Introduction

The main reason why DDR2 memory was so disappointing during the beginning launch was because of the extremely loose latencies.  Even with the benefit of carrying twice the amount of data back and forth, DDR2 simply could not keep up with DDR in terms of performance.  It was quite hard to justify the need to move on to DDR2 when the performance was so lacking.  Fortunately for enthusiasts, Corsair was the first to discover the great potential in Micron fatbody D9s.  These chips are amazing.  It ran extreme low latencies and responded very well to increased voltages.  The lower latencies gave an incredible boost in performance, easily surpassing the performance of regular DDR.  Not only did Corsair had the first DDR2 memory to run extreme low latencies, they were also the first to break the 1GHz barrier.  Talk about killing two birds with one stone!

A little after the release of the 5400UL, Corsair announced the release of the 8000UL.  The Corsair PC2-8000UL was the best DDR2 I have laid hands on.  It was amazing.  It overclocked extremely well with extreme low latencies and easily broke past the 1GHz barrier with slightly looser timings, with timings tighter than rated.  The goal of the 8000UL was to run 1GHz with timings of 5-4-4-9.  If it was able to run extreme low latencies, then why is Corsair still pushing their PC2-5400UL?  The reason is that the 5400UL aims for the lowest latencies possible.  My first thought was that it was made to be the best DDR2 memory in the tight timings crowd.  Is it true?
