DDR2 Latencies

I've heard a lot of talk on the forums about how DDR2 memory timings are not that important on the Intel platform. Here are some tests run at 3-3-3 versus 4-4-4 using Corsair 6400C3 and Yonah. You tell me if there's no difference. Running SuperPi IM is not very revealing because the test is so short. 32M shows latencies do make a difference. Think about track and field. The difference in time between the fastest and slowest runner in the 100 meter dash may be less than a second. On a longer race like the 1500 meters, the difference may be 15-20 seconds.
