Overclocking is a very black art. Try running the tests with the
exact same settings as your friend.
One possible pitfall is memory access pattern, it is possible to only get down to half the effective memory speed when comparing two CPU speeds that are almost the same This happens when the slightly faster speed requires stepping down to a much crappier memory access pattern.
Also some memory controllers drop to a lower speed as you add more than a certain number of memory modules (bus loading problems). We had 2 supposedly identical servers shipped, 1 full of 1GB memory sticks the other with nice 2GB memory sticks .....
