Well, overclocking PC2700 to PC3200 speeds is bad news in my opinion... That PC would be terribly unstable.
It would highly depend on whether he has adequate cooling, the quality of the memory, and whether his motherboard even supports it or not. For all I know, overclocking may be locked out completely from the BIOS. Also, overclocking the memory that much would decrease its lifespan by at LEAST 50%. Even though it's only 20 megahertz, that's still a lot for such a tempermental piece of electronics.
