Hi Russ, I don't know what the current state is (I'm running a slightly older version than you), but we ran into a problem with the 83xx SPD code being able to recognize faster DDR2 memories. There was a whole series of nested if/else if statements figuring out if it was DDR400, DDR333, etc., and then figuring out effective data rates and CAS latencies from that. What we ran into was that (at the time) it would only figure out upto DDR400 and we're using 533. Since we're only using the one speed of RAM for this release of the product we just hardcoded values into registers and decided to look at fixing SPD later. Don't know if anyone else has yet. Know it doesn't help you much, but it gives you some place to look :(.
