Overclocking Asus Guppy mb with a celeron D 2.9ghz processor?

I have a presario sr1503wm and according to my hardware detection program my motherboard is an asus guppy. The only other information given is the chipset which is a intel845GE (brookdale GE) + ICH4. Can this motherboard be overclocked? If so how? I havent been able to dig up any information on it. Its a pretty decent base pc but I'd like more out of it.
