The results are quite logical. Faster memory leads to faster overall performance. I cannot say that DDR480 SDRAM guarantees significant performance growth, however, the average advantage of 2-3% is quite noticeable. Almost the same results can be obtained without involving the new features of the E core revision: all you need is simple memory overclocking by raising the clock generator frequency.

So, we have to admit that the enhancements of the K8 memory controller such as support of faster DDR-I memory types than the DDR400 SDRAM can really be efficient only for those users who intend to have their system running in the nominal mode with default settings. Overclockers have been able to have their memory bus running at higher speed for a long time already and with a way more flexible configuring options. The performance in this case remains about the same.
