mod combinations. 0=has voltage, or connected (zero resistance), while 1=no voltage, or not connected (infinite resistance). To change a 0 to a 1, put tape over the pad. To change a 1 to a 0, you must pull up voltage either from a standard voltage pin (as shown in the pic above), or from another BSEL pin that has voltage to it already (the simpler, faster, easier way), using conductive ink.
Hope that helps.
