Memory Performance:

It looks Asus did something right as the Everest read test for 1,333MHz+ is far greater than the normal P5K3 Deluxe, as both memory are set to the same timings. The write speed seems to benefit from the extra performance, but it's no better than the standard DDR3 memory in this case. One of the improvements touted was the lower latency and this is applicable to an extent, at 1,333MHz and over it drops by a fair whack although we don't feel it's quite that revolutionary.
