Memory tests
Two sets of results you need to watch out for here. Firstly, how well does the Dell XPS Gen-4 compare with a near-identical HEXUS test system that uses a Pentium 4 660 instead of the Dell's 560?. Secondly, how well does it compare to two Athlon 64 systems with 3500+ and 4000+ CPUs for the SCAN and MV models, respectively?
Memory bandwidth and latency are both reasonably similar to the HEXUS test system's. Of course S939 simply runs away with it where latency is concerned.
Still pretty close to the HEXUS rig.
