The chip wasn't working as it should at 2Ghz...It doesn't scale better than linearly,that is impossible.It just works as it was designed at 2.4Ghz since the IMC freq. and L3 latency are at the place where they make the rest of the core most efficient.

PS You never saw A64 at say 2.8Ghz perform worse with higher latency(cas 5) and lower frequency memory ,than same CPU with low latency and high freq. memory?This is not exactly the same comparison since K10 is much much improved design,but it gives you an idea,that although the IPC stayed the same,chip efficiency was lower than in the second case scenario(say that IPC of second case was a baseline)
