Memory tests
Starting off, as always, with a look at bandwidth and latency.
Bandwidth results between all three protagonists are just about equal, according to ScienceMark 2.0.
Latency, however, is a touch behind that of an nForce4 SLI Intel Edition when run with identical memory timings. EPoX's 5LWA+ even has a 20MHz+ FSB-created speed advantage over NVIDIA's board.
Pifast, however, runs at the same speed on both. Chipsets on one platform may show a very slight performance deviation from one another, but a different platform can be markedly quicker/slower.
