Hi jim kelley; Re the i820 SDRAM recall, noise and clocking problems. I know that you're not going to understand this, but that's okay, it's from Intel's design manual for the i820, and it is talking about the RDRAM interface:

Page 36 (labeled 2.8)
Additionally, coupled noise can greatly affect the performance of high-speed interfaces. Just as in source synchronous designs, the odd and even mode propagation veloicy change creates skew between the clock and data or command lines which reduces the maximum operating frequency of the bus. Efforts must be made to significantly reduce crosstalk, as well as other sources of skew.

In fact, the above is an interesting document, and I will likely post a lot concerning it.
