modify the CAS timings. my understanding is that these settings decrease various wait times in the DDR interface. Because these wait times are in clock cycles, and the DDR clock on the 8315 RDB runs slower than on some other 83xx platforms, we can dial down these values without a problem, thereby decreasing the latency of memory a little.
