YEAH i had a test about that before.
Mine CAS Latency was set to 2 at beginning, and it worked pretty stable(reboot roughly once 3 days), yet one day my WIN2k began to prompt DUMPING MEMORY, so it returned to 2.5 and I tried setting it back and it never worked any more...WELL according to sandra there's only 17 points difference (6674 v.s. 6657)....so I guess for ur system stability, just leave it.
